Convert string to date in SQLServer

Question

I have the following strings in a table

SEP 21 2009 and OCT 7 2009

Is there any way to convert them to a date format in SQL ? I want to check them as date.

Answer 1

You can use CONVERT() or CAST()

Using CONVERT():

CONVERT ( data_type [ ( length ) ] , expression [ , style ] )

Eg:

SELECT CONVERT(DATETIME,'2014/10/15 11:27:06 PM',20)

See example of CONVERT() in SQL Fiddle

Using CAST():

CAST ( expression AS data_type [ (length)]) 

Eg:

SELECT CAST('MAR 2 1991' as date) as DateValue
SELECT CAST('2013-04-16' AS datetime) AS DateValue

See example of CAST() in SQL Fiddle.
