# NOTE: THESE TESTS CANNOT BE APPLIED TO TABLES OF TYPE MERGE.
#       Test which can be applied to MERGE tables should be stored in
#            include/ps_modify.inc .
#

#    
# NOTE: PLEASE SEE ps_1general.test (bottom) 
#       BEFORE ADDING NEW TEST CASES HERE !!!

#
# Please be aware, that this file will be sourced by several test case files
# stored within the subdirectory 't'. So every change here will affect 
# several test cases.
#
# Please do not modify the structure (DROP/ALTER..) of the tables
#     't1' and 't9'. 
#
# But you are encouraged to use these two tables within your statements
# (DELETE/UPDATE/...) whenever possible. 
#     t1   - very simple table
#     t9   - table with nearly all available column types
#
# The structure and the content of these tables can be found in
#     include/ps_create.inc  CREATE TABLE ...
#     include/ps_renew.inc   DELETE all rows and INSERT some rows
#
# Both tables are managed by the same storage engine.
# The type of the storage engine is stored in the variable '$type' . 



#------------------- Please insert your test cases here -------------------#
