Date Data Types in SQL Server

In SQL Server, there are several date and time data types that you can use to store date-related information. Here are the commonly used date data types in SQL Server:

  • DATE: This data type is used to store a date without the time component. It represents the date in the format 'YYYY-MM-DD'. The valid range for the DATE data type is from January 1, 0001, to December 31, 9999.
  • TIME: This data type is used to store a time of day without the date component. It represents the time in the format 'HH:MI:SS.sss'. The valid range for the TIME data type is from 00:00:00.0000000 through 23:59:59.9999999.
  • DATETIME: This data type is used to store both date and time information. It represents the date and time in the format 'YYYY-MM-DD HH:MI:SS.sss'. The valid range for the DATETIME data type is from January 1, 1753, through December 31, 9999.
  • SMALLDATETIME: This data type is similar to DATETIME but with a smaller range and precision. It represents the date and time in the format 'YYYY-MM-DD HH:MI:SS'. The valid range for the SMALLDATETIME data type is from January 1, 1900, through June 6, 2079.
  • DATETIME2: This data type is an extension of DATETIME with increased precision and a larger valid range. It represents the date and time in the format 'YYYY-MM-DD HH:MI:SS.ssssss'. The valid range for the DATETIME2 data type is from January 1, 0001, through December 31, 9999.
  • DATETIMEOFFSET: This data type is used to store date and time along with the time zone offset. It represents the date, time, and time zone offset in the format 'YYYY-MM-DD HH:MI:SS.ssssss OFFSET hh:mm'. The valid range for the DATETIMEOFFSET data type is from January 1, 0001, through December 31, 9999.

These date data types in SQL Server allow you to store and manipulate date and time information in your database accurately. By choosing the appropriate data type, you can ensure that your date-related data is stored and retrieved correctly based on your specific requirements.
