GerhardHi all00:54

grassiHi there, I have a SQL question which I currently can't figure out myself by reading the fabulous manual.01:06
grassiI want to do something like:01:06
grassiSELECT01:06
grassiCASE WHEN last_buy < '2008.10.1' THEN '#'+customer_nr) ELSE customer_nr END as "customer code"01:06
grassiFROM customer_table01:06
grassiSo when a customer hasn't bought anything since Oct. 2008, the customer_nr gets a '#' added as a prefix... Is that possible?01:06

GerhardI have a customer that from time to time accidentally produces carthesian products over huge tables leading to enormous work files and crashing the DBMS. Any chance to "auto-abort" those SQLs?01:40
GerhardI suppose that cause of the carthesian products are ill-designed VDBA queries, Excel / ODBC, Crystal Reports...01:44
grantcGerhard: you can set io limits for queries02:10
Gerhardin CBF?02:11

GerhardThanks for the link. Must I set this with ingsetenv ING_SET ....  on the clients?02:14
Gerhardah, I see this can be defined in a central place:   http://docs.ingres.com/ingres/9.2/security-guide/4846-database-grant-examples02:16
