Looking for SQL expert who has experience with the stored procedures to debug and fix the errors
I have a collection of fully structured datasets already living in a Databricks workspace and now need a clean, scalable schema that takes advantage of Databricks SQL in a cloud-based environment. The work involves analysing the existing tables, proposing an optimal relational model, and then producing the physical DDL so I can deploy everything straight into Databricks. Key goals • Normalise the data where it makes sense, but stay pragmatic for query performance. • Define primary and foreign keys, partitioning and clustering strategy suited to Spark execution. • Provide clear, version-controlled DDL (Databricks notebooks or .sql files) plus an ER diagram so future teammates can understand the design quickly. Acceptance criteria – All tables created success...

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 have been running my numbers in spreadsheets for far too long and now need a properly structured Microsoft Access solution. The goal is to design and optimise a database whose sole focus is managing financial data—specifically our invoices and billing records. Here is what I need from you: • A relational schema that keeps the tables normalised, eliminates duplicate data, and supports growth. • Intuitive forms for entering new invoices, applying payments, and updating client details without exposing raw tables. • Parameter-driven queries and summary reports that let me filter by client, date range, paid / outstanding status, and export cleanly to Excel or PDF. • Thoughtful use of indexes, validation rules, and VBA where necessary so the system stays fast ...
We are looking for an experienced data analyst / developer to help us build a visual dashboard for inventory and sales performance, based on data from Loyverse POS (Back Office + API). Our company operates multiple retail stores (costume jewelry), and we need a reliable system to monitor stock, sales trends, and optimize purchasing decisions. Current Situation (Manual Process): At the moment, we rely on manual exports from Loyverse: • Export of current stock data (with unique SKU per product) • Export of sales data over a selected period (e.g., 30 days) • Calculation of average sales per product: Average Daily Sales = Quantity Sold / Number of Days Limitation: This method does not account for out-of-stock periods, which leads to inaccurate sales averages and poor resto...
I need a production-floor MIS dashboard built in Power BI that lets our garment-manufacturing managers see every line’s output and efficiency at a glance. The single most important view is line-wise production and performance tracking, but the same report must also surface quality indicators so we can spot defect trends early. Here is the flow I picture: • A landing page that shows yesterday’s pieces produced per line, the corresponding efficiency %, and an overall quality score. • Time-based slicers (day, week, month) that instantly recalc every visual. • Drill-through or drill-down so a supervisor can jump from a plant summary into an individual sewing line, then right into an operator if the data exists. • Clean, executive-level visuals that someo...
I’m building a small-scale e-commerce demo and need someone who can put together an eye-catching, interactive storefront with just enough backend logic to prove the concept. Scope • Modern, responsive UI that showcases sample products with images, descriptions, price, and inventory status. • Lightweight checkout flow: cart, address and payment forms, but the payment step can stop at a confirmation screen—no real gateway hookup for now. • Basic database layer to store products and capture mock orders so I can review them in an admin view or via simple SQL queries. • Clean code structure that I can later extend into a full production build. Tech is flexible—React, Vue, or a templated PHP/Node stack all work for me as long as the final site loads ...

I’m building a data-driven application that delivers complete game-level and player-level analytics for four sports: Football, Cricket, Formula One, and Tennis. The goal is to merge historical and live feeds into a unified warehouse, run advanced modelling on top of it, and expose the results through interactive dashboards and an API other products can tap into. Scope of work • Set up or connect to reliable data sources, normalise them, and design an extensible schema that copes with multiple sports and rule sets. • Develop the ETL pipeline (Python, SQL, Spark or a comparable stack) to ingest, clean, and enrich the data in near-real-time. • Build an analytics layer capable of producing player performance metrics, match summaries, and cross-sport comparisons.

The registration form at crashes with an HTTP 500 the moment it is submitted, and the submission never reaches the MySQL table. phpMyAdmin also throws the same 500 page right after the failure. I have not touched the PHP or MySQL configuration, and there have been no recent updates or installs on the server. I do, however, have full access to the error logs—I’m just not sure how to interpret them—so you are free to dig into those. What I need is straightforward: locate the underlying cause of the 500, repair it, and confirm that every new form entry is successfully written to the database without breaking anything else on the site. Deliverables • Identify and fix the code / server issue causing the HTTP 500 • Verify data is inserting correctly into MySQ...

I have a SQL Server view that already aggregates every validation script we run on raw_valid and model_valid. What I now need is the front-end: an interactive Power BI dashboard built in a tabbed interface that surfaces those scripts, lets users explore them, and provides both basic text search and advanced filtering. Connection & data model • Connect directly to the existing view (read-only). • Expose the script name, object type, target table, last run date, status, and the full script body or a hyperlink to it. • Optimise the model so the dashboard opens quickly even when the view grows. Visual & navigation requirements • Two main tabs—one for raw_valid scripts, one for model_valid—each mirroring the same layout for consistency. ...

I’m putting together a comprehensive backtest that focuses exclusively on stock market data from the NYSE and NASDAQ, spanning the last 10 years. To do this effectively I need a well-structured historical dataset that I can drop straight into my models without hours of manual cleanup. Here’s what I’m after: • Daily (or finer) OHLCV prices, fully adjusted for corporate actions, splits, and dividends. • Consistent symbol mapping so delistings, mergers, and ticker changes don’t break the series. • A single, tidy delivery format—CSV files are fine, but a lightweight SQL or Parquet database also works if you prefer. • A short README that explains field definitions, adjustment methodology, and any known data caveats. If you already have a...
Both of my access-control platforms—System A (Suprema's Biostar X) and System B (dormakaba's Matrix Professional)—sit on the same Windows server and share a local MS SQL instance. Each exposes a REST API, yet today they operate in silos. I need a seamless, bi-directional integration so that any change to a person or employee record in one system is reflected in the other almost instantly. Scope of the sync • Core identity fields: name and unique ID • Credential data: RFID card number and state • Biometric assets: fingerprint templates • Media: profile picture • Security attributes: access-level permissions Key requirements 1. Real-time operation (sub-second latency acceptable). 2. Conflict-resolution logic—latest change...

My PHP application is already online and fully connected to MySQL; it just needs a couple of light touches. In total I expect two-to-three quick updates, the most notable being the addition of a small feature that slots straight into the existing codebase. The other tweaks are straightforward logic or display adjustments—nothing structural, no schema changes, and certainly no rebuild. The code is plain PHP with direct SQL (no frameworks). A solid grasp of PHP, MySQL, and rapid debugging will let you dive in, trace the current flow, and wrap things up fast. Once we’ve talked through the exact lines to touch, I’ll share the repository and a database dump so you can run it locally. Deliverables • Updated PHP files with the new feature and minor fixes implemented &...

I need a seasoned Power BI developer to turn a very large, highly-granular data set into a single, dynamic dashboard focused on monitoring key operational-efficiency KPIs. Here’s the landscape you will step into: our raw information sits in both SQL databases and a series of regularly exported Excel/CSV files. I want a model that connects to each source, transforms the data so that it’s truly analysis-ready, and then visualises the metrics that matter—cycle times, throughput, bottleneck alerts, utilisation rates and any supporting drill-downs we decide to add. Scope of work • Build or optimise the data model, including merge logic between SQL and CSV tables, DAX measures, and relationships that guarantee a fast, responsive user experience even when the data vol...

My in-house ERP, built with PHP 8, Alpine JS, and htmx, has a data-processing fault: new or edited records are failing to persist to the database. The problem shows up only in two modules—Inventory Management and Financial Transactions—while all other areas work as expected. The core workflow: a user edits a record, htmx issues an async POST, the PHP controller validates and writes through an ORM to MySQL. The front-end confirms success, yet the row never appears (or reverts on refresh). No errors are thrown in the browser console, but MySQL slow-query logs stay clean, so I suspect a logic or transaction issue in the controller or model layer. I will grant repository access (Git) and a staging URL. The schema and seed data are documented in README. Deliverables • Di...

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...
