The POSITION, LOCATE, or LOCATE_IN_STRING functions can be used to operate with awareness of the database collation and the string units. LOCATE the index of your delimiter. LOCATE('-','CHG-FFH') NOTE: DB2 provides two functions which can be used for this: POSITION (or POSSTR), and LOCATE (or LOCATE_IN_STRING).
