Re: Decimal Mapping problem
: Try to cast MySQL decimal data type to string, i.e. : : CAST( IF(drt.discount IS NULL,'0',(drt.discount/100)) AS CHAR) as discount : (or CAST AS TEXT) ...to clarify here, the values you are seeing are what happens when the DB returns to DIH a value in a type it doesn't udnerstand -- in this case it's a byte array. DIH isn't sure what do do with this byte array, so it just calls the java toString() method on it. casting that byte array to something DIH understands (like a string) is one way to solve the problem, but the other would be to use some SQL expression that always returns aconsistent type, so the SQL server knows what type to declare in it's response -- in your example you are sometimes returning a string (if NULL, you return the string '0') and sometimes returning a number (if not null, drt.discount/100) use SQL that alwasy returns a number, and this problem will also go away. -Hoss
