+# 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' .
+
