SQL Server Tutorial

SQL Server stands for Structured Query Language is a nonprocedural language, which makes RDBMS (Relational Database Management Systems) possible.

The SQL Server Query is the set of instructions used to interact with a relational database. SQL statements are aimed to Insert, Update or Manipulate, and Extract data from the Relational Database Management Systems.

In this SQL Tutorial, we will show the best way to learn SQL Server and explain everything about it. Which includes: How to create, alter, delete databases, and tables. DML, DDL statements, Built-in functions etc.

Best Way to Learn SQL Tutorial

This section of SQL Tutorial explains about the creating Databases, Tables. Next, inserting, updating, selecting data from tables using filters, sorting, etc.

A string in Sql is a group of charters stored in Varchar or Nvarchar data type, which is useful to store names, product descriptions, etc. SQL Server String functions enable you to manipulate the string data by searching for the given string and replacing it or adding so on. The following are the list of available string function in SQL Server:

SQL Tutorial on Aggregate Functions

SQL Server Aggregate functions are used to extract the aggregated or high-level data. For instance, total sales in a region, product sale by country, etc. To use these aggregate functions, you have to use the Group By Clause for the non aggregated columns. Otherwise, it will throw an error.

If you want to use any expressions to restrict the records, then use Having Clause, not the Where Clause. The below section will show you the list of aggregate function available in SQL Server

Learn SQL Date Functions

In general, the Date will store in dd-mm-yyyy hh:mm:ss format or any other system-specific format. There are some cases where we have to extract individual parts such as Month, Month Name, Year, Day, etc. In other times, we may have to format the Date, add or subtract a few days from the original date. In all these scenarios, we can use the built-in standard SQL Server date functions to manipulate the Date.
