Hi Tom,

How can we get data from a table at the time query initiated ? assume, my table is very big and the query i'm using to get the data taking long time, mean while, there might be some records got updated, but, I wanted to see the result as is at the time of query initiated.

Thanks in advance!

That is *always* the case for Oracle. There is nothing you need to do.

When you start a query, the results are immediately "pre-ordained" - they'll be as they were as the query started, no matter what changes occur whilst its running

Here's a couple of video that walk through the internals and the reason its good to know about it
