![]() For example, datetime2(0) will truncate fractional seconds: select CONVERT(datetime2(0), 'T14:18:22. In both cases you can specify the desired precision. The result will have no assumed offset so you should take care to always treat it as UTC: select CONVERT(datetimeoffset, 'T14:18:22.6496978Z', 127) To preserve the timezone offset, use datetimeoffset. In this case you need the datetime2 or datetimeoffset types introduced in 2005. To preserve the timezone offset, use datetimeoffset. datetimeoffset provides time zone support for globally deployed applications. time, datetime2 and datetimeoffset provide more seconds precision. ![]() Use the time, date, datetime2 and datetimeoffset data types for new work. The docs warn strongly against using this type, with a big pink warning at the top of the DATETIME page: The value you tried to parse can't be converted to a datetime without losing precision. For example, datetime is only accurate to 0, 3 or 7 milliseconds. Let’s now see how our Patient table looks.DATETIME and SMALLDATE are legacy types(as in replaced-15-years-ago, don't-use legacy) that have a lot of quirks and limited precision. The DOB column has values in YYYY-MM-DD format, but for the DOD column, you pass the HH:MM: SS (hours: minutes: seconds) information. Notice the difference between the values inserted into the DOB column and the DOD column. The following script inserts some dummy records into the Patient table: INSERT INTO Patient The type of the DOB column is Date, whereas the DOD column has the DateTime data type. The Patient table has 5 columns: Id, Name, Gender, DOB (Date of Birth), and DOD (Date of Death). The following example demonstrates the difference between the Date and DateTime data types.įirst, we are creating a dummy MyDatabase database and one table ( Patient) in it. The Date data type only allows you to store the date information without the time information.The DateTime data type stores the date together with the time information in hours, minutes, and seconds.The difference between the Date and DateTime data types lies in the level of detail in which both the data types store the date information. In SQL Server, you can use either Date or DateTime data type to store dates. It is the YYYY-MM-DD format for dates in SQL Server databases. Thus, the date June 06, 2021, will be stored as. Finally, the day of the month is presented in 2 digits, such as 20. x ) convert ( real, x ) convert ( varchar, x ) convert ( datetime. This function takes the string to convert, the. The month is specified next in 2 digits ranging from 1-12 – e.g., June would be 06. < ' string ' 1 The Transact - SQL language used to write stored procedures has many. Use the PARSE() function to convert a string containing a weekday name, date, and time to the TIME data type. The SQL Server YYYY-MM-DD data format suggests that the year is marked by four digits e.g., 2021. Let’s start! YYYY-MM-DD – the Date Format in SQL Server ![]() ![]() The current article will focus on storing dates in an SQL Server database table and converting different types of dates into the SQL Server format YYYY-MM-DD and vice versa. However, storing and handling such data have their specificities. An SQL Server database can store a variety of data types, such as numbers, text strings, Boolean values, dates, etc.
