Commit or Rollback

SQL Optimizer > Optimized SQL > Batch Run > Commit or Rollback

In order to obtain the correct result during the Batch Run or Run Time of alternative SQL statement, the SQL statement executes against the database. However, when executing UPDATE, INSERT, DELETE statements, any changes to the database are rolled back.

Note: For UPDATE, INSERT and DELETE SQL statements, while retrieving the run time and run result you may encounter the following Adaptive Server error message:

Can't allocate space for object 'syslogs' in database 'database_name' because the 'logsegment' segment is full. If you ran out of space in syslogs, dump the transaction log. Otherwise, use ALTER DATABASE or sp_extendsegment to increase the size of the segment

This is due to the lack of space in system table (syslogs), in which all changes to the database are recorded. Empty the transaction log in the database and re-execute. Use the following command in the SQL Workshop module:

DUMP TRANSACTION database_name WITH TRUNCATE_ONLY

go
