![]() ![]() IE enforces the JavaScript standard, and simply doesn’t recognize the DATETIME format as being a valid date. In doing most web development, I have been using Chrome to test the pages first because I find Chrome’s developer tools much better than those with Internet Explorer, even though the site will eventually have to be compatible with IE 8+.Īpparently, when taking a SQL DATETIME (which is in the format “yyyy-mm-dd hh:mm:ss.ms”) string and creating a new JS Date, Chrome will take it directly, but IE is more strict. I have been working on some JavaScript that will take a date (in the DATETIME format) from SQL Server and create a new JavaScript Date object using this date. In this tutorial, you have learned how to convert a string to a datetime using the CONVERT() and TRY_CONVERT() functions.It should come as no surprise to anyone who has developed for multiple browsers that each one has its own quirks when it comes to enforcing standards, whether they be CSS, HTML5, or even JavaScript. The CONVERT() and TRY_CONVERT() functions can convert United States datetime format (month, day, year and time) by default, therefore, you don’t need to specify style 101: SELECT TRY_CONVERT( DATETIME, '12-31-2019') ![]() Note that the CONVERT() function can also convert an ISO date string without delimiters to a date value as shown in the following example: SELECT CONVERT(DATETIME, '20190731') result This example shows how to use the CONVERT() function to convert strings in ISO date format to datetime values: SELECT CONVERT(DATETIME, '') The TRY_CONVERT() function, on the other hand, returns NULL instead of raising an error if the conversion fails: SELECT TRY_CONVERT(DATETIME, '', 102) result Ĭode language: SQL (Structured Query Language) ( sql ) Converting a string in ANSI/ISO and US date format to a datetimeīoth CONVERT() and TRY_CONVERT() function can recognize ANSI/ISO and US formats with various delimiters by default so you don’t have to add the style parameter. The following is the error message: The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. If the conversion fails, the CONVERT() function will raise an error: SELECT CONVERT(DATETIME, '', 102) result This example uses the CONVERT() function to convert a string in ANSI date format to a datetime: SELECT CONVERT(DATETIME, '', 102) result The main difference between CONVERT() and TRY_CONVERT() is that in case of conversion fails, the CONVERT() function raises an error while the TRY_CONVERT() function returns NULL. SQL Server provides the CONVERT() function that converts a value of one type to another: CONVERT(target_type, expression )Ĭode language: SQL (Structured Query Language) ( sql )īesides the CONVERT() function, you can also use the TRY_CONVERT() function: TRY_CONVERT(target_type, expression ) Introduction to CONVERT() and TRY_CONVERT() functions Summary: in this tutorial, you will learn how to convert a string to a datetime in SQL Server using the CONVERT() and TRY_CONVERT() function. ![]()
