![]() ![]() 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 Result: Error converting string value 'Next month' into data type date using culture ''.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. If we provide that same value to the PARSE() function instead, here’s what happens: SELECT PARSE('Next month' AS date) AS Result Here’s an example of a conversion failing: SELECT TRY_PARSE('Next month' AS date) AS Result But if the TRY_PARSE() fails, it returns NULL. If the PARSE() function fails it returns an error. You can also use TRY_PARSE() instead of PARSE() for better error handling. ![]() If we provide that same value to the CONVERT() function instead, here’s what happens: SELECT CONVERT(date, 'Next month') AS Result įor more examples, see CONVERT vs TRY_CONVERT in SQL Server: What’s the Difference? The TRY_PARSE() Function Here’s an example of a conversion failing: SELECT TRY_CONVERT(date, 'Next month') AS Result But if the TRY_CONVERT() fails, it returns NULL. If the CONVERT() function fails it returns an error. You can also use TRY_CONVERT() instead of CONVERT() for better error handling. Result: Conversion failed when converting date and/or time from character string.įor more examples, see CAST vs TRY_CAST in SQL Server: What’s the Difference? The TRY_CONVERT() Function If we provide that same value to the CAST() function instead, here’s what happens: SELECT CAST('Next month' AS date) AS Result Here’s an example of a cast failing: SELECT TRY_CAST('Next month' AS date) AS Result However, if you use the TRY_CAST() function instead, it returns NULL in such cases. ![]() When using the CAST() function, if the cast fails, it returns an error. You can use TRY_CAST() instead of CAST() to provide a smoother way of handling errors. But the PARSE() function can handle this: SELECT PARSE('Thursday, ' AS datetime2)įor more examples, see How to Convert a String to a Date/Time in SQL Server using PARSE(). If you provide the date in this format to the other functions, you’ll get an error. The reason I do this is to demonstrate the benefit that this function has over the others. In this example, I add the weekday as part of the string. ![]() SELECT CONVERT(date, '') AS Result įor more examples, see How to Convert a String to a Date/Time in SQL Server using CONVERT(). Here, we do the same conversion as the previous example, but with the CONVERT() function. SELECT CAST('' AS date) AS Result įor more examples, see How to Convert a String to a Date/Time in SQL Server using CAST(). In this example, we convert the string into a date data type (we specify this by using date as the second argument). In this post I outline six T-SQL functions that allow you to do this.īelow are example of how you can use these functions to convert a string to a date/time data type. If you need to convert a string into a date/time value in SQL Server, you have a number of options. ![]()
