# Test cases for bugs are added at the end. See template there.

# Tests that require --error go into sp-error.test

# Tests that check privilege and security issues go to sp-security.test.
# Tests that require multiple connections, except security/privilege tests,

# Tests that uses 'goto' to into sp-goto.test (currently disabled)
16 17
# Tests that destroys system tables (e.g. mysql.proc) for error testing

# Test cases for different combinations of condition handlers in nested
# begin-end blocks in stored procedures.
#
# Note that the standard specifies that the most specific handler should
# be triggered even if it's an outer handler masked by a less specific
# handler in an inner block.
# Note also that '02000' is more specific than NOT FOUND; there might be
# other '02xxx' states, even if we currently do not issue them in any
# situation (e.g. '02001').
#
# The combinations we test are these:
#
#                                         Inner
#              errcode      sqlstate     not found    sqlwarning   sqlexception
#  Outer      +------------+------------+------------+------------+------------+
#errcode      | h_ee (i)   | h_es (o)   | h_en (o)   | h_ew (o)   | h_ex (o)   |
#sqlstate     | h_se (i)   | h_ss (i)   | h_sn (o)   | h_sw (o)   | h_sx (o)   |
#not found    | h_ne (i)   | h_ns (i)   | h_nn (i)   |            |            |
#sqlwarning   | h_we (i)   | h_ws (i)   |            | h_ww (i)   |            |
#sqlexception | h_xe (i)   | h_xs (i)   |            |            | h_xx (i)   |
#             +------------+---------------------------------------------------+
#
# (i) means that the inner handler is the one that should be invoked,
# (o) means that the outer handler should be invoked.
#
# ('not found', 'sqlwarning' and 'sqlexception' are mutually exclusive, hence
#  no tests for those combinations.)

# BUG#4902: Stored procedure with SHOW WARNINGS leads to packet error
#
# Added tests for most other show commands we could find too.
# (Skipping those already tested, and the ones depending on optional handlers.)
#
# Note: This will return a large number of results of different formats,
#       which makes it impossible to filter with --replace_column.
#       It's possible that some of these are not deterministic across
#       platforms. If so, just remove the offending command.

# Bug#5967 "Stored procedure declared variable used instead of column"
# The bug should be fixed later.
# Test precedence of names of parameters, variable declarations, 
# variable declarations in nested compound statements, table columns,
# table columns in cursor declarations.
# According to the standard, table columns take precedence over
# variable declarations. In MySQL 5.0 it's vice versa.
