##### The basic functions ####
# 1. PREPARE stmt_name FROM <preparable statement>;
# <preparable statement> ::=
# 'literal_stmt' |
# @variable_ref_stmt.
# The statement may contain question marks as placeholders for parameters.
#
# Bind a statement name to a string containing a SQL statement and
# send it to the server. The server will parse the statement and
# reply with "Query Ok" or an error message.
#
PREPARE stmt FROM ' select * from t1 where a = ? ' ;
# 2. EXECUTE stmt_name [USING @var [, @var ]];
# Current values of supplied variables are used as parameters.
#
# Send the server the order to execute the statement and supply values
# for the input parameters needed.
# If no error occurs the server reply will be identical to the reply for
# the query used in PREPARE with question marks replaced with values of
# the input variables.
#
SET @var= 2 ;
EXECUTE stmt USING @var ;
# The non prepared statement with the same server reply would be:
select * from t1 where a = @var ;
# 3. DEALLOCATE PREPARE stmt_name;
#
# Send the server the order to drop the parse informations.
# The server will reply with "Query Ok" or an error message.

##### RULES OF THUMB TO PRESERVE THE SYSTEMATICS OF THE PS TEST CASES #####
#
# 0. You don't have the time to
# - read and pay attention to these rules of thumb
# - accept that QA may move your test case to a different place
# (I will not change your code!!) .
# Please append your test case to
# t/ps.test
#
# 1. You have more time and want to get as much value from you test case as
# possible. Please try to make the following decisions:
#
# Will the execution or result of the sub test case depend on the
# properties of a storage engine ?
#
# NO --> alter t/ps_1general.test (Example: Command with syntax error)
# If you need a table, please try to use
# t1 - very simple table
# t_many_col_types - table with nearly all available column types
# whenever possible.
#
# 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' . In ps_1general.test $type is set to 'MYISAM'.
#
# Please feel free to source ps_create.inc or ps_renew.inc
# whenever you think it helps. But please restore the original
# state of these tables after your tests, because the following
# statements may depend on it.
#
# YES
# |
# |
# Is it possible to apply the sub test case to all table types ?
# YES --> alter include/ps_query.inc (for SELECTs)
# include/ps_modify.inc (for INSERT/UPDATE/DELETE)
# include/ps_modify1.inc (also for INSERT/UPDATE/DELETE,
# but t/ps_5merge.test will not source that file)
# Please try to find an appropriate place within the file.
# It would be nice if we have some systematics in the
# order of the sub test cases (if possible).
#
# Please be aware, that
# include: ps_query.inc, ps_modify.inc, ps_modify1.inc
# will be sourced by several test case files stored within the
# subdirectory 't'. So every change here will affect several test
# cases.
#
# NO
# |
# |
# Append the sub test case to the appropriate
# ps_<number><table type>.test .
#
# 2. The current structure of the PS tests
#
# t/ps_1general.test Check of basic PS features, SHOW commands and DDL
# The tests should not depend on the table type.
#
# t/ps_2myisam Check of PS on tables of type MYISAM .
# t/ps_3innodb Check of PS on tables of type InnoDB .
# ...
# t/ps_6bdb Check of PS on tables of type BDB .
# All storage engine related tests use the variable $type to hold the
# name of the storage engine.
#
# include/ps_query.inc test cases with SELECT/...
# These test cases should not modify the content or
# the structure (DROP/ALTER..) of the tables
# 't1' and 't_many_col_types'.
# include/ps_modify.inc test cases with INSERT/UPDATE/...
# These test cases should not modify the structure
# (DROP/ALTER..) of the tables
# 't1' and 't_many_col_types'.
# These two test sequences will be applied to all table types .
#
# include/ps_modify1.inc test cases with INSERT/UPDATE/...
# This test sequences will be applied to all table types
# except MERGE tables.
#
# include/ps_create.inc DROP and CREATE of the tables
# 't1' and 't_many_col_types' .
# include/ps_renew.inc DELETE all rows and INSERT some rows, that means
# recreate the original content of these tables.
# Please do not alter the commands concerning these two tables.
#
# Please feel free and encouraged to exploit the current code sharing
# mechanism of the 'ps_<number><table type>' test cases. It is an convenient
# way to check all storage engines.
#
# Thank you for reading these rules of thumb.
#
