I will write, fix and optimize your database queries
About this Gig
Is a SQL query returning the wrong result, running slowly, or proving difficult to write?
Im Rodrick, a software developer with over 18+ years of experience working with business databases. I can write, debug, and improve SQL for MySQL, PostgreSQL, and Microsoft SQL Server.
Depending on your package, I can help with joins, filters, summaries, reporting queries, data corrections, stored procedures, functions, or triggers. You will receive readable SQL and an explanation of what it does. I will check the result against the sample data and expected output you provide.
Please send your database type and version, relevant table structures, a small sample of data, and the result you expect. If you already have a query, include it and describe the error or incorrect result.
The packages cover the stated number of queries and tables. A full database redesign, application changes, server troubleshooting, or work on a large production database needs a custom offer. Message me first if you are unsure which package fits.
