# APSW Module

The module is the main interface to SQLite. Methods and data on the module have process wide effects.

## Type Annotations

Comprehensive `type annotations` are included, and your code can be checked by your editor or tools like mypy. You can refer to the types below for your annotations (eg as `apsw.SQLiteValue`)

Your source files should include:

    from __future__ import annotations

Note

These types are not available at run time, and have no effect when your code is running. They are only referenced when running a type checker, or using an IDE.

You will require a recent version of Python to use the type annotations.

class apsw.SQLiteValue
  `None`​ | `int`​ | `float`​ | `Buffer`​ | `str`​

  SQLite supports 5 types - `None`​ (NULL), 64 bit signed `int`​, 64 bit `float`​, `bytes`​ (`Buffer`​), and `str`​ (unicode text)

## API Reference

apsw.SQLITE_VERSION_NUMBER: int

  The integer version number of SQLite that APSW was compiled against. For example SQLite 3.44.1 will have the value 3440100. This number may be different than the actual library in use if the library is shared and has been updated. Call `sqlite_lib_version()` to get the actual library version.

apsw.allow_missing_dict_bindings(value: bool) → bool

  Changes how missing bindings are handled when using a `dict`. Historically missing bindings were treated as None. It was anticipated that dict bindings would be used when there were lots of columns, so having missing ones defaulting to None was convenient.

  Unfortunately this also has the side effect of not catching typos and similar issues.

  APSW 3.41.0.0 changed the default so that missing dict entries will result in an exception. Call this with True to restore the earlier behaviour, and False to have an exception.

  The previous value is returned.

apsw.apsw_version() → str

  Returns the APSW version.

apsw.compile_options: tuple[str, ...]

  A tuple of the options used to compile SQLite. For example it will be something like this, but with around 50 entries:

      ('ENABLE_LOCKING_STYLE=0', 'TEMP_STORE=1', 'THREADSAFE=1', 'ENABLE_FTS5',
       'OMIT_SHARED_CACHE', 'SYSTEM_MALLOC')

  Calls: sqlite3_compileoption_get

apsw.complete(statement: str) → bool

  Returns True if the input string comprises one or more complete SQL statements by looking for an unquoted trailing semi-colon. It does not consider comments or blank lines to be complete.

  An example use would be if you were prompting the user for SQL statements and needed to know if you had a whole statement, or needed to ask for another line:

      statement = input("SQL> ")
      while not apsw.complete(statement):
         more = input("  .. ")
         statement = statement + "\\n" + more

  Calls: sqlite3_complete

apsw.config(op: int, *args: Any) → None
  Parameters:

    - op – A configuration operation

    - args – Zero or more arguments as appropriate for op

  Some operations don’t make sense from a Python program. All the remaining are supported.

  Calls: sqlite3_config

apsw.connection_hooks: list[Callable[[Connection], None]]

  The purpose of the hooks is to allow the easy registration of `functions`, virtual tables or similar items with each `Connection` as it is created. The default value is an empty list. Whenever a Connection is created, each item in apsw.connection_hooks is invoked with a single parameter being the new Connection object. If the hook raises an exception then the creation of the Connection fails.

apsw.connections() → list[Connection]

  Returns a list of the connections

apsw.enable_shared_cache(enable: bool) → None

  Discouraged.

  Calls: sqlite3_enable_shared_cache

apsw.exception_for(code: int) → Exception

  If you would like to raise an exception that corresponds to a particular SQLite error code then call this function. It also understands extended error codes.

  For example to raise SQLITE_IOERR_ACCESS:

      raise apsw.exception_for(apsw.SQLITE_IOERR_ACCESS)

apsw.fork_checker() → None

  Note This method is not available on Windows as it does not support the fork system call.

  SQLite does not allow the use of database connections across forked processes (see the SQLite FAQ Q6). (Forking creates a child process that is a duplicate of the parent including the state of all data structures in the program. If you do this to SQLite then parent and child would both consider themselves owners of open databases and silently corrupt each other’s work and interfere with each other’s locks.)

  One example of how you may end up using fork is if you use the `multiprocessing module` which can use fork to make child processes.

  If you do use fork or multiprocessing on a platform that supports fork then you must ensure database connections and their objects (cursors, backup, blobs etc) are not used in the parent process, or are all closed before calling fork or starting a Process. (Note you must call close to ensure the underlying SQLite objects are closed. It is also a good idea to call `gc.collect(2)` to ensure anything you may have missed is also deallocated.)

  Once you run this method, extra checking code is inserted into SQLite’s mutex operations (at a very small performance penalty) that verifies objects are not used across processes. You will get a `ForkingViolationError` if you do so. Note that due to the way Python’s internals work, the exception will be delivered to `sys.excepthook()` in addition to the normal exception mechanisms and may be reported by Python after the line where the issue actually arose. (Destructors of objects you didn’t close also run between lines.)

  You should only call this method as the first line after importing APSW, as it has to shutdown and re-initialize SQLite. If you have any SQLite objects already allocated when calling the method then the program will later crash. The recommended use is to use the fork checking as part of your test suite.

apsw.format_sql_value(value: SQLiteValue) → str

  Returns a Python string representing the supplied value in SQLite syntax.

  Note that SQLite represents floating point Nan as `NULL`, infinity as `9e999` and loses the sign on negative zero.

apsw.hard_heap_limit(limit: int) → int

  Enforces SQLite keeping memory usage below limit bytes and returns the previous limit.

  See also

  `soft_heap_limit()`

  Calls: sqlite3_hard_heap_limit64

apsw.initialize() → None

  It is unlikely you will want to call this method as SQLite automatically initializes.

  Calls: sqlite3_initialize

apsw.keywords: set[str]

  A set containing every SQLite keyword

  Calls:

    - sqlite3_keyword_count

    - sqlite3_keyword_name

apsw.log(errorcode: int, message: str) → None

  Calls the SQLite logging interface. You must format the message before passing it to this method:

      apsw.log(apsw.SQLITE_NOMEM, f"Need { needed } bytes of memory")

  Calls: sqlite3_log

apsw.memory_high_water(reset: bool = False) → int

  Returns the maximum amount of memory SQLite has used. If reset is True then the high water mark is reset to the current value.

  See also

  `status()`

  Calls: sqlite3_memory_highwater

apsw.memory_used() → int

  Returns the amount of memory SQLite is currently using.

  See also

  `status()`

  Calls: sqlite3_memory_used

apsw.no_change: object

  A sentinel value used to indicate no change in a value when used with `VTCursor.ColumnNoChange()`, `VTTable.UpdateChangeRow()`, `TableChange.new`, and `PreUpdate.update`.

apsw.pyobject(object: Any)

  Indicates a Python object is being provided as a runtime value.

apsw.randomness(amount: int) → bytes

  Gets random data from SQLite’s random number generator.

  Parameters:

    amount – How many bytes to return

  Calls: sqlite3_randomness

apsw.release_memory(amount: int) → int

  Requests SQLite try to free amount bytes of memory. Returns how many bytes were freed.

  Calls: sqlite3_release_memory

apsw.set_default_vfs(name: str) → None

  Sets the default vfs to name which must be an existing vfs. See `vfs_names()`.

  Calls:

    - sqlite3_vfs_register

    - sqlite3_vfs_find

apsw.shutdown() → None

  It is unlikely you will want to call this method and there is no need to do so. It is a really bad idea to call it unless you are absolutely sure all `connections`, `blobs`, `cursors`, `vfs` etc have been closed, deleted and garbage collected.

  Calls: sqlite3_shutdown

apsw.sleep(milliseconds: int) → int

  Sleep for at least the number of milliseconds, returning how many milliseconds were requested from the operating system.

  Calls: sqlite3_sleep

apsw.soft_heap_limit(limit: int) → int

  Requests SQLite try to keep memory usage below limit bytes and returns the previous limit.

  See also

  `hard_heap_limit()`

  Calls: sqlite3_soft_heap_limit64

apsw.sqlite3_sourceid() → str

  Returns the exact checkin information for the SQLite 3 source being used.

  Calls: sqlite3_sourceid

apsw.sqlite_lib_version() → str

  Returns the version of the SQLite library. This value is queried at run time from the library so if you use shared libraries it will be the version in the shared library.

  Calls: sqlite3_libversion

apsw.status(op: int, reset: bool = False) → tuple[int, int]

  Returns current and highwater measurements.

  Parameters:

    - op – A status parameter

    - reset – If True then the highwater is set to the current value

  Returns:

    A tuple of current value and highwater value

  See also

  - `Connection.status()` for statistics about a `Connection`

apsw.using_amalgamation: bool

  If True then SQLite amalgamation is in use (statically compiled into APSW). Using the amalgamation means that SQLite shared libraries are not used and will not affect your code.

apsw.vfs_details() → list[dict[str, int | str]]

Returns a list with details of each vfs. The detail is a dictionary with the keys being the names of the sqlite3_vfs data structure, and their corresponding values.

Pointers are converted using `PyLong_FromVoidPtr()`.

Calls: sqlite3_vfs_find

apsw.vfs_names() → list[str]

  Returns a list of the currently installed vfs. The first item in the list is the default vfs.

  Calls: sqlite3_vfs_find

## SQLite constants

SQLite has many constants used in various interfaces. To use a constant such as SQLITE_OK, just use `apsw.SQLITE_OK`.

The same values can be used in different contexts. For example SQLITE_OK and SQLITE_CREATE_INDEX both have a value of zero. For each group of constants there is also a mapping (dict) available that you can supply a string to and get the corresponding numeric value, or supply a numeric value and get the corresponding string. These can help improve diagnostics/logging, calling other modules etc. For example:

    apsw.mapping_authorizer_function["SQLITE_READ"] == 20
    apsw.mapping_authorizer_function[20] == "SQLITE_READ"
