Depends on whether you want not to have all 3 or either one.If either one you can change it to ORSelect * from fueltrans with (nolock) Where (location not like '%capalaba%') AND (location not like '%ormiston%') AND (location not like '%thorneside%') |

| Using NOT LIKE will force a scan through all possibilities.There are probably more efficient ways. You're using NOLOCK in your initial query. If you're also issuing updates , inserts this could cause dirty reads. Is that intended behaviour?Jack Vamvas--------------------http://www.sqlserver-dba.com |

| keep in mind if you're to implement READ_COMMITTED_SNAPSHOT isolation level there is added pressure on the tempdb. Tempdb can potentially be a serious bottleneck.Of course , it is possible to tune the tempdb , such as the type of storage , file numbers etchttp://www.sqlserver-dba.com/2011/04/tempdb-performance-and-strategy-checklist.htmlJack Vamvas--------------------http://www.sqlserver-dba.com |
