ORACLE PL/SQL: Table or view does not exist

Question

I'd appreciate some help on this topic since I am making my first steps into PL/SQL:

When trying to create a function, I get an error: "Table or view does not exist" for all 5 Select statements (and for the statement in the cursor declaration as well). I am sure all tables exist.

Many thanks in advance.

Answer 1

I assume the table belong to another schema than the schema into which your function is compiled. If you have granted select on these table via role rather than directly, Oracle will give you an ORA-00942.

See this stackoverflow question for more information.

Answer 2

Did you compile the procedure on the same schema of the tables? If you use toad try to press F4 button when cursor is on table name or try to launch the command "desc tablename"

Answer 3

Try describing the tablename with same credentials in the same schema with which you are trying to compile/execute the function.

desc tablename
