Hi
I encountered a problem when I'm trying to import data from a flat table to
several tables of the same databases.
There are about 1 mln records inside the flat table called XX_ZRODLO. The
stored procedure for import seems to work and import data but after about
15000 it stops and it seems as though QA is hung up.
After restart of SQL and shutdown QA - the procedure for import can import
another about 30000 records and then the same agian QA is dead ...
Where could be the problem?
This is the procedure to import data (1 mln records) from table XX_ZRODLO to
several tables of databases according to its structure.
CREATE procedure XX_IMPORT
as

It seems that the id column is a natural key for this and therefore you
could do this using set based operations and not a cursor. This would speed
up your process.

Launch another QA session and look at the sysprocesses table - is there
blocking? Does the spid that your import is using show a waittype? Are
you see a delay due to autogrow?
