SQL Operators.

Sql Provides Various Operators To Manipulate And Compare Data Within A Database. Here Are Some Examples Of Sql Operators And Their Usage:

1. Arithmetic Operators: Sql Supports Standard Arithmetic Operators, Such As Addition (+), Subtraction (-), Multiplication (*), And Division (/), Which Can Be Used To Perform Basic Mathematical Operations On Data. For Example, To Calculate The Total Price Of A Product Based On The Quantity And Unit Price, You Can Use The Following Sql Query:

   SELECT quantity * unit_price AS total_price FROM products;

2. Comparison Operators: Sql Supports Various Comparison Operators, Such As Equals To (=), Not Equals To (<> Or !=), Less Than (<), Less Than Or Equal To (<=), Greater Than (>), And Greater Than Or Equal To (>=). These Operators Can Be Used To Compare Two Values Or Expressions. For Example, To Select All Customers Whose Age Is Greater Than 30, You Can Use The Following Sql Query:

   SELECT * FROM customers WHERE age > 30;

3. Logical Operators: Sql Supports Logical Operators Such As And, Or, And Not. These Operators Can Be Used To Combine Multiple Conditions Or Negate A Condition. For Example, To Select All Customers Whose Age Is Greater Than 30 And Whose City Is 'new York', You Can Use The Following Sql Query:

   SELECT * FROM customers WHERE age > 30 AND city = 'New York';

4. Bitwise Operators: Sql Also Supports Bitwise Operators, Such As And (&), Or (|), And Xor (^), Which Can Be Used To Perform Binary Operations On Data. For Example, To Select All Products Whose Stock Quantity Is Greater Than 100 And Whose Unit Price Is Less Than 50, You Can Use The Following Sql Query:

   SELECT * FROM products WHERE stock_qty &gt; 100 AND unit_price < 50;

It's Important To Note That The Usage And Syntax Of Sql Operators Can Vary Depending On The Specific Database Management System Being Used, Such As Oracle, Mysql, Or Sql Server. It's Always Recommended To Refer To The Documentation And Resources Provided By The Database Management System For Specific Information On Syntax And Usage.
