MySQL equivalent for MSSQL"s DATENAME

Please help!

I am hunting high and low for an equivalent function for MSSQL's
DATENAME function. Here's the spec on the function from MSSQL's Books
Online:

DATENAME
Returns a character string representing the specified datepart of the
specified date.

Syntax
DATENAME ( datepart , date )

Arguments
datepart

Is the parameter that specifies the part of the date to return. The
table lists dateparts and abbreviations recognized by Microsoft=AE SQL
Server=99.

Datepart Abbreviations
year yy, yyyy
quarter qq, q
month mm, m
dayofyear dy, y
day dd, d
week wk, ww
weekday dw
hour hh
minute mi, n
second ss, s
millisecond ms


The weekday (dw) datepart returns the day of the week (Sunday, Monday,
and so on).

Is an expression that returns a datetime or smalldatetime value, or a
character string in a date format. Use the datetime data type for dates
after January 1, 1753. Store as character data for earlier dates. When
entering datetime values, always enclose them in quotation marks.
Because smalldatetime is accurate only to the minute, when a
smalldatetime value is used, seconds and milliseconds are always 0. For
more information about specifying dates, see datetime and
smalldatetime. For more information about specifying time values, see
Time Formats.

If you specify only the last two digits of the year, values less than
or equal to the last two digits of the value of the two digit year
cutoff configuration option are in the same century as the cutoff year.
Values greater than the last two digits of the value of this option are
in the century that precedes the cutoff year. For example, if two digit
year cutoff is 2049 (default), 49 is interpreted as 2049 and 2050 is
interpreted as 1950. To avoid ambiguity, use four-digit years.

Return Types
nvarchar

Remarks
SQL Server automatically converts between character and datetime values
as necessary, for example, when you compare a character value with a
datetime value.

Examples
This example extracts the month name from the date returned by GETDATE.

SELECT DATENAME(month, getdate()) AS 'Month Name'

Here is the result set:

Month Name
------------------------------
February

MySQL's date_format() function appears to do similar things to
DATENAME. The format string is very different. If it's a constant
string (e.g. you're always going after the full month name), it
should be easy to translate.

Then I would have to say you did not search very hard :)

http://dev.mysql.com/ look at the documentation and search for the keyword date

MySQL supports the ANSI standard CAST function that can accomplish the same thing.
