One, in Oracle, when you want to put the string as ' .- the- -  ,: -: $' format into a date format, we can use the To_date function provided by Oracle. The SQL statement is: SELECT to_date ('2011-09-20 08:30:45','YYYY-MM-DD Hh24:mi:ss') from dual; Conversely, you can use the To_char () function to convert dates into strings. The SQL statement is: SELECT to_char (Sysdate,'YYYY-MM-DD Hh24:mi:ss') from dual; Second, in MySQL, the date_format (date, format) function formats the date value according to the format string. %M-month name (January ...
