revno: 2630.2.6
committer: Konstantin Osipov <konstantin@mysql.com>
branch nick: mysql-6.0-27430
timestamp: Mon 2008-05-26 16:12:28 +0400
message:
  Cover four special cases of WL#4166 with tests:
  - when the query cache is disabled at the time of prepared statement
  reprepare
  - when long data parameters are used
  - when character_set_connection != character_set_client, and a parameter
  conversion takes place
  - when parameter data is out of acceptable range, e.g. year 10000 is
  supplied as part of MYSQL_TYPE_DATETIME value. The server is supposed
  to warn in such case.

# This is to see how statements prepared via the PREPARE SQL command
# go into the query cache: if using parameters they cannot; if not
# using parameters they can.
# go into the query cache.
# Query cache is abbreviated as "QC"
#
# Last update:
# 2008-05-26 Kostja
# - Add test coverage for automatic statement reprepare
#
# 2007-05-03 ML - Move t/query_cache_sql_prepare.test
# to include/query_cache_sql_prepare.inc
# - Create two toplevel tests sourcing this routine
