SQL Server DataTypes are an important part of database design. They help to ensure that data is stored in an optimal way and that data integrity is maintained. There are many different SQL Server DataTypes, each with its own purpose. In this article, we will take a look at some of the most commonly used SQL Server DataTypes, with examples of how they can be used.The first SQL Server DataType that we will look at is the INT DataType. This DataType is used to store integer values. Integer values are whole numbers that can be positive or negative. The INT DataType can be used to store a range of values, from small numbers to large numbers. The next SQL Server DataType that we will look at is the VARCHAR DataType. This DataType is used to store character data. Character data is any type of data that can be represented by characters, such as letters, numbers, and symbols. The VARCHAR DataType can be usedOne of the most important aspects of any database is its data types. In SQL Server, data types are used to define columns in tables. The data type specifies what kind of data the column can hold, such as integers, decimals, or characters.There are two main types of data in SQL Server: character data and numeric data. Character data includes letters, symbols, and spaces. Numeric data includes numbers that can be used for mathematical operations.SQL Server has many different data types available, including:Integer: A whole number between -2147483648 and 2147483647.-Decimal: A number with a decimal point between -9223372036854775808 and 9223372036854775807.-Date: A date between January 1st, 1753 and December 31st, 9999.-Time: A time between 00:00:00 andData types in SQL Server are used to define the type of data that can be stored in a column. There are different data types available in SQL Server, and each has its own purpose. For example, the INT data type is used to store numeric values, while the VARCHAR data type is used to store character strings. In this article, we'll take a closer look at some of the most common SQL Server data types and provide examples of how they're used.INT: The INT data type is used to store numeric values. Values of this data type can be either positive or negative, but they cannot be fractional or decimal. Examples of INT values include 1, 100, -50, etc.VARCHAR: The VARCHAR data type is used to store character strings. Values of this data type can be any combination of letters and numbers, as well as spaces and other special characters. Examples of VARCHAR values include "A", "abcThere are different data types in SQL Server. These are used to store different types of data such as numeric data, text data, date and time data, binary data, etc. In SQL Server, each column in a table must have a specific data type. The following are the most commonly used SQL Server data types:1. Integer Data Type: This stores whole numbers (no decimal places) between -2147483648 and 2147483647.2. Decimal Data Type: This stores decimal values up to precision 38 with a scale of 0 to 28.3. Float Data Type: This stores floating-point number values with double-precision accuracy (64 bits).4. Date and Time Data Type: This stores date and time values ranging from January 1st, 1753 to December 31st, 9999.5. Binary Data Type: This stores fixed-length binary values up to 8,000 bytes longSQL Server has many different data types available. In this article, we will go over some of the most commonly used data types and provide examples of each.INT: Integer data type is used to store whole numbers. Values stored in this data type can range from -2147483648 to 2147483647.DECIMAL: Decimal data type is used to store numeric values with a decimal point. Values stored in this data type can range from -1038 +1 to 1038 -1.VARCHAR: Varchar data type is used to store character strings. Values stored in this data type can be up to 8,000 characters in length.CHAR: Char data type is also used to store character strings. However, values stored in this data type are fixed-length, meaning that all values must be exactly the same length. Values stored in this data type can be up to 8,000 characters in length.SQL Server Data Types with Examples:Data type is an important property of any column or variable. It defines the kind of data that a column or variable can hold such as numeric, character, and date/time values. In SQL Server, there are different data types that you can use, depending on the kind of data you want to store in your columns or variables.The most commonly used data types in SQL Server are:Integer data type: whole numbers (no decimal places)Character data type: letters and other charactersDecimal data type: numbers with decimal places Date/time data type: stores dates and time values.
