TargetPrefix Attribute
Data Type: varchar(256)
4GL Access: RW
The TargetPrefix attribute specifies a prefix to be attached to all compiled expressions used in target mappings in which the QueryParm's UsePrefix attribute is set to TRUE. For example, if all fields are to be put into a composite field called compfield, you could set the QueryParm's UsePrefix for each of the targets and put compfield in the TargetPrefix attribute, avoiding the need to specify the composite field name for every expression.
Note: You must include the trailing period if it is required in the expression that concatenates this text value with the field name.
