Find the Primary Keys of NAV Tables

Chinmoy

Hi,

I was trying to find out the keys of some tables of NAV (native Db). I did it with the following code in a report / form and populated a table with the keys:

RecRef RecordRef
i Integer
Keys Text 250
ObjectList Record Object List
ValidateTable Record Field

FOR i := 1000000 to 10009999 DO
//Just a specified range of tables
BEGIN
ValidateTable.RESET;
ValidateTable.SETRANGE(TableNo,i);
IF ValidateTable.FINDFIRST THEN
BEGIN
RecRef.OPEN(i);
Keys := '';
Keys := RecRef.CURRENTKEY();
IF Keys <> '' THEN
BEGIN
ObjectList.INIT;
ObjectList."Object No." := i;
ObjectList."Object Caption" := Keys;
ObjectList.INSERT;
END;
RecRef.CLOSE;
END;
END;

Note: I cannot take a backup of the db and restore on SQL server. I only have access to the NAV db with limited administrative permissions

Is there any other better way to do this?

Kind regards,

Take a look at Table 2000000063 Key.

Good one. I guess the clustered indexes are the ones which are the primary keys.

Thanks!

Not necessarily. Keys and Indexes are handled differently. But indeed, in most cases the PK is also flagged as "Clustered".

Exactly. Just filter on "Key ID" = 1 :thumbsup:

Thanks again! This is working as expected.
