It’s possible to specify a character set to use for the return value when using the CAST() function.ĬOLLATION(CAST(123 AS CHAR CHARACTER SET utf16)) AS 'utf16',ĬOLLATION(CAST(123 AS CHAR CHARACTER SET latin1)) AS 'latin1',ĬOLLATION(CAST(123 AS CHAR CHARACTER SET big5)) AS 'big5' Once done, you’ll be able to convert between time zones using the time zone names. See How to Set Up Named Time Zones in MySQL for instructions on doing that. If you use 'UTC' and you get an error that reads Unknown or incorrect time zone, it’s probably because your MySQL installation hasn’t yet been configured for named time zones. The only supported time zone is UTC, which can be expressed as either '+00:00' or 'UTC'. | last_modified | CAST(last_modified AT TIME ZONE 'UTC' AS DATETIME) | We can alternatively use 'UTC': SELECTĬAST(last_modified AT TIME ZONE 'UTC' AS DATETIME) | last_modified | CAST(last_modified AT TIME ZONE '+00:00' AS DATETIME) | +-+ Timestamp Valuesīeginning with MySQL 8.0.22, the CAST() function supports retrieval of a TIMESTAMP value as being in UTC, using the AT TIMEZONE operator.ĬAST(last_modified AT TIME ZONE '+00:00' AS DATETIME) In this case, we could use another function, such as STR_TO_DATE() to perform such a conversion: SELECT STR_TO_DATE('15 Mar, 2035', '%e %M, %Y') Here, MySQL apparently couldn’t figure out how to convert this value and returned NULL. However, here’s what happens when we provide an invalid DATE string: SELECT CAST('15 Mar, 2035' AS DATETIME) Therefore MySQL was able to convert the value to a DATETIME data type. In the previous example, we provided a valid DATE string (or DATE literal). In this case, we converted a string to a DATETIME data type.

Here’s another example: SELECT CAST('' AS DATETIME) This cast the value to an unsigned integer, and therefore, the decimal places were removed.

Here’s a simple example that uses the first syntax: SELECT CAST(123.45 AS UNSIGNED INTEGER) Where timezone_specifier is: '+00:00' | 'UTC' Example The optional ARRAY keyword can be used in MySQL 8.0.17 and higher to create a multi-valued index on a JSON array as part of CREATE INDEX, CREATE TABLE, and ALTER TABLE statement.Īs of MySQL 8.0.22, we have the option of using the following syntax: CAST(timestamp_value AT TIME ZONE timezone_specifier AS DATETIME) Where expr is the value to convert, and type is the data type that you want it converted to. The syntax goes like this: CAST(expr AS type ) You provide the value as an argument when you call the function, as well as the type that you’d like it converted to.ĬAST() works similar to CONVERT(), except that the syntax used is slightly different. It takes a value of one type and returns a value of the specified type. Year for the week where Monday is the first day of the week.In MySQL, CAST() is a built in function that converts a value to another data type. Year for the week where Sunday is the first day of the week. Weekday name in full (Sunday to Saturday)ĭay of the week where Sunday=0 and Saturday=6 Week where Monday is the first day of the week (01 to 53).
