Constructor & Destructor Documentation

__construct()

Wikimedia\Rdbms\RawSQLValue::__construct

(

string

$value

)

This should be used very rarely and NEVER with user input.

Most common usecases is the value in a SET clause of UPDATE, e.g. for updates like total_pages = total_pages + 1:

$queryBuilder->set( [ 'total_pages' => new RawSQLValue( 'total_pages + 1' ) ] )

…or as one side of a comparison in a WHERE condition, e.g. for conditions like range_start = range_end, range_start != range_end:

$queryBuilder->where( [ 'range_start' => new RawSQLValue( 'range_end' ) ] ) $queryBuilder->where( $db->expr( 'range_start', '!=', new RawSQLValue( 'range_end' ) ) )

(When all values are literals, consider whether using RawSQLExpression is more readable.)

Parameters
