![]() 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. In this blog, we have explored several methods to convert strings to DateTime in MySQL including using functions like STR_TO_DATE(), DATE_FORMAT(), CAST(), CONVERT(), UNIX_TIMESTAMP(), and even regular expressions with substring extraction.Working with dates is a common task in database management, and MySQL provides powerful functions to handle date conversions. ![]() We use the SUBSTRING() function to extract substrings from input_date and then concatenate them in the desired DateTime format. In this query, we assume that input_date is the column containing the custom date format. SELECT CONCAT(SUBSTRING(input_date, 7, 4), '-', SUBSTRING(input_date, 1, 2), '-', SUBSTRING(input_date, 4, 2)) AS converted_date If you have a custom date format, you can extract substrings and rearrange them to match the DateTime format. Method 5: Using Regular Expressions and Substring In this query, the UNIX_TIMESTAMP() function converts the input string ' 12:30:45' to a Unix timestamp, which is then converted to a DateTime using the FROM_UNIXTIME() function. SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(' 12:30:45')) AS converted_date UNIX_TIMESTAMP() can be employed to convert Unix timestamps to DateTime. In the above queries, the CAST() and CONVERT() functions directly convert the input string '' to a DateTime format. SELECT CONVERT('', DATETIME) AS converted_date SELECT CAST('' AS DATETIME) AS converted_date Method 3: Using CAST() or CONVERT()Īnother way to convert strings to DateTime is by utilizing the CAST() or CONVERT() functions. Then, we format the DateTime value using the %Y-%m-%d pattern. Here, we first convert the input string '' to a DateTime using the specified format %m/%d/%Y. STR_TO_DATE() converts the string to a DateTime, and DATE_FORMAT() is then used to format the DateTime value as needed. This method involves using both the STR_TO_DATE() and DATE_FORMAT() functions. Method 2: Using DATE_FORMAT() with STR_TO_DATE() The STR_TO_DATE() function parses the input string accordingly and returns a DateTime value. In the above query, the %Y-%m-%d format specifier indicates that the input string follows the year-month-day pattern. Here's an example: SELECT STR_TO_DATE('', '%Y-%m-%d') AS converted_date It allows us to specify the format of the input string and the desired DateTime format. The STR_TO_DATE() function in MySQL is a powerful tool for converting strings to DateTime. Method 1: Using the STR_TO_DATE() Function In this blog, we will explore multiple ways to convert string to datetime in MySQL. providing step-by-step explanations and code examples for each method.
