SQL Syntax

The operation performed on the databases uses some set rules and guidelines that are known as SQL Syntax. These set rules and guidelines are not case-sensitive. These syntaxes are defined by ISO and ANSI standards.

Let’s look up some important features of Syntax –

  • The syntax is not case-sensitive which means the keywords used in syntax can be easily written in upper or lowercase.
  • The syntax can be written in one single text line or multiple text lines.
  • Some of the databases use (;) after the completion of the syntax. For example – The Microsoft SQL Server uses (;) at the last of the syntax.
  • SQL Statements can easily perform the maximum operations in the database.
  • It depends on relational algebra and tuple relational calculus.

The syntax in SQL helps us perform the operation on the structured data and what information the user wants to access from the database. The syntax/statements in SQL are very basic and very easy to understand but are written with proper rules.

Let’s look at a simple syntax of SQL –

SELECT column_name FROM table_name ;

 

The syntax starts with a keyword and as discussed in most of the databases, the end is done using (;). In this tutorial, we will use (;) at the end of each SQL query or statement.
