ISTEMPORARY Function (RecordRef)
Determines whether a RecordRef refers to a temporary table.
Temp := RecordRef.ISTEMPORARY
RecordRef
Type: RecordRef
The RecordRef of a record that refers to a table.
Type: Boolean
true if the RecordRef refers to a temporary table; otherwise, false.
In versions of Dynamics NAV earlier than Microsoft Dynamics NAV 2013, if a RecordID or a RecordRef referred to a temporary table, then the table number value of the RecordID or RecordRef was the run-time generated sequence ID, which is from the base value of 2000100000. You could use the table number to determine if a RecordID or a RecordRef referred to a temporary table. In Microsoft Dynamics NAV 2018, the table number value of a RecordID or a RecordRef always contains the ID of the originating physical table and not the run-time generated sequence ID. If you previously used the TABLENO Function (RecordID) or the NUMBER Function (RecordRef) to test for the sequence number and determine if the RecordID or RecordRef was temporary, then you must use the ISTEMPORARY function in Dynamics NAV instead.
This example shows that you can replace code that you used previously to determine if a RecordRef referred to a temporary table. This example requires that you create a RecordRef variable named RecordRefVar.
// Previous code
IF RecordRefVar.Number >= 2000100000 THEN BEGIN
// Code for temporary tables
END;
// New code
IF RecordRefVar.IsTemporary THEN BEGIN
// Code for temporary tables
END;
