Rolls back a user-specified transaction to the beginning of the transaction.
Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
This statement functions identically to ROLLBACK TRANSACTION except that ROLLBACK TRANSACTION accepts a user-defined transaction name. With or without specifying the optional WORK keyword, this ROLLBACK syntax is ISO-compatible.
When nesting transactions, ROLLBACK WORK always rolls back to the outermost BEGIN TRANSACTION statement and decrements the @@TRANCOUNT system function to 0.
