In collaboration with Sergey Vojtovich <svoj@mariadb.org>
The COMPRESSED clause is now a part of the data type and goes immediately
after the data type and length, but before the CHARACTER SET clause,
and before column attributes such as DEFAULT, COLLATE, ON UPDATE,
SYSTEM VERSIONING, engine specific column attributes.
In the old reduction, the COMPRESSED clause was a column attribute.
New syntax:
<varchar or text data type> <length> <compression> <character set> <column attributes>
<varbinary or blob data type> <length> <compression> <column attributes>
New syntax examples:
VARCHAR(1000) COMPRESSED CHARACTER SET latin1 DEFAULT ''
BLOB COMPRESSED DEFAULT ''
Deprecate syntax examples:
VARCHAR(1000) CHARACTER SET latin1 COMPRESSED DEFAULT ''
TEXT CHARACTER SET latin1 DEFAULT '' COMPRESSED
VARBINARY(1000) DEFAULT '' COMPRESSED
As a side effect:
- COMPRESSED is not valid as an SP label name in SQL/PSM routines any more
(but it's still valid as an SP label name in sql_mode=ORACLE)
- COMPRESSED is now allowed in combination with GENERATED ALWAYS AS:
TEXT COMPRESSED GENERATED ALWAYS AS REPEAT('a',1000)

# mysqldump_restore.test
|
|
#
|
|
# Purpose: Tests if mysqldump output can be used to successfully restore
|
|
# tables and data.
|
|
# We CREATE a table, mysqldump it to a file, ALTER the original
|
|
# table's name, recreate the table from the mysqldump file, then
|
|
# utilize include/diff_tables to compare the original and recreated
|
|
# tables.
|
|
#
|
|
# We use several examples from mysqldump.test here and include
|
|
# the relevant bug numbers and headers from that test.
|
|
#
|
|
# NOTE: This test is not currently complete and offers only basic
|
|
# cases of mysqldump output being restored.
|
|
# Also, does NOT work with -X (xml) output!
