experts, I need to use case statement in an oracle where clause. My requirement is that I have 3 inputs to a procedure i_mlg, i_term, i_dctbl which can have values or can have a -1 in them.
If it has a -1 in any of them for ex: if i_term has a -1 then I need to select all the terms in the table column. If it has a specified number say 2, then I need to select the value for the term which corresponds to 2 in the term column in the table. Similarly I need to do it for i_dctbl and i_mlg. how can I achieve this in a single select statement.?
