SQL Course with Certificate: Mastering SQL for Database Management!

In this modern, information-driven world, enhancement in data manipulation skills is a must, and an SQL Course With Certificate is the perfect way to start. Structured Query Language, commonly called SQL, is a language used for maintaining and manipulating relational databases. 

SQL allows for the efficient execution of user requests to access, modify, and control data. In fact, its role in database management cannot be overstated, as it constitutes the backbone of manipulation across various industries, from finance to healthcare.


Types of SQL Statements


SQL comprises many types of statements that perform different kinds of operations in database management:


Data Query Language(DQL): DQL statements are primarily used for SELECT statements, which enable the access of data from a database.


Data Definition Language (DDL): These are CREATE, ALTER, and DROP statements. These statements provide the user with the means to create tables, alter the existing ones and even drop them completely.


Data Manipulation Language (DML): These include INSERT, UPDATE, and DELETE statements that allow the user to modify data previously created in a database.


Data Control Language (DCL): This includes statements such as GRANT and REVOKE. These statements specify controls on database access by granting security and permission to users.


Common SQL Functions


SQL provides a set of built-in functions that ease manipulation and analysis of the data:

Aggregate Functions: COUNT, SUM, and AVG are types of functions that enable the user to perform calculations over a set of values and return one scalar value.

String Functions: The SQL string functions consist of the CONCAT function, which connects several strings into one string. Likewise, a SUBSTRING function pulls out a part of a string based on start positions and lengths.

Date Functions: SQL has functions that are related to dates. It has the NOW function, which returns the current date and time, and DATEADD, which allows users to specify which date to add daily, monthly, or yearly.
