How to Handle Deadlocks in SQL Server?

  Deadlocks occur when two or more sessions permanently block each other. To handle and prevent deadlocks: Identify Deadlocks : Use the SQL Server error log or Extended Events to capture deadlock information. Enable trace flags 1204 and 1222 for detailed deadlock information. Deadlock Prevention : Ensure consistent access order for resources in your transactions. Keep transactions short and minimize lock duration. Use lower isolation levels if appropriate (e.g., READ COMMITTED instead of SERIALIZABLE ). Retry Logic : Implement retry logic in your application to handle deadlock exceptions gracefully. Use TRY...CATCH in T-SQL to handle deadlock errors.

How to Optimize a Slow-Running Query in SQL Server?

  Optimizing a slow-running query involves several steps: Identify the Bottleneck : Use SQL Server Profiler or Extended Events to identify slow queries. Use Execution Plans to understand how SQL Server processes your query. Index Optimization : Ensure proper indexing on columns used in WHERE , JOIN , and ORDER BY clauses. Avoid over-indexing, which can slow down INSERT and UPDATE operations. Query Rewriting : Simplify complex queries and break them into smaller parts if necessary. Avoid SELECT * and only fetch necessary columns. Use EXISTS instead of IN for subqueries. Statistics Update : Regularly update statistics using UPDATE STATISTICS to ensure the query optimizer has accurate data. Temp Tables and Table Variables : Use temporary tables or table variables wisely. Temp tables can be indexed, which may improve performance in some cases. Use of Proper Joins : Prefer INNER JOIN over LEFT JOIN if you only need matching records.
