RE: Function

OK, here it is:
I want to send the name of table and first column name and the valu of this column to the function and return the description for that value like this:

table1                              Values
col1 number(3)                          1
col2 varchar2(30)                               abc

f_get_desc('table1','col1',1) must return abc. THX -----Original Message-----

Hamid,

Could you explain, what are the parameters of your function, specifically: 'code_column_name' (is it column name?) and 'code_id'.
