Re: Getting conditions in a SELECT query

Hi Piotr!

The COND *cond is a sub-tree of the item tree that represents the query plan. To analyze it you need to traverse the tree using the Item::traverse_cond method. The only example of how this can be done is in the ndbcluster handler, see sql/ha_ndbcluster_cond.cc. There is no text representation of the condition. The complete query can be found in current_thd->query.
