Constructor & Destructor Documentation

◆ __construct()

Wikimedia\Rdbms\DatabaseMssql::__construct ( array $params )

Constructor and database handle and attempt to connect to the DB server.

IDatabase classes should not be constructed directly in external code. Database::factory() should be used instead.

Parameters

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

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 64 of file DatabaseMssql.php.

References $params.

Member Function Documentation

◆ addIdentifierQuotes()

Wikimedia\Rdbms\DatabaseMssql::addIdentifierQuotes ( $s )

Parameters

string $s

Returns: string

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 1095 of file DatabaseMssql.php.

References $s.

◆ addQuotes()

Wikimedia\Rdbms\DatabaseMssql::addQuotes ( $s )

Parameters

string | int | null | bool | Blob $s

Returns: string|int

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 1075 of file DatabaseMssql.php.

References $blob, and $s.

Referenced by Wikimedia\Rdbms\DatabaseMssql\insert().

◆ affectedRows()

Wikimedia\Rdbms\DatabaseMssql::affectedRows ( )

Returns: int

Implements Wikimedia\Rdbms\IDatabase.

Definition at line 356 of file DatabaseMssql.php.

References Wikimedia\Rdbms\DatabaseMssql\$mAffectedRows.

◆ buildConcat()

Wikimedia\Rdbms\DatabaseMssql::buildConcat ( $stringList )

Parameters

array $stringList

Returns: string

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 1177 of file DatabaseMssql.php.

◆ buildGroupConcatField()

Wikimedia\Rdbms\DatabaseMssql::buildGroupConcatField	(	$delim,
		$table,
		$field,
		$conds = `''`,
		$join_conds = `[]`
	)

Build a GROUP_CONCAT or equivalent statement for a query.

MS SQL doesn't have GROUP_CONCAT so we emulate it with other stuff (and boy is it nasty)

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

Returns: string SQL text

Since: 1.23

◆ delete()

Wikimedia\Rdbms\DatabaseMssql::delete	(	$table,
		$conds,
		$fname = `__METHOD__`
	)

DELETE query wrapper.

Parameters

string	$table	Table name
string \| array	$conds	Array of conditions. See $conds in IDatabase::select() for the format. Use $conds == "*" to delete all rows
string	$fname	Name of the calling function

Exceptions

◆ deleteJoin()

Wikimedia\Rdbms\DatabaseMssql::deleteJoin	(	$delTable,
		$joinTable,
		$delVar,
		$joinVar,

		$fname = `__METHOD__`
	)

DELETE where the condition is a join.

MySQL overrides this to use a multi-table DELETE syntax, in other databases we use sub-selects

For safety, an empty $conds will not delete everything. If you want to delete all rows where the join condition matches, set $conds='*'.

DO NOT put the join condition in $conds.

Parameters

string	$delTable	The table to delete from.
string	$joinTable	The other table.
string	$delVar	The variable to join on, in the first table.
string	$joinVar	The variable to join on, in the second table.
array	$conds	Condition array of field names mapped to variables, ANDed together in the WHERE clause
string	$fname	Calling function name (use METHOD) for logs/profiling
