My TRANSACTION Notes

XACT_STATE() 

https://docs.microsoft.com/en-us/sql/t-sql/functions/xact-state-transact-sql?view=sql-server-ver15

0 = no active transaction

1 = active transaction

-1 =  active transaction but your only option is ROLLBACK (it's doomed)


@@TRANCOUNT

BEGIN TRANSACTION increments by 1

COMMIT TRANSACTION decrements by 1

ROLLBACK TRANSACTION sets to zero (except when using SAVEPOINT)


SET XACT_ABORT { ON | OFF }

ON = error causes transaction to ROLLBACK

Using sp_executesql with OPENQUERY

 gemini prompt: give me the in depth details on using openquery in sql server with the sp_executesql stored procedure The OPENQUERY function in SQL Server allows you to execute a pass-through query on a specified linked server . By design, OPENQUERY 's arguments—the linked server name and the query string— do not accept local T-SQL variables . However, you can overcome this limitation, particularly for parameterizing the query string, by using dynamic SQL executed via the system stored procedure sp_executesql . Here is an in-depth breakdown of how to use OPENQUERY with sp_executesql to include variable values in your remote query. 1. The Challenge: Parameterizing OPENQUERY The fundamental restriction of OPENQUERY is its syntax: SQL OPENQUERY ( linked_server , 'query' ) Neither linked_server nor the 'query' string can be a local SQL Server variable (e.g., @MyLinkedServerName or @MyQuery ). To pass a variable (like a specific CustomerID or a date range) into...

Executing Remote Queries Safely and Efficiently with sp_executesql

 gemini prompt: provide a blog post by a database professional on the best practice for using sp_executesql to query a remote sql server database Executing Remote Queries Safely and Efficiently with sp_executesql As database professionals, we often face the need to query data from a remote SQL Server instance . While options like simple four-part names (e.g., [Server].[Database].[Schema].[Table] ) or OPENQUERY exist, using sp_executesql in conjunction with linked servers provides a powerful, secure, and flexible approach, especially when dealing with dynamic SQL. Here's a breakdown of the best practices for leveraging sp_executesql for remote queries. 1. Why sp_executesql for Remote Queries? When executed locally, sp_executesql is primarily used to execute dynamic SQL safely by allowing you to parameterize the query string, which is the fundamental defense against SQL injection . When querying a linked server, you can use it to execute code directly on the remote server...
