# Bug#56632: ALTER TABLE implicitly changes ROW_FORMAT to COMPRESSED
# http://bugs.mysql.com/56632
#
# Innodb automatically uses compressed mode when the KEY_BLOCK_SIZE
# parameter is used, except if the ROW_FORMAT is also specified, in
# which case the KEY_BLOCK_SIZE is ignored and a warning is shown.
# But Innodb was getting confused when neither of those parameters
# was used on the ALTER statement after they were both used on the
# CREATE.
#
# This will test the results of all 4 combinations of these two
# parameters of the CREATE and ALTER.
#
# Tests 1-5 use INNODB_STRICT_MODE=1 which returns an error
# if there is anything wrong with the statement.
#
# 1) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
# Result; CREATE; fails with error ER_CANT_CREATE_TABLE
# 2) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
# Result; CREATE succeeds,
# ALTER quietly converts ROW_FORMAT to compressed.
# 3) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
# Result; CREATE quietly converts ROW_FORMAT to compressed,
# ALTER fails with error ER_CANT_CREATE_TABLE.
# 4) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
# Result; CREATE succeeds,
# ALTER; fails with error ER_CANT_CREATE_TABLE
# 5) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with neither.
# Result; CREATE; fails with error ER_CANT_CREATE_TABLE
#
# Tests 6-11 use INNODB_STRICT_MODE=0 which automatically makes
# adjustments if the prameters are incompatible.
#
# 6) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
# Result; CREATE succeeds, warns that KEY_BLOCK_SIZE is ignored.
# ALTER succeeds, no warnings.
# 7) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
# Result; CREATE succeeds,
# ALTER quietly converts ROW_FORMAT to compressed.
# 8) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
# Result; CREATE quietly converts ROW_FORMAT to compressed,
# ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
# 9) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
# Result; CREATE succeeds,
# ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
# 10) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with neither.
# Result; CREATE succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
# ALTER succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
# 11) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with ROW_FORMAT=COMPACT.
# Result; CREATE succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
# ALTER succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
# 12) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with KEY_BLOCK_SIZE=1.
# Result; CREATE succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
