Randy Dyess

I have been working with SQL Server for over 5 years as both a development and production DBA. Before SQL Server I spent time as both a Visual Basic developer and Microsoft Access developer. Numerous projects upsizing Access to SQL Server lead me to become a full-time SQL Server DBA. Currently I have the privilege of working on one of the world's largest SQL Server "read-world" production installations at Verizon Communications for Verizon's billing project. We have 11 main databases totaling over 9 Terabytes of data with the largest single database over 2.2 Terabytes. My current position is as a development DBA, developing
new Transact-SQL code and enhancing existing code. Before working at Verizon, I worked at one of the largest advertising firms in America: Rapp Collins. There I supported up to 60 SQL Server web databases at a time, with some Oracle thrown in, doubling as both a development DBA and production DBA. Clients before Rapp Collins include: Auto One (a leading auto loan lender), Realpage, Inc. (leader in multi-housing management software) and BlueCross BlueShield of Texas (a large insurance company).

Question of the Day

The Read Committed Snapshot Isolation behaviour

I am currently working with Sql Server 2022 and AdventureWorks database. First of all, let's set the "Read Committed Snapshot" to ON: 

use master;
go

alter database AdventureWorks set read_committed_snapshot on with no_wait;
go
Then, from Session 1, I execute the following code: 
--Session 1
use AdventureWorks;
go

create table ##t1 (id int, f1 varchar(10));
go

insert into ##t1 values (1, 'A');
From another session, called Session 2, I open a transaction and execute the following update: 
--Session 2
use AdventureWorks;
go

begin tran;
update ##t1 
set f1 = 'B'
where id = 1;
Now, going back to Session 1, what happens if I execute this statement? 
--Session 1
select f1
from ##t1
where id = 1;
