public function DatabaseConnection::prefixTables

Appends a database prefix to all tables in a query.

Queries sent to Backdrop should wrap all table names in curly brackets. This function searches for this syntax and adds Backdrop's table prefix to all tables, allowing Backdrop to coexist with other systems in the same database and/or schema if necessary.

Parameters

string $sql: A string containing a partial or entire SQL query.

Return value

string: The properly-prefixed string.
