REAL(s) One important thing to note here is, – parameter s (Scale) can only be specified if p (Precision) is specified. We use exact numeric data types for integer, decimal, and money. Scale is how many of these digits appear after the decimal point. SELECT ProductID Details First the obvious. In the earlier days of SQL Server, the DECIMAL data type offered flexibility because you could use it to save most numbers. It is denoted as below: 1. decimal [(p [,s])] Where, 1. p stands for Precision, the total number of digits in the value, i.e. nchar (field size), where field size is less than or equal to 255. Let’s move forward and explore Decimal data type in SQL Server. Copy and paste the below query in a new query window and execute it. Length for a numeric data type is the number of bytes that are used to store the number. Precision is the number of digits that the number contains. This article aims to walk you through the SQL Decimal data type and its usage with various examples. Floating point data types are used to store decimal numbers. You can perform this task by using CAST to move the data to and from character-string host variables. A decimal number consists of two parts: the whole part and the fractional part. Like here, decimal (6, 0) behaves differently from data types decimal (6,5) and decimal (3,1) and are considered as three different types. Now that we know how to create this Decimal data type in SQL Server, let’s explore it with numerous examples. A DECIMAL(M,D) column permits up to M - D digits to the left of the decimal point. You can use any SQL Server version installed (starting 2000 or above) to understand this data type. We often use the DECIMAL data type for columns that preserve exact precision e.g., money data in accounting systems. TIME. on both sides of the decimal point 2. s stands for Scale, number of digits after the decimal point The default value of p is 18 and s is 0 and for both these values, the minimum is 1 and the maximum is 38. For this demo, we will insert 2 more rows into this table (shown below). FLOAT(p,s) 8. Let’s work with a very popular mathematical constant – π, aka, Pi that has a value equal to 3.14159 (22/7 in a fraction). It is capable of storing this number:  123456.21, but not 7654321.12. The value of this second argument specifies the precision of the result. The precision defines the total number of decimal digits to store within the number. A Cut and paste from SSMS or Visual Studio would not grab the LF or CR or any data after it. For e.g. Do not define columns with the following SQL/DS and DB2 data types, because they have no corresponding Oracle data type: GRAPHIC. Notice its type is DECIMAL(8,2), meaning there are two decimals within a total of eight digits. In MySQL, the DECIMAL and NUMERIC data types store exact, fixed-point values. Where n is the number of bits that are used to store the mantissa of the float number in scientific notation and, therefore, dictates the precision and storage size.
