| Yes it will rollback. Updating a huge number of records should be done in smaller batches to avoid contention and blocking.Harsh AthalyeIndia."The IMPOSSIBLE is often UNTRIED" |

Thanks, I am trying to update a table which has lot of indexes, so update is taking longer time.Any suggestion on how update can be performed on highly indexed table other than doing in batches. |

| Why don't you want to use batches? This is the recommendation for large data modifications.Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/ |
