| Hi! I'm experiencing the following experience problem with my SQL Server 2000. Explanation a' la example; 1. I insert data using my SP; EXEC dbo.up_DataInsert This is fine, SQL Profiler duration only a few ms. 2. I try to select the data. select * from dbo.tblData where DataNumber = 283279 This is fine, SQL Profiler duration only a few ms. 3. delete from dbo.tblData where DataNumber = 283279 This is NOT fine, SQL Profiler duration up to 50 seconds!!! I have got a unique index with ignore duplicate key and the table has about 180.000 records. What could be wrong here?? /Magnus |
