Function find_partial_select_handler

sql/sql_select.cc:5300–5305

Wrapper for find_select_handler_inner() for the case of partial select pushdown. Partial pushdown means that a unit (i.e. multiple selects combined with UNION/EXCEPT/INTERSECT operators) cannot be pushed down to the storage engine as a whole but some particular selects of this unit can. For example, SELECT a FROM federated.t1 -- can be pushed down to Federated UNION SELECT b F
