What is the term for a sequence of one or more SQL statements executed as a single unit?

The term for a sequence of one or more SQL statements that are executed as a single unit is known as a transaction. A transaction ensures that all operations within it either complete successfully as a group or, in the event of an error, none of the operations are applied at all, maintaining the integrity of the database. This concept is crucial in database management as it enables consistency and reliability, particularly in scenarios where multiple interdependent operations need to be executed.

For instance, if a transaction involves updating several related tables, and one of those operations fails, the entire transaction can be rolled back. This rollback feature ensures that the database does not end up in an inconsistent state due to partial updates.

In contrast, a batch job typically refers to a set of jobs or programs executed without user interaction, often scheduled to run at specific times. A procedure refers to a stored program that can encapsulate operations and return values, but it does not inherently guarantee the all-or-nothing property of transactions. A query, on the other hand, is specifically a request for data retrieval from a database and does not encompass multiple statements as one unit. Thus, the concept of a transaction embodies the idea of executing a sequence of SQL statements as a cohesive unit, reinforcing the integrity and
