Database Programmers store and handle databases, create, maintain and update them so that data is organized, secure, and easily retrievable when needed. Database programming relies on the manipulation of an underlying language, like SQL, through coding structure and automation of rules to ensure accuracy and enforce consistency.

Conform celor 153,098 recenzii, clienții îi evaluează pe Database Programmers cu 4.82 din 5 stele.I need a reusable SQL/PL-pgSQL routine that can handle Create, Read and Update actions against any table in my PostgreSQL database. Table names, column sets and primary keys will be supplied at runtime, so the logic must build its statements dynamically while remaining fully safe against SQL-injection. The procedure has to accept and correctly persist or retrieve every column type I might throw at it—numeric, text, date/time, JSON, arrays and any other standard Postgres datatype—without me having to hand-code separate cases. Deliverables • One well-commented function or set of functions packaged in a .sql file • A short README showing call examples for each action (insert, select with filters, update) and explaining required parameters • Proof it work...
I need an experienced SQL Server DBA specializing in DACPAC operations for database deployment. The project involves deploying a DACPAC package to SQL Server 2019, including schema changes. Key Requirements: - Expertise in SQL Server 2019 - Proficient in DACPAC deployment and management - Experience with schema changes and database upgrades - Strong problem-solving skills and attention to detail Ideal Skills: - SQL Server Database Administration - DACPAC and BACPAC knowledge - T-SQL proficiency - Experience with SQL Server Management Studio (SSMS) Looking for a reliable professional to ensure smooth and efficient database deployment.
I need a single, fully-parametric SQL solution that can handle Select, Update and Delete operations—as well as Insert—against any table in my PostgreSQL database. The goal is to pass in a table name, a dynamic list of column names, variable data types and the necessary filter or value clauses, then have the function build and execute the correct statement on the fly. Here is what I expect: • A PL/pgSQL function (or clear alternative, such as a prepared statement generator) that accepts: – target table – columns and their values or filters – operation flag (select / insert / update / delete) – optional returning clause for selects • Robust handling of variable data types so the same call works for integers, text, timestamps, JSO...

I need help transferring text-based records that currently live in my MySQL database into a clean, well-structured format I can work with outside the system. The job is purely text data entry; no calculations or analytics are required. You will connect to the MySQL tables I specify, pull the relevant fields, and re-enter that information exactly as it appears, maintaining case, accents, and punctuation. Because the source is a live database, accuracy and consistency are critical. I will supply read-only access credentials along with a field-mapping guide so you know which columns belong in which destination fields. Deliverables • A final file (CSV or Excel—your choice) containing every required record, fully cross-checked against the source tables. • A quick summary o...

I have a set of digital files that contain purely numerical information, and I need every figure transferred accurately into my existing database. You will be working directly with the database layer—so familiarity with typical SQL interfaces or import tools is essential. The files are already in clean digital form; your task is to extract each number, verify it matches the source, and insert it into the correct tables and fields. Once the upload is complete, a quick cross-check against the originals will confirm that no values were missed or altered. Deliverable • A fully populated database reflecting 100 % of the numbers in the supplied files, with spot-check verification passed. If you’re comfortable manipulating numeric datasets and working inside a live dat...
I need an experienced Notion builder to create a streamlined personal-organization hub focused on two things: keeping my tasks under control and tracking the goals that matter most to me. The core database should open in List view—this is how I naturally process information—yet still be structured well enough that I can later switch to Kanban or Calendar if I ever change my mind. Here’s what the workspace must cover: • A task-tracking system with statuses, priorities, due dates, and a clean List view as the default. • A goal-setting area that links seamlessly to the tasks so every action clearly rolls up to a bigger objective. Once the build is complete, I’ll also need a quick loom or written walkthrough so I can tweak properties and filters on my ...

I’m running a DHIS2 instance for a health programme and need reliable support for ongoing data entry and management. The work is entirely within DHIS2—importing routine service data, checking for completeness, running the built-in validation rules, and resolving any inconsistencies before the monthly reporting deadline.

Day to day, I’m looking for both technical troubleshooting and functional guidance so users can keep working without interruption.

Once those pains are addressed, I’d like you to stay available for routine health checks, root-cause analysis when anomalies appear, and advice on best-practice configurations or minor functional tweaks.
