- #
- # 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 (INSERT/UPDATE/DELETE) the content or the
- # structure (DROP/ALTER..) of the tables
- # 't1' and 't9'.
- # Such tests should be done in include/ps_modify.inc .
- #
- # But you are encouraged to use these two tables within your SELECT statements
- # 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 -------------------#
- #-------- Please be very carefull when editing behind this line ----------#
