Looking for SQL expert who has experience with the stored procedures to debug and fix the errors

I have a collection of documents that contain plain text which now needs to live inside my online database. Your task is simple: open each document I provide, copy the required text exactly as-is, and paste it into the appropriate fields of the database through the interface I will share. Accuracy is crucial—spelling, line breaks, and any basic formatting already in the source must remain intact. Once everything is migrated I will spot-check several records, so please be ready to correct any discrepancies quickly. Deliverables • Every document’s text entered in full, one record per document. • A brief completion log noting the total number of records created and any issues you encountered. If you have previous data-entry experience and are comfortable working i...

Thousands of lines of T-SQL that once worked are now returning incorrect results. I need a fresh set of expert eyes to comb through the entire script, pinpoint exactly where the logic breaks down, and fix it. The code lives in SQL Server. While you work through the main script, I also need you to cascade several hundred new parameters into a series of dependent stored procedures. These procedures already compile; they simply require the additional parameters to be wired through correctly so downstream calculations stay consistent. What I expect from you: • A clean, corrected version of the original query and any touched procedures • A concise change log explaining the root cause of the logical error and how you resolved it • Updated stored procedures with the new param...

I need help to finish an Access database I've started for my dog boarding business. I will provide the database file and detailed written instructions. Key tasks include: - Data input forms - Reports generation - Query optimization Ideal skills and experience: - Proficiency in MS Access - Experience with database design and modification - Strong attention to detail - Ability to follow detailed written instructions

I need a centralized storage solution for structured data with defined access controls. The data should be accessible via direct database access. Requirements: - Design and implement a centralized database solution - Ensure secure, defined access to the data - Provide direct database access for querying Ideal Skills and Experience: - Expertise in database design and management - Experience with data access security - Proficiency in SQL and database querying

I want to retire my desktop-bound MS Access file and move the entire solution to a browser-based JavaScript application backed by a MySQL database. You will receive the original .accdb file together with its relationship diagram, queries, forms and reports; your task is to reproduce every current feature so the new system behaves exactly the same—only now it runs online, is multi-user and can scale. Interface & UX The front end must feel modern and dynamic, with responsive layouts that work on desktop and tablet. I am open to any mainstream stack—React, Vue, Svelte or similar—as long as it stays JavaScript throughout and keeps load times low. Back-end & Data All existing tables and relationships should be migrated to MySQL. Any Access macros or VBA logic nee...

I need an Android application that brings every daily duty of a security guard into one place. The app must be modular so we can switch features on or off as sites require them, but the patrol-tracking module is non-negotiable. Patrol Tracking – mandatory • Real-time GPS tracking • Scheduled patrol routes • Checkpoint scanning (QR / NFC or similar) Beyond patrols I also want incident reporting, visitor handling, and any other practical “guard tools” you already have experience with; the goal is to reduce paper logs completely. Each module should share the same login and database so guards never juggle multiple apps. Please build natively for Android, use reliable location libraries (Google Maps, Fused Location Provider, etc.) and follow current Play ...

I want to replace paper timesheets with an automatic clock-in / clock-out system that identifies staff by face the moment they pass our main entrance camera. As soon as a recognised face crosses the frame, the system should log the arrival or departure time against that employee’s profile and store the record in an attendance database I can export to CSV or Excel. Architecture is open: I’m comfortable with a cloud, on-prem, or hybrid deployment—whichever you feel offers the best balance of accuracy, speed and privacy given a single entrance camera. No links to my HR or payroll software are needed for now, so a self-contained dashboard or lightweight web portal that lets me view, edit and download daily, weekly and monthly reports is perfect. Key deliverables &bull...

I’m looking for a reliable computer operator who can keep our day-to-day information flowing smoothly. Your core focus will be entering new database records with speed and accuracy, watching over system dashboards to catch issues before they turn into problems, and turning raw activity logs into clear, well-structured reports for management. You’ll work directly inside our database interface for record entry, using Notepad whenever you need a quick scratch-pad or to clean up text before pasting it into the system. While the data itself is structured, attention to detail is critical because any typo can ripple through multiple departments. On the monitoring side, I’ll count on you to keep an eye on resource usage, job queues, and error alerts, then note anything unusual s...
