![]() ![]() The following statement converts a string into a DATE value. Let’s look at some examples of using STR_TO_DATE() function to convert strings into a date and/or time values The STR_TO_DATE() function is very useful in data migration that involves temporal data conversion from an external format to MySQL temporal data format. ![]() Check it out the DATE_FORMAT function for the list of format specifiers. The format string may contain literal characters and format specifiers that begin with percentage (%) character. The STR_TO_DATE() function scans the input string to match the format string. If the input string is illegal, the STR_TO_DATE() function returns NULL. The STR_TO_DATE() function may return a DATE, TIME, or DATETIME value based on the input and format strings. The STR_TO_DATE() converts the str string into a date value based on the fmt format string. The following illustrates the syntax of the STR_TO_DATE() function: STR_TO_DATE(str,fmt) Code language: SQL (Structured Query Language) ( sql ) ![]() Introduction to MySQL STR_TO_DATE function In this tutorial, you have learned how to convert a string to a datetime using the CONVERT() and TRY_CONVERT() functions.Summary: in this tutorial, we will show you how to use the MySQL STR_TO_DATE() function to convert a string into a date time value. 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. ![]()
