Transactions in SQL Server

Transactions in SQL Server
 
A test was performed to show how transactions work in SQL*XL in a connection to SQL Server.  
 
We use SQL*XL to call a stored procedure in the SQL Server database to add a row to the test database. We will inspect the creation of the new row in SQL*XL and also in the database server. Using the transaction button in SQL*XL we have control over the transaction.
 
We used SQL Server 2008 Express and SQL*XL 5.1.7.
 
The following command was run in the SQL Server database to create the procedure that inserts the row.
 
alter procedure test_proc1
as begin
 
set nocount on
begin transaction
 
inse [/code] [code]rt into dbo.test(id, a)
values (1,123)
 
commit transaction
 
end
go

 
From SQL*XL, in the SQL dialog the following command is run:
exec test_proc1
 
Next in SQL*XL the command: select * from test is executed. The inserted row is displayed in Excel.
Next in Microsoft SQL Server Management Studio the same select statement is executed. The query is hanging because probably the table is locked by SQL*XL.  
When pressing the commit button (or rollback button) in SQL*XL the transaction is ended (despite the commit transaction in the stored procedure) and the result can be seen in SQL Server. The creation of the row is canceled when the rollback button was pressed.
