![]() Because the number 21 matches with the %d specifier, the function takes 21 as the day value. First, it attempts to find a match for the %d format specifier, which is a day of the month (01…31), in the input string.| STR_TO_DATE( '21,5,2013', '%d,%m,%Y') |ġ row in set (0.00 sec) Code language: JavaScript ( javascript )īased on the format string ‘%d, %m, %Y’, the STR_TO_DATE() function scans the ‘21,5,2013’ input string. SELECT STR_TO_DATE( '21,5,2013', '%d,%m,%Y') Code language: SQL (Structured Query Language) ( sql ) 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 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. Refer to the DATE_FORMAT function for the list of format specifiers. The format string may contain literal characters and format specifiers that begin with a 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. For example, %d for day, %m for month and %y for year. fmt: This is the format string that includes format specifiers.str: This is the input string that you want to convert.Here’s the syntax of the STR_TO_DATE() function: STR_TO_DATE(str,fmt) Code language: SQL (Structured Query Language) ( sql ) The STR_TO_DATE() converts a string into a date value based on a specified format string. Introduction to MySQL STR_TO_DATE function Depending on the requirements and the format of the input strings, you can choose the most suitable method.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, or datetime value. The STR_TO_DATE(), DATE_FORMAT(), DATE(), CAST(), and CONVERT() functions are powerful tools for handling date conversions efficiently. In this blog, we explored multiple methods to convert strings to dates in MySQL. SELECT CONVERT('', DATE) AS converted_date īoth CAST() and CONVERT() functions convert the input string ' ' to a date data type. SELECT CAST('' AS DATE) AS converted_date MySQL allows explicit casting of strings to dates using either the CAST() or CONVERT() functions. ![]() Method 4: Using CAST() or CONVERT() Function The DATE() function implicitly converts the string '' to a date data type, extracting the date part and discarding the time portion (if any). MySQL can perform implicit conversions between date formats and strings using the DATE() function. Here, we first use STR_TO_DATE() to convert the string ' 08-01-2023' to a date, assuming the format is ' MM-DD-YYYY.' Then, DATE_FORMAT() is used to convert the date back to the desired format ' YYYY-MM-DD.' Method 3: Using DATE() Function with Implicit Conversion We can combine this with the STR_TO_DATE() function to achieve the desired conversion. ![]() The DATE_FORMAT() function allows us to convert a date or a string into a specific format. In this example, the format string ' %Y-%m-%d' is used to indicate that the input string should be interpreted as a date in the format " YYYY-MM-DD." The function successfully converts the string ' ' to a date data type. SELECT STR_TO_DATE('', '%Y-%m-%d') AS converted_date The function takes two arguments: the input string and the format string. MySQL provides the STR_TO_DATE() function to convert a string to a date format based on a specified format string. In this blog, we will explore multiple methods to convert strings to dates in MySQL. Converting strings to dates is crucial when dealing with date data stored as strings or importing data from external sources. Working with dates is a common task in database management, and MySQL provides powerful functions to handle date conversions.
