I would like to use mysqldump to get a copy of the code for a stored
procedure in a format that is similar to the code I used to create it.
The problem is that I'm blind and I have to listen to the code to debug
it. I think I have a file containing the code that I used to create the
stored procedure but I want to make absolutely sure.
This is what I've tried:
mysqldump --p --routines --no-create-info --no-data --no-create-db
--skip-opt --skip-comments --compatible=ansi --result=routines.sql
<database>
My problem is that generates a file with a lot of lines I don't
understand. for example:
/*!50003 CREATE*/ /*!50020 DEFINER=`root`@`localhost`*/ /*!50003
PROCEDURE `TIMETABLE_SYNC`()
That appears to be the line to create the stored procedure
'timetable_sync'. But what's with all the other stuff on that line? Can
i get rid of it?
As Claudio mentioned, those are version-sensitive comments. In order for
a MySQL server to not ignore the comment, it must be a version equal to
or greater than the value tagged in the comment.
For example, stored procedures did not exist before version 5.0.3 . So
all of the stored procedure will be enclosed with comments that look like
/*!50003 */
We enhanced the security of the stored procedures themselves by adding
the DEFINER= option to the definition. We did this in version 5.0.20.
That is why that part of the stored procedure was dumped using the
comment tags
/*!50020 */
Unfortunately, I have no way at this time to separate the
version-specific comments from the rest of the dump. Perhaps someone
better than I at using grep, sed, or awk could produce a script to strip
those comments and share with the list?
Yours,
