Fix for ORDER BY handling in GROUP_CONCAT()
WL#1246 (Query cache in embedded library)
Some fixes after testing
libmysqld/emb_qcache.cc:
code added to check if the recordset has no rows
sql/sql_cache.cc:
this code should not work if the query isn't cacheable
WL#1246 (Query cache in embedded library)
libmysqld/Makefile.am:
New files added to the project
libmysqld/lib_sql.cc:
added initialization of 'newborn' fields:
catalog, catalog_length, def_length
sql/sql_cache.cc:
Code added to provide query-cache in embedded library
query_cache_insert isn't called during the query execution
in embedded library. So we call it in query_cache_end_of_result.
Parameter of query_cache_end_of_result changed to get access to
the recordset
sql/sql_cache.h:
function's parameter changed
sql/sql_parse.cc:
we don't need these anymore
