Hi,

when I using ObjectScript Trigger Code , I want to get whether the fields has changed by using "{fieldName*C}" ,  actually, fieldName in "{fieldName*C}" is a real field name ,but in my code, fieldName is a variable as follows:

		SET stat=##class(%SYSTEM.SQL).GetColumns(tableName,.byname,.bynum,1)
		IF stat=1{
			SET i=1
			WHILE $d(bynum(i)){
				SET xColName=bynum(i)
				SET valComp={xColName*C}
				
				IF valComp=1{
					SET oldVal=1 //{xColName*O}
					SET newVal=2 //{xColName*N}
					&sql(INSERT INTO Yan.
