Number Data Types in SQL Server

In SQL Server, there are several number data types that you can use to store numeric data. Here are the commonly used number data types in SQL Server:

  1. INT: Integer data type used to store whole numbers. It can hold values from -2,147,483,648 to 2,147,483,647.
  2. BIGINT: Large integer data type used to store larger whole numbers. It can hold values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
  3. SMALLINT: Small integer data type used to store small whole numbers. It can hold values from -32,768 to 32,767.
  4. TINYINT: Tiny integer data type used to store very small whole numbers. It can hold values from 0 to 255.
  5. DECIMAL(p, s) or NUMERIC(p, s): Fixed-point decimal data type used to store precise numeric values. The 'p' parameter specifies the total number of digits, and the 's' parameter specifies the number of digits after the decimal point. For example, DECIMAL(10, 2) can store numbers up to 10 digits long with 2 decimal places.
  6. FLOAT: Floating-point data type used to store approximate numeric values. It can hold large or small numbers with decimal places. The precision depends on the size specified.
  7. REAL: Floating-point data type used to store single-precision floating-point numbers.
  8. MONEY: Data type used to store monetary values. It stores values up to four decimal places, representing a fixed-point decimal number.
  9. SMALLMONEY: Data type used to store small monetary values. It stores values up to four decimal places, representing a fixed-point decimal number.

It's important to choose the appropriate number data type based on the range and precision requirements of your numeric data. Using the correct data type ensures efficient storage and appropriate handling of your numerical values in SQL Server.
