Q: What if I'm not sure which package to choose?
Please send me a message before placing an order! Just describe your problem, what you need to achieve, and which database system you're using. I'll review your requirements and send you a custom offer that perfectly fits your needs. This ensures you only pay for what you need.
Q: What information do you need from me to start? A: To get started, I'll need three things:
-Your database type (Oracle, DB2, MySQL, or PostgreSQL). -Your table structure (table names, column names, and data types). A screenshot of your database diagram (ERD) is perfect if you have one. A clear description of what you want the query to do, including any "WHERE" conditions and the specific
Q: My query is running very slowly. Can you help?
Yes, absolutely. Query optimization is one of my key services. This type of work usually falls under the Standard or Premium package. Please send me your current query and any details you have on its performance (like an EXPLAIN plan), and I'll let you know how I can speed it up.
Q: Do you only write queries, or can you also design my database schema?
This gig is focused on writing, fixing, and optimizing SQL code (queries, stored procedures, functions, etc.). Services like database design from scratch, normalization, or server administration are not included. If you need help with database design, please message me for a custom offer.
Q: What if the query you deliver has a bug or doesn't work as expected?
Your satisfaction is my top priority. All my packages include revisions. If the query doesn't work as per the requirements we agreed upon, I will fix it quickly at no extra charge. I'll work with you to ensure the final code is 100% correct.
Q: Can you explain the query you write for me?
Yes! I write clean, readable SQL and will include comments in the code to explain what each major part of the query does. If you need a more detailed, line-by-line explanation, I'm happy to provide that.
Q: Do you also work with Microsoft SQL Server (T-SQL)?
My primary expertise for this gig is Oracle, DB2, MySQL, and PostgreSQL, as listed. While I do have experience with MS SQL Server, please message me before ordering so we can discuss your specific requirements, and I can confirm that I am the best fit for your task.
