Hello experts,

How would I go about converting a datetime value into a date of format 'M/d/yyyy' (i.e. no zeros so: 1/1/2006 or 11/20/2006)?

Thanks

One way is:

SELECT datepart(mm,DateField) + '/' + datepart(dd,DateField) + '/' + datepart(yyyy,DateField)
FROM TableName

Another is:
SELECT REPLACE(convert(varchar(15),DateField,101),'0','')
FROM TableName

You'll have to test to see which is most efficient for your process.

Actually, neither one is correct...

The first one has problems concatenating int and string types, while the second one cuts out ALL the zeros so '10/20/2005' becomes '1/2/25' which is clearly incorrect...

However, your first one did remind me that I could do it manually using the basic datepart functions.  The correct solution is below, but I'm hoping that maybe there is a better solution somewhere?

Yes, I know this is the correct answer, I'm wondering if there is something better/shorter/easier, since I have to do this multiple times for different fields

=================
SELECT CONVERT(varchar(2),datepart(mm,DateField)) + '/' + CONVERT(varchar(2),datepart(dd,DateField)) + '/' + CONVERT(varchar(4),datepart(yyyy,DateField))
FROM TableName

This is best accomplished using your front-end application and not rely on SQL Server's rudimentary formatting.

actually, this is going to be done in a C# RowFilter on the client side - thats why the formatting has to be handled as such - I built a "search" tool which operates on a similar principal to programs like iTunes, which filters dynamically on all columns (including datetime columns) - right now, it correctly matches dates only if they have zeros in them (such as '6/03/2006') becuse of the way the CONVERT function works (the C# rowfilter operates on the same principals as a SQL 'where' statement.  The code I am using right now is:

dataView1.RowFilter = string.Format("CONVERT(title, System.String) LIKE '*{0}*') OR (CONVERT(dateOrdered, System.String) LIKE '*{0}*') OR (CONVERT(dateDue, System.String) LIKE '*{0}*'", userWord);

Hope that helps explain why I'm looking for this type of formatting and need it to be short...

some thing like this


select cast(month(getdate()) as varchar) +'/'+cast(day(getdate()) as varchar)+'/'+cast(year(getdate()) as varchar)



select cast(month(DateField) as varchar) +'/'+cast(day(DateField) as varchar)+'/'+cast(year(DateField) as varchar)
from yourTable

thats the same as the original answer I gave, just using cast instead of convert, and the shorthand notations for datepart, but thanks :)
