Detailed Description

Low-level parser for C++ arrays.

\n-
Deprecated:

\n+
Deprecated:
Use pqxx::array instead.
\n

Clunky old API for parsing SQL arrays.

\n
Warning
This parser will only work reliably if your client encoding is UTF-8, ASCII, or a \"safe ASCII superset\" (such as the EUC encodings) where a byte value in the ASCII range can only occur as an actual ASCII character, never as one byte in a multi-byte character.
\n
\n The parser only supports array element types which use a comma (‘’,') as the separator between array elements. All built-in SQL types use comma, except forbox` which uses semicolon. However some custom types may not work.
\n

The input is a C-style string containing the textual representation of an array, as returned by the database. The parser reads this representation on the fly. The string must remain in memory until parsing is done.

\n

Parse the array by making calls to get_next until it returns a juncture of done. The juncture tells you what the parser found in that step: did the array \"nest\" to a deeper level, or \"un-nest\" back up?

Dereferencing operators

An iterator \"points to\" its own row, which is also itself. This makes it easy to address a pqxx::result as a two-dimensional container, without going through the intermediate step of dereferencing the iterator. It makes the interface similar to C pointer/array semantics.

\n

IIRC Alex Stepanov, the inventor of the STL, once remarked that having this as standard behaviour for pointers would be useful in some algorithms. So even if this makes me look foolish, I would seem to be in distinguished company.

The standard streambuf classes provide uniform access to data storage such as files or string buffers, so they can be accessed using standard input or output streams. This streambuf implementation provided similar access to large objects, so they could be read and written using the same stream classes.

This functionality was considered too fragile and complex, so it has been replaced with a single, much simpler class.

Detailed Description

\n

Result set containing data returned by a query or command.

\n

This behaves as a container (as defined by the C++ standard library) and provides random access const iterators to iterate over its rows. You can also access a row by indexing a result R by the row's zero-based number:

\n-
for (result::size_type i=0; i < std::size(R); ++i) Process(R[i]);
\n+
for (result::size_type i=0; i < std::size(R); ++i) Process(R[i]);
\n+
pqxx::const_reverse_result_iterator
Reverse iterator for result. Use as result::const_reverse_iterator.
Definition result_iterator.hxx:196
\n

Result sets in libpqxx are lightweight, reference-counted wrapper objects which are relatively small and cheap to copy. Think of a result object as a \"smart pointer\" to an underlying result set.

\n
Warning
The result set that a result object points to is not thread-safe. If you copy a result object, it still refers to the same underlying result set. So never copy, destroy, query, or otherwise access a result while another thread may be copying, destroying, querying, or otherwise accessing the same result set–even if it is doing so through a different result object!

Run func on each row, passing the row's fields as parameters.

\n

Goes through the rows from first to last. You provide a callable func.

\n

For each row in the result, for_each will call func. It converts the row's fields to the types of func's parameters, and pass them to func.

\n

(Therefore func must have a single signature. It can't be a generic lambda, or an object of a class with multiple overloaded function call operators. Otherwise, for_each will have no way to detect a parameter list without ambiguity.)

\n

If any of your parameter types is std::string_view, it refers to the underlying storage of this result.

\n

If any of your parameter types is a reference type, its argument will refer to a temporary value which only lives for the duration of that single invocation to func. If the reference is an lvalue reference, it must be const.

\n-

For example, this queries employee names and salaries from the database and prints how much each would like to earn instead:

tx.exec("SELECT name, salary FROM employee").for_each(
\n-
[](std::string_view name, float salary){
\n-
std::cout << name << " would like " << salary * 2 << ".\\n";

})
\n

If func throws an exception, processing stops at that point and propagates the exception.

Detailed Description

\n

Reference to one row in a result.

\n

A row represents one row (also called a row) in a query result set. It also acts as a container mapping column numbers or names to field values (see below):

\n-
cout << row["date"].c_str() << ": " << row["name"].c_str() << endl;
\n+
cout << row["date"].c_str() << ": " << row["name"].c_str() << endl;
\n+
pqxx::const_reverse_row_iterator
Reverse iterator for a row. Use as row::const_reverse_iterator.
Definition row.hxx:411
\n
pqxx::row
Reference to one row in a result.
Definition row.hxx:47
\n

The row itself acts like a (non-modifyable) container, complete with its own const_iterator and const_reverse_iterator.

Deprecated:
I haven't heard of anyone caring about row slicing at all in at least the last 15 years. Yet it adds complexity, so unless anyone files a bug explaining why they really need this feature, I'm going to remove it. Even if they do, the feature may need an update.

\n

The slice runs from the range's starting column to the range's end column, exclusive. It looks just like a normal result row, except slices can be empty.

 Factory: Stream data from a given table.

Detailed Description

\n

Stream data from the database.

\n-
Deprecated:
Use transaction_base::stream.
\n+
Deprecated:
Use transaction_base::stream.
\n

For larger data sets, retrieving data this way is likely to be faster than executing a query and then iterating and converting the rows fields. You will also be able to start processing before all of the data has come in.

\n

There are also downsides. Not all kinds of query will work in a stream. But straightforward SELECT and UPDATE ... RETURNING queries should work. This function makes use of pqxx::stream_from, which in turn uses PostgreSQL's COPY command, so see the documentation for those to get the full details.

\n

There are other downsides. If there stream encounters an error, it may leave the entire connection in an unusable state, so you'll have to give the whole thing up. Finally, opening a stream puts the connection in a special state, so you won't be able to do many other things with the connection or the transaction while the stream is open.

\n

There are two ways of starting a stream: you stream either all rows in a table (using one of the factories, table() or raw_table()), or the results of a query (using the query() factory).

\n

Usually you'll want the stream convenience wrapper in transaction_base, * so you don't need to deal with this class directly.

\n
Warning
While a stream is active, you cannot execute queries, open a pipeline, etc. on the same transaction. A transaction can have at most one object of a type derived from pqxx::transaction_focus active on it at a time.

Supporting additional data types
\n \n
\n

Communication with the database mostly happens in a text format. When you include an integer value in a query, either you use to_string to convert it to that text format, or under the bonnet, libpqxx does it for you. When you get a query result field \"as a float,\" libpqxx converts from the text format to a floating-point type. These conversions are everywhere in libpqxx.

\n

The conversion system supports many built-in types, but it is also extensible. You can \"teach\" libpqxx (in the scope of your own application) to convert additional types of values to and from PostgreSQL's string format.

\n

This is massively useful, but it's not for the faint of heart. You'll need to specialise some templates. And, the API for doing this can change with any major libpqxx release.

\n

If that happens, your code may fail to compile with the newer libpqxx version, and you'll have to go through the NEWS file to find the API changes. Usually it'll be a small change, like an additional function you need to implement, or a constant you need to define.

\n-

\n+

\n Converting types

\n

In your application, a conversion is driven entirely by a C++ type you specify. The value's SQL type on the database side has nothing to do with it. Nor is there anything in the string that would identify its type. Your code says \"convert to this type\" and libpqxx does it.

\n

So, if you've SELECTed a 64-bit integer from the database, and you try to convert it to a C++ short, one of two things will happen: either the number is small enough to fit in your short and it just works, or else it throws a conversion exception. Similarly, if you try to read a 32-bit SQL int as a C++ 32-bit unsigned int, that'll work fine, unless the value happens to be negative. In such cases the conversion will throw a conversion_error.

\n

Or, your database table might have a text column, but a given field may contain a string that looks just like a number. You can convert that value to an integer type just fine. Or to a floating-point type. All that matters to the conversion is the actual value, and the type your code specifies.

\n

In some cases the templates for these conversions can tell the type from the arguments you pass them:

\n
auto x = to_string(99);
\n

In other cases you may need to instantiate template explicitly:

\n
auto y = from_string<int>("99");
\n-

\n+

\n Supporting a new type

\n

Let's say you have some other SQL type which you want to be able to store in, or retrieve from, the database. What would it take to support that?

\n

Sometimes you do not need complete support. You might need a conversion to a string but not from a string, for example. You write out the conversion at compile time, so don't be too afraid to be incomplete. If you leave out one of these steps, it's not going to crash at run time or mess up your data. The worst that can happen is that your code won't build.

\n

So what do you need for a complete conversion?

\n

First off, of course, you need a C++ type. It may be your own, but it doesn't have to be. It could be a type from a third-party library, or even one from the standard library that libpqxx does not yet support.

\n

First thing to do is specialise the pqxx::type_name variable to give the type a human-readable name. That allows libpqxx error messages and such to talk about the type. If you don't define a name, libpqxx will try to figure one out with some help from the compiler, but it may not always be easy to read.

\n

Then, does your type have a built-in null value? For example, a char * can be null on the C++ side. Or some types are always null, such as nullptr. You specialise the pqxx::nullness template to specify the details.

\n

Finally, you specialise the pqxx::string_traits template. This is where you define the actual conversions.

\n

Let's go through these steps one by one.

\n-

\n+

\n Your type

\n

You'll need a type for which the conversions are not yet defined, because the C++ type is what determines the right conversion. One type, one set of conversions.

\n

The type doesn't have to be one that you create. The conversion logic was designed such that you can build it around any type. So you can just as easily build a conversion for a type that's defined somewhere else. There's no need to include any special methods or other members inside the type itself. That's also why libpqxx can convert built-in types like int.

\n

By the way, if the type is an enum, you don't need to do any of this. Just invoke the preprocessor macro PQXX_DECLARE_ENUM_CONVERSION, from the global namespace near the top of your translation unit, and pass the type as an argument.

\n

The library also provides specialisations for std::optional<T>, std::shared_ptr<T>, and std::unique_ptr<T>. If you have conversions for T, you'll also automatically have conversions for those.

\n-

\n+

\n Specialise <tt>type_name</tt>

\n

When errors happen during conversion, libpqxx will compose error messages for the user. Sometimes these will include the name of the type that's being converted.

\n

To tell libpqxx the name of each type, there's a template variable called pqxx::type_name. For any given type T, it should have a specialisation that provides that T's human-readable name:

\n
// T is your type.
\n
namespace pqxx
\n
{
\n
template<> std::string const type_name<T>{"My T type's name"};
\n
}
\n
pqxx
The home of all libpqxx classes, functions, templates, etc.
Definition array.cxx:27
\n

(Yes, this means that you need to define something inside the pqxx namespace. Future versions of libpqxx may move this into a separate namespace.)

\n

Define this early on in your translation unit, before any code that might cause libpqxx to need the name. That way, the libpqxx code which needs to know the type's name can see your definition.

\n-

\n+

\n Specialise <tt>nullness</tt>

\n

A struct template pqxx::nullness defines whether your type has a natural \"null value\" built in. If so, it also provides member functions for producing and recognising null values.

\n

The simplest scenario is also the most common: most types don't have a null value built in. There is no \"null `int`\" in C++. In that kind of case, just derive your nullness traits from pqxx::no_null as a shorthand:

\n
// T is your type.
\n
namespace pqxx
\n
{
\n
template<> struct nullness<T> : pqxx::no_null<T> {};

\n

You may be wondering why there's a function to produce a null value, but also a function to check whether a value is null. Why not just compare the value to the result of null()? Because two null values may not be equal (like in SQL, where NULL <> NULL). Or T may have multiple different null values. Or T may override the comparison operator to behave in some unusual way.

\n

As a third case, your type may be one that always represents a null value. This is the case for std::nullptr_t and std::nullopt_t. In that case, you set nullness<TYPE>::always_null to true (as well as has_null of course), and you won't need to define any actual conversions.

\n-

\n+

\n Specialise <tt>string_traits</tt>

\n

This part is the most work. You can skip it for types that are always null, but those will be rare.

\n

The APIs for doing this are designed so that you don't need to allocate memory on the free store, also known as \"the heap\": new/delete. Memory allocation can be hidden inside std::string, std::vector, etc. The conversion API allows you to use std::string for convenience, or memory buffers for speed.

\n

Start by specialising the pqxx::string_traits template. You don't absolutely have to implement all parts of this API. Generally, if it compilers, you're OK for the time being. Just bear in mind that future libpqxx versions may change the API \u2014 or how it uses the API internally.

You'll also need to write those member functions, or as many of them as needed to get your code to build.

\n-

\n+

\n <tt>from_string</tt>

\n

We start off simple: from_string parses a string as a value of T, and returns that value.

\n

The string may or may not be zero-terminated; it's just the string_view from beginning to end (with end being exclusive). In your tests, be sure to cover cases where the string does not end in a zero byte!

\n

It's perfectly possible that the string doesn't actually represent a T value. Mistakes happen. There can be corner cases. When you run into this, throw a pqxx::conversion_error.

\n

(Of course it's also possible that you run into some other error, so it's fine to throw different exceptions as well. But when it's definitely \"this is not\n the right format for a `T`,\" throw conversion_error.)

\n-

\n+

\n <tt>to_buf</tt>

\n

In this function, you convert a value of T into a string that the postgres server will understand.

\n

The caller will provide you with a buffer where you can write the string, if you need it: from begin to end exclusive. It's a half-open interval, so don't access *end.

\n

If the buffer is insufficient for you to do the conversion, throw a pqxx::conversion_overrun. It doesn't have to be exact: you can be a little pessimistic and demand a bit more space than you need. Just be sure to throw the exception if there's any risk of overrunning the buffer.

\n

You don't have to use the buffer for this function though. For example, pqxx::string_traits<bool>::to_buf returns a compile-time constant string and completely ignores the buffer.

\n

Even if you do use the buffer, your string does not have to start at the beginning of the buffer. For example, the integer conversions may work from right to left, if that's easier: they can start by writing the least significant digit to the end of the buffer, divide the remainder by 10, and repeat for the next digit.

\n

Return a pqxx::zview. This is basically a std::string_view, but with one difference: when you create a zview you guarantee that there is a valid zero byte right after the string_view. The zero byte does not count as part of its size, but it has to be there.

This can be convenient when writing a field to an output stream. More importantly, it lets you write a field to e.g. a stringstream which you can then use to read, format and convert the field in ways that to() does not support.

\n

Example: parse a field into a variable of the nonstandard long long type.

long long L;

stringstream S;

Streams
\n
\n
\n

Most of the time it's fine to retrieve data from the database using SELECT queries, and store data using INSERT. But for those cases where efficiency matters, there are two data streaming mechanisms to help you do this more efficiently: \"streaming queries,\" for reading query results from the database; and the pqxx::stream_to class, for writing data from the client into a table.

\n

These are less flexible than SQL queries. Also, depending on your needs, it may be a problem to lose your connection while you're in mid-stream, not knowing that the query may not complete. But, you get some scalability and memory efficiencies in return.

\n

Just like regular querying, these streaming mechanisms do data conversion for you. You deal with the C++ data types, and the database deals with the SQL data types.

\n-

\n Interlude: null values

\n

So how do you deal with nulls? It depends on the C++ type you're using. Some types may have a built-in null value. For instance, if you have a char const * value and you convert it to an SQL string, then converting a nullptr will produce a NULL SQL value.

\n

But what do you do about C++ types which don't have a built-in null value, such as int? The trick is to wrap it in std::optional. The difference between int and std::optional<int> is that the former always has an int value, and the latter doesn't have to.

\n

Actually it's not just std::optional. You can do the same thing with std::unique_ptr or std::shared_ptr. A smart pointer is less efficient than std::optional in most situations because they allocate their value on the heap, but sometimes that's what you want in order to save moving or copying large values around.

\n

This part is not generic though. It won't work with just any smart-pointer type, just the ones which are explicitly supported: shared_ptr and unique_ptr. If you really need to, you can build support for additional wrappers and smart pointers by copying the implementation patterns from the existing smart-pointer support.

\n Streaming data <em>from a query</em>

\n

Use transaction_base::stream to read large amounts of data directly from the database. In terms of API it works just like transaction_base::query, but it's faster than the exec and query functions For larger data sets. Also, you won't need to keep your full result set in memory. That can really matter with larger data sets.

\n

Another performance advantage is that with a streaming query, you can start processing your data right after the first row of data comes in from the server. With exec() or query() you need to wait to receive all data, and only then can you begin processing. With streaming queries you can be processing data on the client side while the server is still sending you the rest.

\n

Not all kinds of queries will work in a stream. Internally the streams make use of PostgreSQL's COPY command, so see the PostgreSQL documentation for COPY for the exact limitations. Basic SELECT and UPDATE ... RETURNING queries will just work, but fancier constructs may not.

\n

As you read a row, the stream converts its fields to a tuple type containing the value types you ask for:

\n
for (auto [name, score] :
\n
tx.stream<std::string_view, int>("SELECT name, points FROM score")
\n
)
\n
process(name, score);
\n

On each iteration, the stream gives you a std::tuple of the column types you specify. It converts the row's fields (which internally arrive at the client in text format) to your chosen types.

\n

The auto [name, score] in the example is a structured binding which unpacks the tuple's fields into separate variables. If you prefer, you can choose to receive the tuple instead: for (std::tuple<int, std::string_view> :.

\n Is streaming right for my query?

\n

Here are the things you need to be aware of when deciding whether to stream a query, or just execute it normally.

\n

First, when you stream a query, there is no metadata describing how many rows it returned, what the columns are called, and so on. With a regular query you get a result object which contains this metadata as well as the data itself. If you absolutely need this metadata for a particular query, then that means you can't stream the query.

\n

Second, under the bonnet, streaming from a query uses a PostgreSQL-specific SQL command COPY (...) TO STDOUT. There are some limitations on what kinds of queries this command can handle. These limitations may change over time, so I won't describe them here. Instead, see PostgreSQL's COPY documentation for the details. (Look for the TO variant, with a query as the data source.)

\n

Third: when you stream a query, you start receiving and processing data before you even know whether you will receive all of the data. If you lose your connection to the database halfway through, you will have processed half your data, unaware that the query may never execute to completion. If this is a problem for your application, don't stream that query!

\n

The fourth and final factor is performance. If you're interested in streaming, obviously you care about this one.

\n

I can't tell you a priori whether streaming will make your query faster. It depends on how many rows you're retrieving, how much data there is in those rows, the speed of your network connection to the database, your client encoding, how much processing you do per row, and the details of the client-side system: hardware speed, CPU load, and available memory.
