Tips to hire a SQL developer
SQL is known as an initial language that is responsible for organizing and managing data in a relational database management system (RDBMS). RDBMS is the basis and primary for SQL, and also, for the rest of modern database systems such as MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access. Hire a SQL developer would bring the possibility to get more knowledge about relational databases and also, work on your relevant projects.
Hire a SQL developer, as the most demanding database
According to DV-Engines report about the ranking of the database trend, the top five popular databases would be regarding Oracle, MySQL, Microsoft SQL Server, PostgreSQL, and MongoDB in order. Although SQL would be in second place in the survey, we shouldn’t forget the undeniable increase of rising in usage and popularity of the SQL, during the previous years.

The key difference between SQL and NoSQL?
The most of what you will see in SQL are the tables-based databases whereas NoSQL databases have more option to recommend to the users such as document-based databases, key-value pairs, graph databases.
Hire a NoSQL developer with Perfectlancer, if you want to have document-based databases on your projects.
The key difference between SQL and PostgreSQL?
Hire a SQL developer can help for the e-commerce projects to provide different data warehousing solutions for their clients. There would be a mistake to compare the SQL with PostgreSQL.

The key difference between SQL and SQL server?
SQL Server is a database server that is provided by Microsoft. As an RDBMS tool, SQL and SQL server will execute the SQL statements. By hiring a database server, who would be known as a computer program, you will have the chance for database services to other programs or computers, as defined by the client-server model.
After all, if you want to be sure that your SQL developer that you are hiring, would be the most professional one, you need to just ask some questions about their SQL commands
The most important SQL commands
SELECT * FROM table; e.g. SELECT freelancers FROM table 1
SELECT age, name FROM freelancers WHERE age > 18;
SELECT name, age FROM freelancers ORDER BY name ASC (ascending), age DESC (descending)
SELECT age, name, occupation FROM freelancers JOIN occupation;
SELECT age AS (Alias) person_age FROM freelancers;
SELECT age, name FROM freelancers UNION SELECT age, name FROM freelancers;
INSERT INTO freelancers (name, age) VALUES ('Fra', 20);
UPDATE people SET name = 'Fra', age = 25;
INSERT INTO freelancers (name, age) VALUES ('Fra', 25) ON DUPLICATE KEY UPDATE age = 25;
DELETE FROM freelancers;
CREATE TABLE freelancers ( name TEXT, age, INTEGER, PRIMARY KEY (name) );
