Question of the Day

Today's question (by Steve Jones - SSC Editor):
	The Isolation Level Across Databases
I have a table in a couple databases with a fullname of "Steve Jones" and a firstname of "Steve". With one connection, I run this in the database, sandbox2: BEGIN TRAN UPDATE dbo.A SET firstname = 'Delaney' WHERE fullname = 'Steve Jones' This transaction is open. I now run this on a second connection in the sandbox database: set transaction isolation level read uncommitted; use sandbox SELECT * FROM dbo.A AS a1 INNER JOIN sandbox2.dbo.A AS a2 ON a2.fullname = a1.fullname For the row with fullname="Steve Jones" that is queried in sandbox2, what is returned for the firstname?

Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Once a Month

I have a procedure that I want to run once a month, on the first Tuesday of the month. What is the easiest way to get this done?

Answer: There is an option in the SQL Agent scheduler to run something on the first Tuesday of the month.

Explanation: The SQL Agent includes options to run something on the first occurrence of a day of the week. You can pick the first Tuesday of the month for a job to run. This is in the GUI or in sp_add_schedule. Ref: sp_add_schedule - https://learn.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-add-schedule-transact-sql?view=sql-server-ver16
