Slow Insert to LinkedServer
Posted on 2006-10-23
Insert statement to remote server is running very slowly. I have run Profiler and find there is a 'sp_cursor' call for each row. The source system is SQL2005 and destination is SQL2000(sp4). The linked server is using 'SQL server' type connection. Source query is against a single table with a where clause. source and destination table are identical with Primary keys. Purpose is just to move the rows. Connection is a slow network connection - should be ok. I have already overcome same problem for related update and delete queries by use of 'EXECUTE (query) AT LinkedServer' that works great - but insert can not take advantage of this...
WHERE col1 = '7/20/2006'
AND col2 in (2,5,7,12,32,54,45,33)
