function db_query_temporary

Executes a SELECT query string and saves the result set to a temporary table.

The execution of the query string happens against the active database.

Parameters

string $query: The prepared SELECT statement query to run. Although it will accept both named and unnamed placeholders, named placeholders are strongly preferred as they are more self-documenting.

array $args: An array of values to substitute into the query. If the query uses named placeholders, this is an associative array in any order. If the query uses unnamed placeholders (?), this is an indexed array and the order must match the order of placeholders in the query string.

array $options: An array of options to control how the query operates.

Return value

string The name of the temporary table.
