First-rate SQL Coders, Specialists for Hire in Ukraine

SQL is the language of queries to relational databases. Allows you to manipulate information (extract, edit, delete, change structure, etc.), which is stored and systematized by specialized software – DBMS (database management system). Common examples of the latter are MariaDB, MySQL, PostgreSQL, ORACLE, MS SQL Server. SQL Server was created by Microsoft. The first version was released in 1987. And the current version is version 16, which was released in 2016 and will be used in the current manual. SQL Server has long been an exclusive database management system for Windows, but since version 16, this system is also available on Linux. To organize databases, MS SQL Server uses a relational model. This database model was developed back in 1970 by Edgar Codd. And today it is actually the standard for organizing databases.

Questions and Answers related to SQL Development

What would you do at the query and database levels to optimise an SQL query?

“On the select side: if db engine supports it run explain analyze on the query to find what is taking the most time.(if you have a hard time interpreting that then take your query apart and slowly add to it executing it at each step, seeing where it slows down). Then think of ways replace that step or work around it in a different way. On the db side: check to see if any columns should have indexes that don’t. Especially columns that are being joined on. Also checking datatypes can help give an idea of how to get it to perform better…”

How do I prevent SQL injections and ransomware attacks?

“SQL injection problem is well understood and documented for years in OWASP top 10. Primary defenses include use of Prepared SQL statements. Sometimes stored proc can force the use of parameters, validating all inputs and not, passing them directly to database server, escaping all User inputs and wildcards, Reducing scope /privilege of user account.”

What is the most dangerous command in SQL?

“TRUNCATE is pretty bad: deletes all the data in a table and typically auto-commits so it takes effect immediately rather than after a COMMIT. Some DBMS support DROP DATABASE which drops all tables in the schema and release all storage which also can’t be reversed.”
