Hi,

Do we have any algorithm or procedure or a user defined function to which i can pass the tables names and it should tell me the loading sequence.

For example i have 3 tables say A,B,C where A and B are master tables and C is a transactional table which references A(c1) and b(id).

If i pass the tablenames to the stored procedure/functions, it is should suggest me the loading sequence.

declare @tableList varchar(100);
set @tableList = '''C'',''A'',''B''';
exec sp_showLoadingSequence(@tableList)

--Expected output
A,B,C

If anyone has tried this before????????


I can go for Database diagram but if we are having large set to tables to be loaded then it is becoming great confusion. so, i thought if we can find out a way from T-SQL then it will be good.

Any thoughts will be greatly appreciated!

Thanks in Advance

There is a script somewhere here that determines the parent-child order of foreign keys - in order to allow Deletion/Truncation of child-then-parent, would that help?
