FAQ
What information do you need to start?
I need the SQL query or stored procedure, relevant table structures, SQL Server version, expected result and a description of the current error or performance issue.
Do you need access to my database?
Usually no. I can work with SQL scripts, sanitized sample data and execution plans. If database access is necessary, it must be discussed before placing the order.
Can you guarantee a specific performance improvement?
Performance depends on data volume, indexes, hardware, server configuration and application usage. I will explain the improvements found, but I cannot guarantee an exact percentage before reviewing the query.
Do you work with Azure SQL Database?
Yes. I can analyze and optimize queries and stored procedures for SQL Server and Azure SQL Database.
Will you modify my production database?
I normally provide reviewed SQL scripts for testing. Production changes should only be executed after validation and with a current backup.
