SQL Server CONVERT Datetime to String in MySQL

In SQL Server, you can use CONVERT function to convert a DATETIME value to a string with the specified format. In MySQL, you can use DATE_FORMAT function.

SQL Server:

  -- 3rd parameter specifies 121 style (ODBC 'YYYY-MM-DD HH:MI:SS.FFF' format with milliseconds)
  SELECT CONVERT(VARCHAR, GETDATE(), 121);
  # 2012-11-29 19:18:41.863

MySQL:

  -- Specify string format using format specifiers
  SELECT DATE_FORMAT(NOW(), '%Y-%m-%d %T.%f');
  # 2012-11-29 19:18:41.000000

Mapping SQL Server Datetime Style to MySQL Format

When you convert CONVERT function to DATE_FORMAT you have to map the SQL Server style to the appropriate format string in MySQL:

SQL Server Style		MySQL Format String	Output Example
101	US - MM/DD/YYYY	'%m/%d/%Y'	11/29/2012
103	British/French - DD/MM/YYYY	'%d/%m/%Y'	29/11/2012
108	Time - HH:MI:SS	'%T'	18:21:11
111	Date - YYYY/MM/DD	'%Y/%m/%d'	2024/07/27
112	Date - YYYYMMDD	'%Y%m%d'	2017-04-06
113	European - DD MON YYYY HH:MI:SS.FFF	'%d %b %Y %T.%f'	15 Jul 2022 21:24:51:707
121	ODBC - YYYY-MM-DD HH:MI:SS.FFF	'%Y-%m-%d %T.%f'	2012-11-29 18:21:11.123
20	ODBC - YYYY-MM-DD HH:MI:SS	'%Y-%m-%d %T'	2012-11-29 18:21:11

Conversion examples:

SQL Server	MySQL
CONVERT(VARCHAR, GETDATE(), 101)	DATE_FORMAT(NOW(), '%m/%d/%Y')
CONVERT(VARCHAR, GETDATE(), 103)	DATE_FORMAT(NOW(), '%d/%m/%Y')
CONVERT(VARCHAR, GETDATE(), 108)	DATE_FORMAT(NOW(), '%T')
CONVERT(VARCHAR, GETDATE(), 111)	DATE_FORMAT(NOW(), '%Y/%m/%d')
CONVERT(VARCHAR, GETDATE(), 112)	DATE_FORMAT(NOW(), '%Y%m%d')
CONVERT(VARCHAR, GETDATE(), 113)	DATE_FORMAT (NOW(), '%d %b %Y %T.%f')
CONVERT(VARCHAR, GETDATE(), 121)	DATE_FORMAT(NOW(), '%Y-%m-%d %T.%f')
CONVERT(VARCHAR, GETDATE(), 20)	DATE_FORMAT(NOW(), '%Y-%m-%d %T')
