StringValue Method
The StringValue method re-evaluates the expression that was specified when the DynExpr was created and converts the result to a string.
This method has the following syntax:
varchar(256) = DynExpr.StringValue()
The DynExpr must not represent an object (for example, a reference variable). If it does, the StringValue method's behavior is undefined. If the value of the expression is null, the StringValue method returns NULL.
