FAQ
Which databases do you support?
I specialize in Oracle SQL and PL/SQL. I can also review general SQL queries from other database systems after confirming compatibility.
What information do you need to begin?
Please provide the SQL query, database platform and version, problem description, and execution plan if available. Use anonymized or synthetic data.
Will you guarantee faster query execution?
No specific speedup can be guaranteed. I will identify likely bottlenecks and recommend improvements based on the available information.
Do you need access to my production database?
No. Most initial reviews can be performed using SQL queries, execution plans, and sanitized database information. Production access is not included.
Can you optimize stored procedures or ETL jobs?
Yes, I can assess Oracle PL/SQL procedures and ETL-related SQL performance. Please contact me first for complex requirements and custom pricing.
