################ 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.
DEALLOCATE PREPARE stmt ;

##### 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
#               t9 - 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 't9'.
#    include/ps_modify.inc  test cases with INSERT/UPDATE/... 
#                           These test cases should not modify the structure 
#                           (DROP/ALTER..) of the tables
#                           't1' and 't9'.
#         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 't9' .
#    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.
#
#     Matthias
