![]() 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 In this tutorial, we have shown you how to use the MySQL DATE_FORMAT function to format the date based on a specified format.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. To fix this problem, we have to use an alias that is different from the column name see the following statement: SELECTĭATE_FORMAT(shippeddate, '%W %D %M %Y') 'Shipped date' FROM The reason is that we used shippeddate as the alias for the output of the DATE_FORMAT function, which is a string, the ORDER BY clause took the alias and sorted the orders based on string values, not date values. However, the orders were not sorted correctly. In the query, we selected all orders whose shipped dates were not NULL and sorted the orders by the shipped date. Shippeddate IS NOT NULL ORDER BY shippeddate Code language: SQL (Structured Query Language) ( sql ) MySQL DATE_FORMAT with ORDER BYĭATE_FORMAT(shippeddate, '%W %D %M %Y') shippeddate We formatted the order date, required date, and shipped date of each order based on different date formats specified by the format strings. Orders Code language: SQL (Structured Query Language) ( sql ) To select the order’s data and format the date value, you use the following statement: SELECTĭATE_FORMAT(orderdate, '%Y-%m-%d') orderDate,ĭATE_FORMAT(requireddate, '%a %D %b %Y') requireddate,ĭATE_FORMAT(shippedDate, '%W %D %M %Y') shippedDate Let’s take a look at the orders table in the sample database. The following are some commonly used date format strings: DATE_FORMAT string Year for the week, where the first day of the week is Monday, four digits used with %vĪdd a percentage (%) character to the outputĪdd percentage (%) character to the output Year for the week in four digits where the first day of the week is Sunday often used with %V Week number with leading zero when the first day of the week is Monday e.g., 00,01,02…53įull name of weekday e.g., Sunday, Monday,…, Saturday Weekday in number (0=Sunday, 1= Monday, etc.) Month name with leading zero e.g., 00,01,02,…12ĪM or PM, depending on other time specifiers Hour in 12-hour format without leading zero e.g., 1,2…12įull month name e.g., January, February,…December Hour in 24-hour format without leading zero e.g., 0,1,2…23 Minutes with leading zero e.g., 00, 01,…59ĭay of year with leading zero e.g., 001,002,…366 Hour in 12-hour format with leading zero e.g., 01, 02…12 Hour in 24-hour format with leading zero e.g., 00.23 ![]() Microseconds in the range of 000000.999999 Week number with leading zero when the first day of the week is Sunday e.g., 00,01,02…53ĭay of the month with leading zero if it is 1 number e.g., 00, 01,02, …31ĭay of the month without leading zero e.g., 1,2,…31 ![]() Three-characters abbreviated month name e.g., Jan, Feb, Mar, etc. ![]() Three-characters abbreviated weekday name e.g., Mon, Tue, Wed, etc. The following table illustrates the specifiers and their meanings that you can use to construct a date format string: Specifier The DATE_FORMAT function returns a string whose character set and collation depend on the settings of the client’s connection. See the table below for a list of predefined specifiers. Each specifier is preceded by a percentage character ( % ).
