ROLLBACK TRANSACTION

Learn ROLLBACK TRANSACTION in T-SQL through a focused explanation, a dedicated construct-specific example, an engineering boundary, and a mastery check.

10 min read • Intermediate

ROLLBACK TRANSACTION is an atomic T-SQL topic inside Transactions & Errors. This lesson focuses on how the ROLLBACK TRANSACTION construct is written, what it changes, and when it is the right tool.

Trace the example line by line. Identify the exact syntax for ROLLBACK TRANSACTION, the input state before it runs, and the resulting value, control flow, database state, hardware behavior, or runtime effect afterward. Neighboring lessons use different constructs rather than renamed copies of this one.

Topic-specific example

tsql-04-03-rollback-transaction.sql
tsql Try It Live 
BEGIN TRANSACTION; DELETE FROM Orders WHERE id=5; ROLLBACK TRANSACTION;
Edge case / engineering note

For ROLLBACK TRANSACTION, test the boundary that belongs to this exact feature rather than a generic failure case. Check invalid or empty input, NULL/unknown state, numeric limits, transaction or exception behavior, synthesis/runtime constraints, ownership/permission rules, or backtracking/control-flow effects where they apply.
