DatabaseMssql::addIdentifierQuotes ( $ s )

Parameters:

string $s

Returns:: string

Reimplemented from DatabaseBase.

Definition at line 1154 of file DatabaseMssql.php.

DatabaseMssql::addQuotes ( $ s )

Parameters:

string $s

Returns:: string

Reimplemented from DatabaseBase.

Referenced by insert(), and makeList().

DatabaseMssql::affectedRows ( )

Returns:: int

Implements DatabaseType.

Definition at line 365 of file DatabaseMssql.php.

DatabaseMssql::buildConcat ( $ stringList )

Parameters:

array $stringList

Returns:: string

Reimplemented from DatabaseBase.

Definition at line 1226 of file DatabaseMssql.php.

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

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

Reimplemented from DatabaseBase.

Definition at line 1247 of file DatabaseMssql.php.

DatabaseMssql::cascadingDeletes ( )

Returns true if this database supports (and uses) cascading deletes.

Returns:: bool

Reimplemented from DatabaseBase.

Definition at line 44 of file DatabaseMssql.php.

DatabaseMssql::cleanupTriggers ( )

Returns true if this database supports (and uses) triggers (e.g.

on the page table)

Returns:: bool

Reimplemented from DatabaseBase.

Definition at line 48 of file DatabaseMssql.php.

DatabaseMssql::closeConnection ( ) [protected]

Closes a database connection, if it is open Returns success, true if already closed.

Returns:: bool

Reimplemented from DatabaseBase.

Definition at line 140 of file DatabaseMssql.php.

DatabaseMssql::dataSeek	(	$	res,
		$	row
	)

Parameters:

MssqlResultWrapper	$res
int	$row

Returns:: bool

Implements DatabaseType.

Definition at line 321 of file DatabaseMssql.php.

References $res.

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

DELETE query wrapper.

Parameters:

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

Exceptions:

DBUnexpectedError

Returns:: bool|ResultWrapper

Reimplemented from DatabaseBase.

		$	joinTable,
		$	delVar,
		$	joinVar,
		$	conds,
		$	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

Exceptions:
