PostgreSQL has a separate command-line tool that’s been available for decades and is included with any installation of PostgreSQL. Many long-term PostgreSQL users, developers, and administrators rely on psql to help them quickly connect to databases, examine the schema, and execute SQL queries.

An important aspect of building and managing a database is organizing the objects within your database. You may have tables that support different functions, for example, a schema for warehousing operations and another for sales. Some logins may need access to some tables, but not others. You might want to isolate one set of objects within a database from other sets of objects. All of this, and more, can be accomplished using schemas within a database and PostgreSQL supports the use of schema for just these types of functions.

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; goThen, 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;See possible answers
