Searching MySQL
Is there a query I can run to search all tables in a database for a particular string?
Something like this: select * from * where * like '%mysearchstring%'
Thanks.

No - unfortunatley there is not
If you are using mysql v 5.0 + you potentially could create a function to do this for you - using the information schema to find all tables, then all columns and then search each for your particular value - but this would be very slow - difficult and hard to show the results.

What about searching just one table? Is that not possible either? It is MySQL 5 I have.
For all your fields - if they are string fields you could do
Select

sorry pressed enter too quickly

If it's something used every so often, do a text search on your backups (take your backups using mysqldump)

I think Sheeri's point was if this is something used just for an occasional diagnostic by an admin, then taking a mysqldump of the database and searchingi that would be less trouble than a manual query through every column in every table. I'd have to agree.
Certainly if this is functionality end users need, then the solution should be kept within the DBMS.

Hey,
I would take a look at http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html for a great list of examples of different database/table structures you can use on a "tagging" based system - although this kind of structure can be adapted for other uses also. I wouldn't recommend "MySQLicious" solution (like "%text%").

"%text%" is not "MySQLicious" -- all the database vendors have LIKE and allow wildcards -- just to be clear for the people reading this.

Also, http://firestuff.org/wordpress/2006/07/20/sqlsearch-100/ might be useful -- InnoDB fulltext search that supports multi-column indexes.
Sheeri, "MySQLicious" is just a name for a database structure for mirroring del.icio.us bookmarks, which un-surprisingly the project is also called "MySQLicious" - hence the name "MySQLicious". I did not mention that MySQLicious is some kind of strange addon for MySQL. Nor did I imply that the LIKE operator is not available, or used in other database engines. So I don't see what exactly you are 'clearing' up.

ah, sorry. I hadn't realized it was an actual tool.
