Serializable transaction isolation with multiple statements

原文 2013-10-07 21:33:58 0 1 sql/ tsql

I don't have a database supporting serializable transaction isolation to play with, but I wanted to understand something about it. If I insert a new row into a empty table and then do a select count from the same table within the same transaction; will the result be 0 or 1?

Update: According to this page https://my.vertica.com/docs/4.1/HTML/Master/2887.htm

It also sees the results of updates run within its transaction, even if they have not been committed.

True or false?

Yes it will.

Within a serialized transaction your view of the database is consistent with all changes you have made within the transaction.
