Question

cfquery, nolock, and cftransaction

A co-worker informed me the other day that using NOLOCK in a cfquery is pointless if you do not include the query inside a cftransaction. He claims that SQL Server will only recognize NOLOCK inside a transaction and thus not having the query within a cftransaction makes the NOLOCK redundant.


Can someone confirm is this is true or not, because in all the CF shops in which Ive worked , NOLOCK is used generously, and it is rarely ever inside a cftransaction. Am I supposed to think that all those queries in all those shops are not actually respecting the NOLOCK?

    cfquery sends an sql string to the db.  If that string includes No Lock, the db will react accordingly.
