| You should look into RCSI isolation level. You could use the nolock hint, however the insert/select could get bad data due to the dirty reads.Tara KizerSQL Server MVP since 2007http://weblogs.sqlteam.com/tarad/ |

| There is no process that could read or write into Table A during the transaction . Also there could be no process that could write data into Table B during the transaction. I could only have reads for table B while transaction runs.. Also I cannot go and change the read process because and apply nowait there.. So is there a way i could run this transaction in a way that the read on table B remains unlocked |
