For conversion from datetime or smalldatetime to character data, see the previous table for the output format.ĥ Hijri is a calendar system with several variations. We recommend specifying four-digit years.ģ Input when you convert to datetime output when you convert to character data.Ĥ Designed for XML use. This allows for the consistent treatment of dates. SQL Server provides the two digit year cutoff configuration option to change the cutoff year used by SQL Server. Many client applications, including those based on Automation objects, use a cutoff year of 2030. That means that SQL Server interprets the two-digit year 49 as 2049 and the two-digit year 50 as 1950. Includes all ( yy) (without century) styles and a subset of ( yyyy) (with century) styles.Ģ The default values ( 0 or 100, 9 or 109, 13 or 113, 20 or 120, 23, and 21 or 25 or 121) always return the century ( yyyy).īy default, SQL Server interprets two-digit years based on a cutoff year of 2049.

We also looked at how you can change the date format with the DATE_FORMAT() function. This article showed you how to convert a date to a string with the CONVERT() and STR_TO_DATE() functions. If you want the day as the nth number of that day, change the d in the format to a capital letter: SELECT DATE_FORMAT('', '%D-%M-%y')Īnd if you want the year in full, change the y to a capital letter: SELECT DATE_FORMAT('', '%D-%M-%Y') If you want the month as the full name of that month, change the m in the format to a capital letter and use the DATE_FORMAT() function: SELECT DATE_FORMAT('', '%d-%M-%y') ![]() How to Use the DATE_FORMAT() to Change the Time Format Next, we'll look at how you can work with date formats with the DATE_FORMAT() function. If you enter the day as the nth day for that date, you have to change the d in the format to a capital letter: SELECT STR_TO_DATE('9th-01-2023', '%D-%m-%Y')Īnd if you enter the month as the abbreviation for that month, you have to change the m in the format to a capital letter: SELECT STR_TO_DATE('9th-JAN-2023', '%D-%M-%Y') N.B.: If you don’t use the same separator for the date and format, you'll get null in return. You can also use a slash ( /) to separate the date and the format: SELECT STR_TO_DATE('', '%d/%m/%Y') You specify the format like this %d-%m-%Y. The format – the format you want the date to get converted to. The STR_TO_DATE() function is another useful function for converting a date or date time. How to Convert Date to String with the STR_TO_DATE() Function You can use a date written as a string, then specify DATE as the data type you want to convert it to: SELECT CONVERT("", DATE) I wrote about them in this tutorial if you'd like to read more.įunctions are not the only parameter you can use as the first argument of the convert function. There are many other functions you can use for working with dates. You can also use SYSDATE() in its place if you want to: SELECT CONVERT(SYSDATE(), CHAR) The second argument, CHAR, is the data type the date got converted to. The query above used the NOW() function to get the current date and time. Here's the CONVERT() function in action: SELECT CONVERT(NOW(), CHAR) the data type – the type of data you want to convert the date to.the date – has to be a string, or with built-in date getters like NOW() or SYSDATE().The CONVERT() function expects two arguments: How to Convert Date to String with the CONVERT() Function How to use the DATE_FORMAT() to Change the Time Format.How to Convert Date to String with the STR_TO_DATE() Function.How to Convert Date to String with the CONVERT() Function. ![]() In this article, I want to show you how to convert a date and datetime to a string in SQL with the CONVERT() and STR_TO_DATE() functions. Almost everything is dependent on a date. You need to be able to work with dates to add timestamps to entries and keep track of when things happen, for example. This is because dates are an important aspect of any SQL and other software-related activities. ![]() When you're working with SQL, you'll need to learn how to format dates properly. ![]()
