03.04 / HELP.EXEFREQUENT QUESTIONS
FREQUENT QUESTIONS
How does query optimisation start?+
By reviewing the SQL, execution plans, distribution and index access patterns.
Can TempDB or transaction log issues be addressed?+
Yes, but the underlying workload and maintenance strategy must be understood before simply shrinking files.
