Detailed Description

Constructor & Destructor Documentation

DatabaseSqlite::__construct ( $ params = null )

Constructor.

FIXME: It is possible to construct a Database object with no associated connection object, by specifying no parameters to __construct(). This feature is deprecated and should be removed.

DatabaseBase subclasses should not be constructed directly in external code. DatabaseBase::factory() should be used instead.

Parameters:

array $params Parameters passed from DatabaseBase::factory()

Reimplemented from DatabaseBase.

Definition at line 42 of file DatabaseSqlite.php.

References array(), attachDatabase(), global, DatabaseBase\isOpen(), open(), and wfDeprecated().

Member Function Documentation

DatabaseSqlite::addQuotes ( $ s )

Parameters:

Blob | string $s

Returns:: string

Reimplemented from DatabaseBase.

Definition at line 768 of file DatabaseSqlite.php.

References $s.

Referenced by strencode().

DatabaseSqlite::affectedRows ( )

Returns:: int

Implements DatabaseType.

Definition at line 442 of file DatabaseSqlite.php.

DatabaseSqlite::attachDatabase	(	$	name,
		$	file = `false`,
		$	fname = `__METHOD__`
	)

Attaches external database to our connection, see http://sqlite.org/lang_attach.html for details.

Parameters:

string	$name	Database name to be used in queries like SELECT foo FROM dbname.table
bool \| string	$file	Database file name. If omitted, will be generated using $name and $wgSQLiteDataDir
string	$fname	Calling function name

Returns:: ResultWrapper

Definition at line 225 of file DatabaseSqlite.php.

Referenced by __construct().

DatabaseSqlite::buildConcat ( $ stringList )

Build a concatenation list to feed into a SQL query.

Parameters:

string[] $stringList

Returns:: string

Reimplemented from DatabaseBase.

Definition at line 893 of file DatabaseSqlite.php.

DatabaseSqlite::buildGroupConcatField	(	$	delim,
		$	table,
		$	field,
		$	conds = `''`,
		$	join_conds = `array()`
	)

Build a GROUP_CONCAT or equivalent statement for a query.

This is useful for combining a field for several rows into a single string. NULL values will not appear in the output, duplicated values will appear, and the resulting delimiter-separated values have no defined sort order. Code using the results may need to use the PHP unique() or sort() methods.

Parameters:

string	$delim	Glue to bind the results together
string \| array	$table	Table name
string	$field	Field name
string \| array	$conds	Conditions
string \| array	$join_conds	Join conditions
