db2 忽略 where 子句中的大小写

Question

Normally we perform the ignore case as follow:

select * from user where UPPER(username) = UPPER('maker1');

Is this any way to do it in where clause condition?

I understand that we can do as follow:

select * from user where UPPER(username) in ( UPPER('maker1'), UPPER(maker2) );

But how about do it in preparedStatement ?

For example:

sb.append( "AND functionType IN (:functionType) " );
        map.put( "functionType",
                command.getListValues( command.getAllNonTradeFunctionsList( ) ) );
    query.setProperties( map );

what is the issue you are facing here is the simple example demonstrating your problem

String query = 
                "SELECT agent.familyname, agent.givenname"
                + " FROM agent"
                + " WHERE agent.agentid = ?"
                + " AND (" 
                + " familyname ilike ? OR givenname ilike ?" 
                + ") " 
                + " ORDER by familyname";


        pst.setInt(1, piececreation.agentid);
        pst.setString(2, agent_lastname.toLowerCase());
        pst.setString(3, agent_name.toLowerCase());

let't me know if any other help needed
