Description

The DBRELATION() function is synonymous with the RELATION() function. The DBRELATION() function returns the linking expression of a specified relation in the current workarea. The <expN> specifies the position of the desired linking expression from the list of previously defined relations. The DBRELATION() function always returns a character string in lower case. If there is no linking expression defined for the <expN> selected a null string will be returned.
