When I have a sql statement like select * from table1
, it works great, but as soon as I put it into a function, I get:
ORA-00942: table or view does not exist
How to solve this?
There's a strong chance that the privileges to select from table1 have been granted to a role, and the role has been granted to you. Privileges granted to a role are not available to PL/SQL written by a user, even if the user has been granted the role.
You see this a lot for users that have been granted the dba role on objects owned by sys. A user with dba role will be able to, say, SELECT * from V$SESSION
, but will not be able to write a function that includes SELECT * FROM V$SESSION
.
The fix is to grant explicit permissions on the object in question to the user directly, for example, in the case above, the SYS user has to GRANT SELECT ON V_$SESSION TO MyUser;
