Query Profiling Statements

Many database management systems offer built-in SQL statements for profiling queries. For example, in MySQL, you can use the EXPLAIN statement to see how the database optimizer plans to execute a query. In PostgreSQL, you can use EXPLAIN ANALYZE for even more detailed information

-- Explain a slow query to see its execution plan
EXPLAIN SELECT * FROM your_table WHERE condition;

-- Analyze a slow query in more detail
EXPLAIN ANALYZE SELECT * FROM your_table WHERE condition;
