Answer 1

insert into ##temp1 select * from TableName
select * from ##temp1

Explanation:

We need to put "##" with the name of Global temporary tables. Below is the syntax for creating a Global Temporary Table:

CREATE TABLE ##NewGlobalTempTable(
UserID int,
UserName varchar(50), 
UserAddress varchar(150))

The above script will create a temporary table in tempdb database. We can insert or delete records in the temporary table similar to a general table like:

insert into ##NewGlobalTempTable values ( 1, 'Abhijit','India');

Now select records from that table:

select * from ##NewGlobalTempTable

Global temporary tables are visible to all SQL Server connections. When you create one of these, all the users can see it.
