Types of operators working of operators in sql explained

okay, let's dive deep into sql operators. this comprehensive tutorial will cover various types of sql operators, how they work, their precedence, and provide illustrative code examples to solidify your understanding.

**what are sql operators?**

in sql, operators are symbols or keywords that perform specific operations on one or more operands (values, variables, columns, etc.). they allow you to manipulate data, perform calculations, compare values, and build complex conditions in your queries. operators are a fundamental building block for data retrieval, filtering, and transformation within sql databases.

**categories of sql operators**

we can categorize sql operators into several key groups:

1. **arithmetic operators:**
2. **comparison operators:**
3. **logical operators:**
4. **bitwise operators (less common):**
5. **string operators:**
6. **assignment operator:**

**1. arithmetic operators**

arithmetic operators perform mathematical calculations on numeric values. common arithmetic operators include:

* `+` (addition)
* `-` (subtraction)
* `*` (multiplication)
* `/` (division)
* `%` (modulo - remainder of division)

**example:**

**explanation:**

* the `select` statement retrieves data from the `products` table.
* `price * quantity` calculates the total value for each product.
* `price + 10` increases the price of each product by 10.
* `price - 5` discounts the price of each product by 5.
* `price / 2` calculates half the price of each product.
* `quantity % 7` determines the remainder when the quantity is divided by 7.

**2. comparison operators**

comparison operators compare two expressions and return a boolean value (true, false, or unknown/null). they are crucial for filtering data based on specific conditions in `where` clauses.

* `=` (equal to)
* `` (greater than)
* `` (less than)
* `=` (greater than or equal to)
* `=` (less than or equal to)
* `` or `!=` (not equal to)
* `between` (tests if a ...
