somecolumn in (SELECT lookupcolumn from dbo. smallertable) Select Bigtable.id, somecolumn from BigTable INNER JOIN (SELECT DISTINCT lookupcolumn FROM dbo. Smallertable) as s = dbo. Bigtable.somecolumn Finally the query cost and the above is not the same, at this time the query performance cost is the same, I believe here we should be very clear. We can derive the performance overhead of inner join and in by the above-mentioned large number of pages, and when we are initially exploring the pe

50 tips for optimizing query: (see which one is suitable for you) 1. Place data, logs, and indexes on different I/O devices to increase the reading speed. In the past, tempdb can be placed on raid0, which is not supported by SQL2000. The larger the data size (size), the more important it is to increase I/O. 2. vertically and horizontally split the table to reduce the table size (sp_spaceuse) 3. upgrade hardware 4. Create an index based on the query co
