Constructor & Destructor Documentation

__construct()

Wikimedia\Rdbms\Query::__construct	(	string	$sql,
			$flags,
			$queryVerb,
		?string	$writeTable = null,
			$cleanedSql = '' )

Parameters

string	$sql	SQL statement text
int	$flags	Bit field of ISQLPlatform::QUERY_CHANGE_* constants
string	$queryVerb	The first words of the SQL statement that convey what kind of database/table/column/index command was specified. Except for the cases listed in {

See also

MULTIWORD_VERBS}, this will be the first word of the SQL statement.

Parameters

string | null	$writeTable	The table targeted for writes, if any. Can be omitted if it would be hard to identify the table (e.g. when parsing an arbitrary SQL string).
string	$cleanedSql	Sanitized/simplified SQL statement text for logging. Typically, this means replacing variables / parameter values with placeholders. Can be omitted, in which case the code using the Query is responsible for sanitizing.
