get_extra_joins

(

)

Return an array 'table_alias' => 'JOIN clause' to bring in any data that this column required.

The return values for all the columns will be checked. It is OK if two columns join in the same table with the same alias and identical JOIN clauses. If to columns try to use the same alias with different joins, you get an error. The only table included by default is the question table, which is aliased to 'q'.

It is importnat that your join simply adds additional data (or NULLs) to the existing rows of the query. It must not cause additional rows.

Returns:

array 'table_alias' => 'JOIN clause'
