Hello Everyone,
I have an issue when pulling the data from multiple tables.
Table A has column Date_Created
Table B has column Date_Created
The format is somethine "2012-09-06 13:04:01.067". There is a time difference between columns of 2 tables and I want to compare with dates only and retrieve the data. If I compare both the columns it will not display any data due to time difference. Please let me know how ignore time and compare both columns and retrieve data.
Thanks in advance
Regards,
Pawana Paul

Can you provide the code you are currently using? Hard to tell you what needs to change when don't know what you are currently doing.

You do this with some pretty simple date math. Just use the beginning of the day when comparing.

See this article from Lynn about some common datetime routines. http://www.sqlservercentral.com/blogs/lynnpettis/2009/03/25/some-common-date-routines/[/url]

You might find this useful.

SELECTCAST( GETDATE() AS DATE),

DATEADD( DD,DATEDIFF(DD, 0, GETDATE()),0)

If you just need dates with no time, you should store them that way and even with the correct data type (date for 2008 or higher and datetime or smalldatetime for 2005 and lower).

Hello Lynn,

Thanks for your response.

Below is the syntax of the original query.

SELECT A.COL1, A.COL2, B.COL3, B.COL4 FROM TABLE A JOIN TABLE B ON A.DATE_CREATED = B.DATE_CREATED

Thanks in advance,

does this help?

INNER JOIN TableB AS B ON DATEADD( dd , DATEDIFF( dd , 0 , A.date_created ) , 0 ) = DATEADD( dd , DATEDIFF( dd , 0 , B.date_created ) , 0 )

I agree that if all you want is date then you should use date as the datatype.

See if this works.

SELECT A.COL1, A.COL2, B.COL3, B.COL4 FROM TABLE A JOIN TABLE B ON cast(A.DATE_CREATED as date) = cast(B.DATE_CREATED as date)
