DatabaseTestHelper::query	(		$sql,
			$fname = '',
			$tempIgnore = false
	)

Run an SQL query and return the result.

Normally throws a DBQueryError on failure. If errors are ignored, returns false instead.

In new code, the query wrappers select(), insert(), update(), delete(), etc. should be used where possible, since they give much better DBMS independence and automatically quote or validate user input in a variety of contexts. This function is generally only useful for queries which are explicitly DBMS-dependent and are unsupported by the query wrappers, such as CREATE TABLE.

However, the query wrappers themselves should call this function.

Parameters

string	$sql	SQL query
string	$fname	Name of the calling function, for profiling/SHOW PROCESSLIST comment (you can use METHOD or add some extra info)
bool	$tempIgnore	Whether to avoid throwing an exception on errors... maybe best to catch the exception instead?

Exceptions

MWException

Returns

bool|ResultWrapper True for a successful write query, ResultWrapper object for a successful read query, or false on failure if $tempIgnore set
