Note:

Numeric Value	Constant Value	Description
2	%Query_ExprField	Field
3	%Query_Expression	Expression

This property is read/write.

Example

The following is used to test the expression to determine the property to use to retrieve it:

&MyExpr1 = &MyCrtColl.Next(); 
If &MyExpr1.Expr1Type = %Query_ExprField Then /* Expression is a Field */ 
   &OldExpr1Value = &MyExpr1.Expr1Field; 
   /* do processing */ 
Else  /* Expression 1 is an expression */ 
   &OldExpr1Value = &MyExpr1.Expr1Expression; 
   /* Do processing */ 
End-if;

The following is an example showing how to add a field for Expression 1.

/* add a new criteria */ 
&MyCriteria = &MyQuery.AddCriteria(); 
/* set the type of the first expression to be a field */ 
&MyCriteria.Expr1Type = %Query_ExprField; 
/* add the field EMPLID from the ABSENCE_HIST record */ 
&MyField = &MyCriteria.AddExpr1Field("A", "EMPLID");
