Jul 15, 2019 · This article aims to walk you through the SQL Decimal data type and its usage with various examples. We will also see how we can exercise this data type in SQL Server to help make SQL developer’s job easier.

Mar 31, 2025 · For example, decimal (5,5) and decimal (5,0) are considered different data types. In Transact-SQL statements, a constant with a decimal point is automatically converted into a numeric data value, using the minimum precision and scale necessary.

Dec 12, 2023 · In SQL Server, when you need numbers to be super precise, like in financial calculations, you use the DECIMAL data type. It's like a special box for storing exact numbers and no rounding off! In simpler terms, decimal is SQL Server's way …

In MySQL there are three main data types: string, numeric, and date and time. A FIXED length string (can contain letters, numbers, and special characters). The size parameter specifies the column length in characters - can be from 0 to 255. Default is 1. A VARIABLE length string (can contain letters, numbers, and special characters).

Jun 29, 2009 · In Transact-SQL, numeric is functionally equivalent to the decimal data type. Use the decimal data type to store numbers with decimals when the data values must be stored exactly as specified. The behavior of float and real follows the IEEE 754 specification on approximate numeric data types.

Numeric precision refers to the maximum number of digits that are present in the number. ie 1234567.89 has a precision of 9. Numeric scale refers to the maximum number of decimal places. ie 123456.789 has a scale of 3. Thus the maximum allowed value for decimal (5,2) is 999.99.
