Grant privileges on several tables with specific prefix

Question

I\'m using the table prefix method for having several clients use the same database. The number of tables created per client will be ~55. Instead of doing all of the grant

Answer 1

using bash:

mysql -Ne "show tables from test like 'foo_%'" | xargs -I {} mysql -Ne "GRANT SELECT ON test.{} TO 'foouser'@'%'"

Answer 2

I'm not sure if you can wildcard table names, you can definitely wildcard database names though. Watch out though as _ is a wildcard matching any single character (like . in a regular expression).

The Documention is here: http://dev.mysql.com/doc/refman/5.5/en/grant.html

The “_” and “%” wildcards are permitted when specifying database names in GRANT statements that grant privileges at the global or database levels. This means, for example, that if you want to use a “_” character as part of a database name, you should specify it as “\_” in the GRANT statement, to prevent the user from being able to access additional databases matching the wildcard pattern; for example, GRANT ... ON `foo\_bar`.* TO ....

Answer 3

The following

GRANT SELECT , INSERT , UPDATE , DELETE ON ``database.prefix\_%``. * TO 'username'@'localhost'

works fine (tested with MySQL 5.6.12 on Windows)

Answer 4

Advance Note: This is not my answer. I found it at http://lists.mysql.com/mysql/202610 and have copied and pasted for simplicity credit to Stephen Cook

You can use the INFORMATION_SCHEMA.TABLES view to generate the GRANT statements for you. Write a query along these lines:

SELECT   CONCAT('GRANT SELECT ON test.', TABLE_NAME, ' to ''foouser'';')
FROM     INFORMATION_SCHEMA.TABLES
WHERE    TABLE_SCHEMA = 'test'
      AND TABLE_NAME LIKE 'foo_%'

Then run it, copy the results, and run those results as a query or script. You can of course get as crazy as you want with this, for example if you do this for many users maybe write a stored procedure that takes a parameter for the username and can therefore be used as a tool whenever you need it.

It isn't a syntax you asked for, but it is a nice trick that works.

Replace the table schema 'test' with the name of your database. foo_% can be replaced with the appropraite prefix_%

I tried this on my own and it worked great.
