DatePart Returning Incorrect Value For Weekday (dw)
Feb 18, 2008
Hi All,
In ASP.Net, I am passing a date as a string formatted as yyyymmdd (e.g. 20080219) via an SqlParameter as follows:
aSqlParams(0) = New SqlParameter("@DepartDate", inpDepartDate.Value)
In the Stored Procedure (SP) I am using DATEPART(dw, @DepartDate).
If I execute the SP from within SQL Server and enter a date, formatted as above, as tha value for the Parameter @DepartDate then DatePart returns the correct value (3).
If I use the SP via ASP.Net it returns a value which is 1 less (2).
When I execute the SP manually the resultant EXEC statement uses "@DepartDate = N'20080219'". Can something similar be done in ASP.Net when setting the SqlParameter?
Thank you,

I try to make the following:
select DATENAME(WEEKDAY,[date]) as DAY, sum(earnings) as Earnings
from myTable
where DATENAME(WEEKDAY,[date]
in ('monday','tuesday','wednesday','thursday','friday')
group by DATENAME(WEEKDAY,[date])
order by DAY
this query works very well except the last line. the last line causes SQL-Server to order the days in an alphabetical order.What do I have to do that SQL-Server orders the days according to their natural appearance (monday, tuesday, wednesday, thurs......)

I am/have been having an issue with Data Access from a Sql Server database. I have a class that contains a method called "GetDataReader" which takes in a string for the query. Occasionally, the DataReader returned has completely different columns thus resulting in an error when trying to read the data. Below is a small section of code that actually creates the datareader, opens the connection and executes the reader.SqlCommand cmdReader = new SqlCommand();
SqlDataReader drReturn = null;
try {
// Set the connection for the command object
cmdReader.Connection = new SqlConnection(this._csbGlobal.ConnectionString);
cmdReader.Connection.Open();
// Set the command type
cmdReader.CommandType = Type;
// Set the command text
cmdReader.CommandText = Sql;
// Set the command timeout
cmdReader.CommandTimeout = _iTimeout;
if (Parameters != null) {
// Set the parameters
for (int i = 0; i < Parameters.Count; i++) {
cmdReader.Parameters.AddWithValue("@" + Parameters.GetKey(i), Parameters[i]);
}
}
// Get the return value
drReturn = cmdReader.ExecuteReader(CommandBehavior.CloseConnection);
// Dispose of the command object
cmdReader.Dispose();
cmdReader = null;
} catch (SqlException e) {
this.HandleError(e);
} catch (Exception e) {
this.HandleError(e);
}
// Return the reader
return drReturn;The data access class is created on each page and only used for that page and any usercontrols on that page. I have checked all the datareaders and they are all being closed. I have been fighting with this issue for about a month and a half now. It only seems to happen when there are a lot of people on the site.If anyone has experienced this or konws how to fix it please let me know. Thanks-Jason

I am fairly sure that I am just overlooking something, but the following command is returning some incorrect fields.
SqlDataSource1.SelectCommand = "SELECT ITNBR, (SELECT ITDSC FROM AMFLIBT.ITEMASA WHERE AMFLIBT.ITEMASA.ITNBR = AMFLIBT.ITEMBL.ITNBR) AS ITDSC, SUM(MOHTQ) AS Balance, (SELECT VNDNR FROM AMFLIBT.ITEMASA WHERE AMFLIBT.ITEMASA.ITNBR = AMFLIBT.ITEMBL.ITNBR) AS VENDOR FROM AMFLIBT.ITEMBL WHERE VNDNR = @DDLVNDNR GROUP BY ITNBR, VENDOR"
SqlDataSource1.SelectParameters.Add("ddlvndnr", ddl1.SelectedValue)
I have more code to show, if this looks correct. Just let me know.
Thanks in advance.

SQL Version: SQL2014
PROBLEM: The SQL insert trigger code below is returning incorrect results. In some cases the results returned are from entirely different fields than those specified as the source field in the SET statement. For instance the value returne for the Price_BeforeAdj field does not = 20000000? It returns a NULL. See code below.
OFFENDING CODE:
ALTER TRIGGER [dbo].[xcti_WIPAdjustments_I]
ON [dbo].[budxcWIPAdjustments]
AFTER INSERT AS
BEGIN
SET NOCOUNT ON;
UPDATE budxcWIPAdjustments
[Code] ....

Hi!
Im experiencing problems with datepart(weekday,...) function. In particular with week 54 of 2000... (by the way, dont make a bet about that, because Jan 1st. was saturday (last day of week) and year 2000 was a leap year!!!, so Dec 31 became the one and only case of 54 weeks... in our calendar).
Is there a way I can fix sunday as first day of week, instead using SET DATEFIRST in every procedure? (because "somebody" puts MONDAY as a default in spanish)
Thanx in advance,
Csar.

Hello Guys,
I'm going crazy tring to figure out how to generate a report that execute a Store procedure and then give me a total Per WeekDay and group it by Part Number.
For example my data should look like this
(PartNumber-Monday-Tuesday-Wednesday-Thursday-Friday-Saturday-Sunday-)
The report will give me a list of all available part and the sold sold per part per day.
Thanks in Advance.

Hi,
I have a transaction file containing a year's worth of transactions with a date/time field that tells me when the transaction took place. I'd like to write a view (or perhaps multiple views) that tells me the average number of transactions per weekday.
I've been messing around with DATEPART and I can calculate the *total* number of transactions that took place on a Monday, for example, but I can't figure how to do the *average* number. My problem seems to be calculating the number of Mondays there were in the year. Or overthinking it.
Any suggestions would be greatly appreciated.
Thanks,
Jennifer

In a table, I store an integer to represent a day of the week (1 = sunday ) and then in procedures, compare that to datepart(dw, getdate()) to do alternative tasks on certain days.
If I have the number 1, is there a built in function to convert that to sunday or should one just write a function to do just that?

In my SSRS report i have a date parameter and i want to set to it a default value with a complicated logic. I arrived at this strange behaviour:
Today is May 6th, wednesday. If i use the following expression:
DateAdd("d",Weekday(Today(),DayOfWeek.Sunday),Today())
for the default time picker I get May 9th. If I use exactly the same expression in a textbox in the same report
DateAdd("d",Weekday(Today(),DayOfWeek.Sunday),Today()).ToLongDateString()
I get May 10th! The only thing that changes is the toString. Why are the two values different? I tried with different expressions and the difference arises when i start using Weekday(Today(), somevalue).
The result of Weekday should be independent from regional settings as I am forcing Sunday to be the first day of the week, right?

I have a datetime field in a sql db named "arrdate". For what I am doing I only need to extract the date formatted as mm/dd/yyyy. Can someone give me an example of the proper syntax?
Something like seems like it should work:
SELECT id, DATEPART(mm/dd/yyyy, arrdate)
FROM guest
but of course it doesn't.....

Why would this return a year of 1905: If @tempdate was a varchar
it would return just 2001, but by it being a dateime it returns
the year 1905.
declare @tempdate datetime
select @tempdate = (select datepart(yy,getdate()))
select @tempdate

When it is 'O' (other) was told build a string to parse the year using datepart so that the user can enter the program year (2 digit format). (@Rpt_Yr)
When it is 'M' (monthly) then I am to goto to table tk_prog get the active program

Hi , I am converting a datetime field to a string. The column is called DateScanDate.
This is my query;
SELECT CAST(DATEPART(Year, DateScanDate) AS VARCHAR(4)) + CAST(DATEPART(Month, DateScanDate) AS VARCHAR(2))+
CAST(DATEPART(Day, DateScanDate) AS VARCHAR(2))+ CAST(DATEPART(Hour, DateScanDate) AS VARCHAR(2))+ CAST(DATEPART(Minute, DateScanDate) AS VARCHAR(2))FROM HAAneurysmScan
I would like the month of March to be '03' instead of '3' and the 9th day of the month to be '09' instead of '9'
How can I do this?

Using MS Reporting Services 2005
I have this expression in my field in my table and in my group by expression field
=Monthname(Datepart("m", Fields!CreatedDate.Value))
ok this gives me the month eg July etc
=Datepart("yyyy", Fields!CreatedDate.Value)
ok this gives me the year eg 2006 etc
if I try to add the two together I get the error (not in correct format) obviously as one is numeric and one alpha
=(Monthname(Datepart("m", Fields!CreatedDate.Value) & " " & (Datepart("yyyy", Fields!CreatedDate.Value))))
or I can do this:
=(Datepart("m", Fields!CreatedDate.Value) + (Datepart("yyyy", Fields!CreatedDate.Value)*100))
which gives me 200607
what do I need to do to have this show as
July 2006 etc
thanks

Hi everyone, Im currently using SSRS 2000. I have a report that pulls data since 2001. I used Datepart('m", Fields!Shipped_Date.Value) to break it down into months. It works except that it doesnt separate the year. It'll group all of january together but 2001,2002,2003, etc, together. Then when I used Y to break it down by year, it does break it by year but keeps all the months together.....well what I want is to be able to have it jan 2001, feb 2001, jan 2002, separately group. Hope I didnt confuse anyone. All pointers welcomed.
Thanks,
Abner

I am wanting to set any given @Date parameter to the most current recorded Monday in a table (tblMarketPricing). Would this work:
@Date = Max(Datepart(dw,MktDate) IN 2
I am unsure if you can use Max with the Datepart function.
***If this is not allowed, can anyone suggest anything different that I might try?

ok, following up on my previous post that I marked as answered a little premature. The query below works fine in sql studio:
SELECT id, CONVERT(NVARCHAR(10), arrdate,101) as formatedDate
FROM guest
but when I try to use it in a c# code behind file:
comm = new SqlCommand("SELECT id, CONVERT(NVARCHAR(10), arrdate,101) as formatedDate FROM guest WHERE id = @id", conn);
it bombs??

I am inserting two fields like this (TimeStamp):

The first one needs to be the Date part, the second one needs to be the Time part. Anyone know who to do this? I saw DATEPART in SQL BOL but it didn't really show me.
TIA,

I want to return all records where the date field is
between 09/01/xxxx and 10/31/xxxx. I tried the datepart function but couldn't find a way to combine them. Any solution greatly appreciated.

Hi,
I am having trouble trying to get a "week number" from a date field to store into a numeric table.
I have inserted the following into my DTS ActiveX code;
DTSDestination(15)=DatePart( wk , DTSSource(1) )
When I run the code the following error is shown;
ErrorDescription: Invalid procedure call or argument: ''DatePart'
Q - Does DatePart work in DTS ActiveX ?
Q - Is my syntax correct ?
