Oracle, Microsoft SQL Server, PostgreSQL and MySQL.
Can you troubleshoot a slow SQL query?
Yes. I can review the query, execution approach and relevant database information and recommend optimization.
Can you work with production systems?
I can provide troubleshooting and recommendations, but production changes should be performed under the client's approved change and access procedures.
