# The include statement below is a temp one for tests that are yet to #be ported to run with InnoDB, #but needs to be kept for tests that would need MyISAM in future. --source include/force_myisam_default.inc ############################################################## # Purpose: To test DICTionary changes while executing # SPJ (Pushed join) operations. # SPJ block should take part in the dictionary update # loop controlled by DICT. Alter /dropping a table # while there are ongoing SPJ operations should cause # these operations to be terminated. # ############################################################## ############################################################## # NOTE ABOUT TESTING BELOW: # # Test cases are expected to terminate query execution on SPJ # when a (SPJ-) dictionary change are detected. The error codes # 20019-20021 are returned from SPJ, which are mapped to either # ER_NO_SUCH_TABLE, or ER_TABLE_DEF_CHANGED. # # To allow for possible race between DML and DDL queries, # (Didn't start, or completed before the other), 'error 0' # is also allowed as an outcome from these tests. # # '--replace_column 10 ### 11 ###' is used for explains throughout # the test as experience has shown that 'rows' estimates # may vary depending on OS, compiler and .. phase of moon. # ############################################################## --source include/not_embedded.inc --source include/have_multi_ndb.inc connect (ddl,localhost,root,,test); connection ddl; use test; ## Initially create as MyISAM to avoid 'Out of operation records' ## ...
