Question

Negative restrictions in MySQL 4.1.22?

Asked by: x_terminat_or_3

Hi

This might be a though nut to crack. . .

Our <application>, mostly PHP based, uses a single MySQL user account to both read and write data to our master database server, which in turn sends it to its slaves, you know, your standard replication setup.

Now, I have some tables I want to restrict write access to, but the MySQL user automatically has access to everything because of its GRANT ALL ON *.*  TO user@host  privilege.

I have thought about chmod-ing the table, but it isn't very practical since it is on a different server.

The other option, defining privileges of each of the 20K+ tables in our databases is not only very daunting, but we'd need to employ an extra hand just to maintain those privs, that, and they don't work very well with temporary tables (with uniqid names)

So, is there a way to do in MySQL

GRANT ALL ON *.* EXCEPT thisorthadatabas TO user@...

Or another way you can think of revoking write privilege to the user for this particular database.


Thank you.

All REVOKE does is take privileges away, what I want is exceptions to global privileges, like if a user has a global update priv, I want it to exclude access to a certain database.

I'm afraid this can't be done as far as I know. Global privileges (table: mysql.user) take precedence over the DB privileges (table: mysql.db)...

Any other ideas on thow to do this?, maybe not with SQL language, but with another means?

Well, it's not an SQL problem - it's just the way MySQL privileges work :( Sorry :(
