Hamid,
Your problem is in the first select statement's where clause. By enclosing
:table_name in single quotes it becomes the table name vs. the passed in
parameter. In a function this should be:
"WHERE TABLE_NAME = table_name AND COLUMN_ID = 2;"
Now your only problem is that Oracle and PL/SQL will probably mix up TABLE_NAME
and table_name. Could get a little messy. BTDT. Recommended solution is to
rename the local variable to user_table_name or something like that.

Hi list,
I have this function it's compile ok but doesn't return any value:
CREATE OR REPLACE function f_get_desc2
(table_name in varchar2,
code_column_name in varchar2,
code_id in varchar2)
return varchar2
is
return_desc varchar2 (100) ;
DESC_VAL VARCHAR2(100);
begin
SELECT COLUMN_NAME INTO DESC_VAL FROM USER_TAB_COLUMNS ?????
WHERE TABLE_NAME =':table_name' AND COLUMN_ID = 2 ; ????
-- here I want to get the description column name from
user)tab_columns.....then get the value based on the ID
execute immediate 'select ' || DESC_VAL ||
' from ' || table_name || ' where ' || code_column_name ||
' = :id' into return_desc using code_id ;
return return_desc ;
end ;
/
I pass column_name ,code & value of the code to function then get the name
of description Column from table_name and finally get the description based
on table_name,descripton column & value, BUT doesn't return any value
I am not sure but the ?mark lines doesn't return any value.
Thanks for your help.
