#
# 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 -------------------#
