Question

how can I find the parameters(function declaration) of stored procedures in Informix?
whether “{ call sp_csq_activity }” or “{ call sp_csq_activity(?,? ..) }” and their types? And also is there any definitions list of this stored functions? How can I use these functions to retrieve any columns of a table in db?

public void callSP() throws SQLException {

        CallableStatement proc = null;

        proc = conn.prepareCall("{ call sp_csq_activity }");
        proc.execute();

    }

Answer 1

Use this : select * from sysprocedures
