◆ limitResult()

DatabasePostgres::limitResult	(	$sql,

If $offset is provided as well, then the first $offset rows should be discarded, and the next $limit rows should be returned. If the result of the query is not ordered, then the rows to be returned are theoretically arbitrary.

$sql is expected to be a SELECT, if that makes a difference.

The version provided by default works in MySQL and SQLite. It will very likely need to be overridden for most other DBMSes.

Parameters

string	$sql	SQL query we will append the limit too
int	$limit	The SQL limit
int \| bool	$offset	The SQL offset (default false)

◆ selectDB()

DatabasePostgres::selectDB ( $db )

Postgres doesn't support selectDB in the same way MySQL does.

So if the DB name doesn't match the open connection, open a new one

Parameters

string $db

Returns: bool

Reimplemented from DatabaseBase.

Definition at line 426 of file DatabasePostgres.php.

◆ selectSQLText()

DatabasePostgres::selectSQLText	(	$table,
		$vars,
		$conds = `''`,
		$fname = `__METHOD__`,
		$options = `array()`,
		$join_conds = `array()`
	)

Change the FOR UPDATE option as necessary based on the join conditions.

Then pass to the parent function to get the actual SQL text.

In Postgres when using FOR UPDATE, only the main table and tables that are inner joined can be locked. That means tables in an outer join cannot be FOR UPDATE locked. Trying to do so causes a DB error. This wrapper checks which tables can be locked and adjusts it accordingly.

MySQL uses "ORDER BY NULL" as an optimization hint, but that syntax is illegal in PostgreSQL.

◆ tableName()

DatabasePostgres::tableName	(	$name,

All functions of this object which require a table name call this function themselves. Pass the canonical name to such functions. This is only needed when calling query() directly.

Parameters

string	$name	Database table name
string	$format	One of: quoted - Automatically pass the table name through addIdentifierQuotes() so that it can be used in a query. raw - Do not add identifier quotes to the table name

Returns: string Full database name
