Transact SQL :: Get Week Number From DateTime Field?

Aug 21, 2015

Any easier way to do what I am trying, without having a table with all the dates and week numbers.

Scenario: Week number of a DateTime Field where the year does not start on January 01st but April 1st to 31 Mach.

Issue: A week always starts on a Monday so if the 1st is on Tuesday, the first week is Tuesday – Sunday, if the 1st April is on Friday, the 1st week is Friday – Sunday and 7 day periods from there.

CREATE
TABLE [dbo].[DailyCanx](
[ID] [int] IDENTITY(1,1)
NOT NULL,
[DateCancelled] [datetime] NULL
)
ON [PRIMARY]

[code]....

I could create a table with all the start date and end dates of all the week numbers but I think there must be a better way. using SQL Server 2008 R2.

So I need to select and average a whole bunch of data by week. Currently, I group by:

Since the first day of the year was a monday, it sets the weeks as monday-monday. I need to set the weeks to be Thursday 7pm to Thursday 7pm. How can this be achieved? Thanks.

Informix Date Type Field To SQL Server Datetime Field Error

Oct 17, 2007

I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part

I tried a couple of things:

Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.

Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.

What options do I have that will work?
