3/28/2023 0 Comments Convert string to datetime sql![]() However, you should only use this function if you need to specify how the date and time data should be formatted, because its performance is not as good as CAST(). The CONVERT() function takes three arguments: the new data type, the string to convert, and the (optional) desired format. SELECT d1 AS DATE, CAST(d1 AS DATETIME) AS date as datetime - When converting time to datetime the date portion becomes zero - which converts to January 1, 1900. The CAST() function is ANSI SQL Standard and its performance is better than CONVERT() or PARSE().įinally, you can also use the CONVERT() function. DECLARE d1 DATE, t1 TIME, dt1 DATETIME SET d1 GETDATE() SET t1 GETDATE() SET dt1 GETDATE() SET d1 GETDATE() - When converting date to datetime the minutes portion becomes zero. You can read more in the SQL Server documentation. The string containing the date and time to convert must be in the format of the T-SQL date and time data type. If the argument is a string, it is parsed as Date or DateTime. Solution 2:ĬAST('2 February 2020 11:23:11.1134505' AS TIME ) When you convert a value from one to another data type, you should remember that if you. So in this case you’d need to convert to datetime or smalldatetime. If you’re operating on a string representing a time value that doesn’t store additional data (like the name of the week day), use the CASE() function. Conversion failed when converting date and/or time from character string. ![]() In this case, you should use the PARSE() function, even though it doesn’t have the best performance. PARSE('Niedziela, 2 lutego 2020 11:23:11.1134505' AS TIME USING 'pl-PL' )įor more about culture parameter values, see the official SQL Server documentation. If you’re using a spoken language that’s different from the server language, include the keyword USING and the appropriate culture code. Don’t use the CONVERT() or CAST() functions in this case they also return a TIME data type, but without the day of the week. Notice that the time is only part of this string, which also contains the name of the week day. In our example, the string 'Febru11:23:11.1134505' stores a time value. ![]() ![]() The string should contain a value which represents this data type. This function takes the string to convert, the keyword AS, and a new data type (in our example, TIME). Use the PARSE() function to convert a string containing a weekday name, date, and time to the TIME data type. We need to convert a string containing a weekday name, date, and time to a TIME value. You’d like to convert a string containing a date and time to a TIME value in SQL Server. ![]()
