FAQ
What information do you need before starting?
Please provide the SQL query, table structures, relevant indexes, expected output, database version, and details about the performance issue. An execution plan and sample data are helpful where available.
Which databases do you support?
This Gig primarily supports MySQL and MariaDB. Please contact me before ordering if your project uses another database platform.
Can you optimize complex joins and subqueries?
Yes. I can analyze and optimize joins, nested subqueries, aggregations, filtering conditions, and other complex SQL logic, depending on the selected package.
Will you recommend database indexes?
Yes. Where appropriate, I will recommend indexes based on the query structure, filtering conditions, joins, and available execution-plan information.
Can you guarantee a specific execution speed?
No exact execution time can be guaranteed because performance also depends on data volume, server resources, configuration, indexes, and application workload. However, I will provide practical optimization improvements and clear recommendations.
Do you need access to my production database?
Usually, no. In most cases, the query, table structures, indexes, execution plan, and sample data are sufficient. Do not share production passwords or confidential customer information.
