#
|
|
# Testing the behavior of 'PREPARE', 'DDL', 'EXECUTE' scenarios
|
|
#
|
|
# Background:
|
|
# In a statement like "select * from t1", t1 can be:
|
|
# - nothing (the table does not exist)
|
|
# - a real table
|
|
# - a temporary table
|
|
# - a view
|
|
#
|
|
# Changing the nature of "t1" between a PREPARE and an EXECUTE
|
|
# can invalidate the internal state of a prepared statement, so that,
|
|
# during the execute, the server should:
|
|
# - detect state changes and fail to execute a statement,
|
|
# instead of crashing the server or returning wrong results
|
|
# - "RE-PREPARE" the statement to restore a valid internal state.
|
|
#
|
|
# Also, changing the physical structure of "t1", by:
|
|
# - changing the definition of t1 itself (DDL on tables, views)
|
|
# - changing TRIGGERs associated with a table
|
|
# - changing PROCEDURE, FUNCTION referenced by a TRIGGER body,
|
|
# - changing PROCEDURE, FUNCTION referenced by a VIEW body,
|
|
# impacts the internal structure of a prepared statement, and should
|
|
# cause the same verifications at execute time to be performed.
|
|
#
|
|
# This test provided in this file cover the different state transitions
|
|
# between a PREPARE and an EXECUTE, and are organized as follows:
|
|
# - Part 1: NOTHING -> TABLE
|
|
# - Part 2: NOTHING -> TEMPORARY TABLE
|
|
# - Part 3: NOTHING -> VIEW
|
|
# - Part 4: TABLE -> NOTHING
|
|
# - Part 5: TABLE -> TABLE (DDL)
|
|
# - Part 6: TABLE -> TABLE (TRIGGER)
|
|
# - Part 7: TABLE -> TABLE (TRIGGER dependencies)
|
|
# - Part 8: TABLE -> TEMPORARY TABLE
|
|
# - Part 9: TABLE -> VIEW
|
|
# - Part 10: TEMPORARY TABLE -> NOTHING
|
|
# - Part 11: TEMPORARY TABLE -> TABLE
|
|
# - Part 12: TEMPORARY TABLE -> TEMPORARY TABLE (DDL)
|
|
# - Part 13: TEMPORARY TABLE -> VIEW
|
|
# - Part 14: VIEW -> NOTHING
|
|
# - Part 15: VIEW -> TABLE
|
|
# - Part 16: VIEW -> TEMPORARY TABLE
|
|
# - Part 17: VIEW -> VIEW (DDL)
|
|
# - Part 18: VIEW -> VIEW (VIEW dependencies)
|
|
# - Part 19: Special tables (INFORMATION_SCHEMA)
|
|
# - Part 20: Special tables (log tables)
|
|
# - Part 21: Special tables (system tables)
|
|
# - Part 22: Special tables (views temp tables)
|
|
# - Part 23: Special statements
|
|
# - Part 24: Testing the strength of TABLE_SHARE version
