About this Gig
Is your SQL Server query failing, returning incorrect results or running too slowly?
I will investigate one T-SQL query or stored procedure (up to 250 lines), identify the cause and deliver a practical fix.
This package includes:
- Syntax and execution error troubleshooting
- Corrections to joins, filters, grouping and calculations
- Query analysis and optimization
- Execution-plan review and index recommendations where relevant
- Corrected SQL, a clear explanation and validation notes
Delivery: 3 days. Includes 2 revisions for the original agreed issue.
Performance comparisons are provided when a reproducible test is available. No fixed speed improvement is promised: results depend on your data, schema, indexes and server configuration.
Please message me first for production issues, multiple procedures or work requiring server access. Provide anonymized scripts, schema, sample data and errors; remove credentials and confidential information.
Full database rebuilds, ongoing administration, disaster recovery and new features are outside this package. Test changes before production deployment.

FAQ
Which databases do you support?
This gig focuses on Microsoft SQL Server and T-SQL. Message me first for Azure SQL or another database engine.
Do you need access to my server?
Many issues can be reproduced from anonymized scripts, schema and sample data. If access is necessary, we will agree on a restricted method first. Do not send credentials in the requirements.
Can you guarantee a specific speed improvement?
No fixed speedup is promised. I investigate the bottleneck and document measurable changes when comparable testing is possible.
What is included in a revision?
Adjustments to solve the original agreed issue within the package. Additional queries, new functionality or a changed scope require separate work.
