![]() The second argument is the format, which works in the same way as it does in the STR_TO_DATE function. In our example, the first argument of the DATE_FORMAT function is the date resulting from the STR_TO_DATE function. The general syntax of the DATE_FORMAT function is: DATE_FORMAT(date, format) To extract only the time, we have to add the DATE_FORMAT function to the query above. Now we have the value in the DATETIME data type. The result of this query should look like this: 12:30:20. You can find more parameters in official documentation for MySQL. %T: Time in the 24-hour format (hh:mm:ss).%Y: Year as a 4-digit numeric value (yyyy).%m: Month as a numeric value from 01 to 12.%d: Day of the month as a numeric value from 01 to 31.%W: Weekday name from Sunday to Saturday.In our case, we use the following parameters: The second argument specifies the format of the string. The first argument of this function is the string we want to convert. The syntax for this function is as follows: The purpose of the STR_TO_DATE function is to convert a text string to a datetime format. To do this, we use the STR_TO_DATE function. To illustrate the process more clearly, we will explain this in two parts.įirst, we have to convert the string to a date value. You want to extract only the time part, '12:30:20'. You have a string value that looks like this: 'Wednesday, 10 February 2021, 12:30:20'. Python : How to convert a timestamp string to a datetime object using datetime.You want to extract the time from a string value in MySQL.Python : How to convert datetime object to string using datetime.strftime().For example, from datetime import datetime To handle this kind of scenario, either pass the correct format or use the try/except. Both the datetime string and format are not compatible, so it raised a ValueError. Here we the string contains the date and time information in format’ MM/DD/YY HH:MM:SS’, but we passed the format string as ‘%d-%m-%Y %H:%M:%S’. Output: ValueError: time data ' 11:12:13' does not match format '%d-%m-%Y %H:%M:%S' For example, from datetime import datetimeĭatetime_obj = datetime.strptime(datetime_str, '%d-%m-%Y %H:%M:%S') If the datetime string and the format string passed in strptime() function are not compatible, then it can cause a ValueError. Based on that, it parses the string and constructs a datetime object.Ĭonvert string to datetime and handle ValueError Then it checks how these format codes are organized in the string, like what characters they are separated by and what their positions are. %S – Represents the seconds like 01,02,…60.%M – Represents the minutes like 01,02,…60. ![]()
