Intent exclusive locks.

    Hi All,

    I had a situation today wherein the SQL developers where able to run select query on a particular table, but they were not able to run an Update query on it,

    I checked the sysprocesses and found that the table they are updating is locked by another proc which has held IX(or SIX) lock on the table.

    I just wanted to know how they were able to query the table without a (nolock) hint when the table had an IX(or SIX) lock on it..

    Thanks
