SQLite Operators

In SQLite, operators are used to perform operations on one or more values. Operators are used in SQL statements to compare, combine and retrieve data from tables. In this tutorial, we will learn about different types of operators and their usage in SQLite.

Syntax

SQLite operators are available in the standard SQL syntax. Some of the common operators used in SQL are:

• Comparison operators: =, !=, <, >, <=, >=
• Arithmetic operators: +, -, *, /, %
• Logical operators: AND, OR, NOT
• Bitwise operators: &, |, ~, <<, >>

Example

Here's an example of a SQL statement that uses operators for various operations in SQLite:

SELECT *
FROM employee
WHERE salary >= 50000 AND department = 'IT'
ORDER BY hire_date ASC;

Output

The above SQL statement will output a list of employees that meet the specified conditions, sorted in ascending order by their hire date.

Explanation

In the above example, we are using the SELECT statement to retrieve data from the employee table. We use the WHERE clause with comparison and logical operators to filter the data based on conditions such as salary and department. Finally, we use the ORDER BY clause to sort the data in ascending order based on the hire date field.

Use

Operators are used in SQL statements to manipulate data to meet specific requirements. They can be used to compare values, perform mathematical calculations, filter data based on conditions, and join multiple tables together.

Important Points

• Operators can be used in various SQL statements, including SELECT, WHERE, and ORDER BY.
• SQLite supports a variety of operators, including arithmetic, comparison, logical, and bitwise operators.
• Be careful when using operators in SQL statements as they can have unintended consequences if not used correctly.
• Always use parentheses to group operators and make the order of operations clear.

Summary

In this tutorial, we learned about the different types of operators available in SQLite and their usage in SQL statements for working with data in tables. We also saw an example of how operators can be used to filter and sort data. By using operators effectively, you can manipulate data to meet specific requirements and retrieve the data you need from your database.
