Changing only table comments does not work.

Hi.
Changing only table comments does not work.
The alter statement is output, but there is no value.
Execution result.
ALTER TABLE
target_table
;
Is not it supposed to change table comments?
Thank you.
Hi @camcima.
Thank you for your reply.
A little time has passed, so memory is vague.
I will verify it so please take some time.
Hi @camcima.
I'm sorry that it takes time to verify.
"php -mysql-diff migrate" correctly output alter statements.
However, the content was not displayed in "php -mysql-diff diff".
► table "assign" has a different schema
Diff completed!
Verified in sql below.
a.sql
CREATE TABLE IF NOT EXISTS
assign
(
user_id
BIGINT UNSIGNED NOT NULL COMMENT 'ユーザID',
update_at
DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '最終更新日時',
create_at
DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '登録日時',
PRIMARY KEYuser_id
)
ENGINE = InnoDB
COMMENT = 'アサイン情報1';
b.sql
CREATE TABLE IF NOT EXISTS
assign
(
user_id
BIGINT UNSIGNED NOT NULL COMMENT 'ユーザID',
update_at
DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '最終更新日時',
create_at
DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '登録日時',
PRIMARY KEYuser_id
)
ENGINE = InnoDB
COMMENT = 'アサイン情報';
Thanks.
Hi.
I met similar case on PHP MySQL Diff 1.2.1 (installed from composer).
from.schema
CREATE TABLE
admin
(
admin_id
int(11) COMMENT 'Administrator ID'
);
to.schema
CREATE TABLE
admin
(
admin_id
int(11) COMMENT 'タ'
);
When column comment included some non-ascii charactor, the command returns like below:
FROM from.schema
TO to.schema▼ table "admin" is in the FROM database but not in the TO database
I guess it happens with charactor has 3rd byte(UTF-8) as 0xbf (i.e. 'タ'[E382BF] or 'み'[E381BF], etc).
I wonder, preg_match 'u'(PCRE_UTF8) pattern modifier fix this, but I'm not sure.
