After careful study, it is still a bit complicated to find the explicit transaction (display transaction) inside SQL Server. Here are some summaries:Commit TRANSACTION commits all nested transaction modifications. However, if the nested transaction contains rollback TRAN to save point, then the portion after save point will be revert out.Delete fromdbo.numbertab

SQL Server's TRUNCATE transaction rollback operation method, servertruncate We generally think that TRUNCATE is an operation that cannot be rolled back. It will delete all data in the table and reset the Identity column. If you perform the TRUNCATE operation in the transaction, you can roll back. Otherwise, it will not recover data from the log file. It does not record the deleted data in the log file. It o

/* When multiple stored procedures are called in a large SQL statement and multiple stored procedures are called in the called stored procedure, after multiple nested calls, if you need to roll back the entire transaction if the primary key is repeated or the business logic is not met, you can use the following mode for processing. You can also directly count data without raiserror. If an error occurs after the set xact_abort on operation, the transac
