I will write, fix and optimize sql queries in oracle pl sql and mysql

Need a SQL query that returns the right rows, runs fast and is easy to maintain? I write, fix and tune SQL and PL/SQL for Oracle, PostgreSQL and MySQL.

I have worked as an Oracle Apps (EBS) technical consultant, building reports, PL/SQL packages and data fixes on live ERP projects. Every query I deliver is tested against sample data before you receive it.

What I can do for you:

• Write new queries for reports, dashboards and data exports
• Fix queries that return wrong results, duplicates or errors
• Speed up slow queries with better joins, indexes and execution plans
• Window functions, CTEs, pivots, running totals and ranking
• PL/SQL procedures, functions, packages, triggers and cursors
• Oracle EBS SQL for AP, AR, GL, PO, INV and OM tables

What you receive:

• Clean, commented SQL that you can run straight away
• A short note explaining the logic and any assumptions
• Test results on sample data

Please message me before ordering with your table structure, a few sample rows and the result you expect, so I can confirm the scope and delivery time.
