![]() We will use the SELECT statement and an alias called ‘Result’. Suppose you have the string – ‘15 02 2021’ where 15 is the day, 02 is the month and 2021 represents the year. Let us kick things off with a couple of basic examples. %x – Year for the week where Monday is the first day of the week.%X – Year for the week where Sunday is the first day of the week.%w – Day of the week where Sunday=0 and Saturday=6.%W – Weekday name in full (Sunday to Saturday).%v – Week where Monday is the first day of the week (01 to 53).%V – Week where Sunday is the first day of the week (01 to 53).%u – Week where Monday is the first day of the week (00 to 53).%U – Week where Sunday is the first day of the week (00 to 53).%r – Time in 12 hour AM or PM format (hh:mm:ss AM/PM).%m – Month name as a numeric value (00 to 12).%M – Month name in full (January to December).%e – Day of the month as a numeric value (0 to 31).%d – Day of the month as a numeric value (01 to 31). ![]() %D – Day of the month as a numeric value, followed by suffix (1st, 2nd, 3rd, …).%b – Abbreviated month name (Jan to Dec).%a – Abbreviated weekday name (Sun to Sat).The ‘format’ can be one or a combination of the following – We could change our example above to convert the value '' to the latin1 character set as follows: mysql> SELECT CONVERT('techonthenet.‘format’ is the format to use while formatting the string to a date value. This CONVERT example takes the value '' and converts it from the current character set to the utf8 character set. For example: mysql> SELECT CONVERT('' USING utf8) Let's look at how to use the CONVERT function to convert between character sets. The second syntax for the MySQL CONVERT function allows you to convert a value from one character set to another. This CONVERT example takes the value '4' and converts it as a BINARY datatype with the binary string value of '4'. For example: mysql> SELECT CONVERT('4', BINARY) This CONVERT function example shows how to convert a value to a BINARY type. This CONVERT example takes the value 4-5 and converts it as an UNSIGNED datatype with the value of 18446744073709551614. update mytable again to populate the newdate column with the string values currently stored in the old text date column. For example: mysql> SELECT CONVERT(4-6, UNSIGNED) You can create a new column of type DATETIME then you update it with your converted data from your TEXT column using the datetime conversion functions from mysql. This CONVERT function example shows how to convert a value to an UNSIGNED type. This CONVERT example takes the value 4-5 and converts it as a SIGNED datatype with the value of -2. For example: mysql> SELECT CONVERT(4-6, SIGNED) This CONVERT function example shows how to convert a value to a SIGNED type. This CONVERT example takes the value 125 and converts it as a CHAR datatype with the value of '125'. Seems to me you should have stored the date as a DateTime column in the first place. So I'm expecting the converted datetime should be compatible with comparison operators (< and >).After converting it, I have to compare this with another date. For example: mysql> SELECT CONVERT(125, CHAR) I want to convert the string 'T14:39:00.000' into datetime format in my sql select query. This CONVERT function example shows how to convert a value to a CHAR type. This CONVERT example takes the value '08:14:57' and converts it to a TIME datatype. For example: mysql> SELECT CONVERT('08:14:57', TIME) This CONVERT function example shows how to convert a value to a TIME type. This CONVERT example takes the value ' 08:14:57' and converts it to a DATETIME datatype. For example: mysql> SELECT CONVERT(' 08:14:57', DATETIME) This CONVERT function example shows how to convert a value to a DATETIME type. This CONVERT example takes the value '' and converts it to a DATE datatype. For example: mysql> SELECT CONVERT('', DATE) Let's look at how to use the CONVERT function to convert a value to a DATE type. The first syntax for the MySQL CONVERT function allows you to convert a value from one datatype to another datatype. Syntax STRTODATE ( string, format) Parameter Values Technical Details Works in: From MySQL 4. ![]() Let's look at some MySQL CONVERT function examples and explore how to use the CONVERT function in MySQL. Definition and Usage The STRTODATE () function returns a date based on a string and a format.
