The transaction_date is datetime and date1 is nvarchar.
When I run the script:
Insert into payment(transaction_date)
Select convert (datetime, date1) from dep01
I get the following message:
Server: Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
Thanks in advance, Mike
Hi,
Can someone please explain to me how the datapages in Microsoft SQL Server 2000 works. The pages are supposed to be 8K, that is 8192 bytes of which only 8060 are accessible for data storage (due to overhead).
Now, I currently have a table containing 8 fields. Two of these fields are varchar and should be converted to nvarchar. One of the varchar fields is limited to 255 characters and the other to 4000 characters. When I convert the 255 characters field to nvarchar it works just fine, but when I want to convert the 4000 characters field I get an error from MS SQL saying that it gets to big. Is the error only for the 4000 characters field (which growths to 8000 bytes when using nvarchar instead of varchar) or must the whole table fit into one datapage?
Could a blob maybe solve my problem, or will I face new problems when storing unicode characters in a blob?
Thanks in advance

I uploading an image from a web page into Sql Server 2000 database. I call a stored procedure with the parameter @Flag of type Image. When I tried to pass a null value to this parameter I got the error:"Operand type clash: nvarchar is incompatible with image".I was adding the parameter like this:sqlCmd.Parameters.AddWithValue("@Flag", DBNull.Value);After trying few different things I found a workaround using the following:sqlCmd.Parameters.Add("@Flag", SqlDbType.Image);sqlCmd.Parameters["@Flag"].Value = DBNull.Value;Possibly a bug in the SqlCommand.Parameters.AddWithValue method ?

SELECT Quantity
FROM dbo.BNYForwardsTaxLotsForwards
WHERE investmentType ='Forward Cash'
and Quantity < 0
And I get the following error Msg 245, Level 16, State 1, Line 1..Conversion failed when converting the nvarchar value '-12213949.9' to data type int.
One of my clients decided to put letters into their customers' account numbers. They have a numbering scheme where all temporary accounts have a letter in the account OR are numbered greater than 33000, and all permanent accounts are all digits and less than or equal to 33000. all primary accounts have a NumberSuffix of 000.
Now i am tasked with retrieving all primary, non-temp accounts. I cannot simply do WHERE Number <= 33000 because when it gets to an account containing a letter like "00A01", it craps out and says "Conversion failed when converting the nvarchar value '00A01' to data type int."
So decided to run a filtering query first to filter out all accounts with letters, and then from that dataset select all accounts <=33000.
WITH members (FirstName, LastName, Number, NumberSuffix) AS
(
SELECT
dbo.Entity.FirstName,
dbo.Entity.LastName,
dbo.Entity.Number,
dbo.Entity.NumberSuffix
FROM
dbo.Entity
WHERE
NumberSuffix = 000 AND
Number NOT LIKE '%A%' AND
Number NOT LIKE '%B%' AND
Number NOT LIKE '%C%' AND
Number NOT LIKE '%D%' AND
Number NOT LIKE '%E%' AND
Number NOT LIKE '%F%' AND
Number NOT LIKE '%G%' AND
Number NOT LIKE '%H%' AND
Number NOT LIKE '%I%' AND
Number NOT LIKE '%J%'
)
SELECT *
FROM
members
WHERE
Number <= 33000
ORDER BY
Number
when i do this, i get the same error for some reason. Yet when i execute this at the end instead:
SELECT *
FROM
members
WHERE
Number LIKE '%A%'
ORDER BY
Number
i get an empty set (meaning it actually does get filtered).
but somehow it still able to participate in a range comparison?
WHY??
thanks,

Using backup and restore.
Note I had the same issue after restoring the production database on my local server SQL2000->SQL2000.
The problem was solved by restoring master and msdb from the production. But I can't do this on the SQL2005.
This is not a collation issue as I have ensured collation is the same on all databases including the system ones.
The database in question makes extensive use of user defined data types (Which I have recreated on the destination server).
Can anyone please help?

Hi,
I can't seem to fix the following error in my stored procedure.
Error Message: Conversion failed when converting the nvarchar value '1007-001' to data type int.
The line of code in my stored procedure that seems to be the problem is the following:
CASE WHEN [Order Details].[Job No] IS NULL THEN [Orders].[Order No] ELSE [Order Details].[Job No] END
Order No has a data type of INT and Job No has a data type NVARCHAR(8). In the above case statement i'm not trying to convert anything but just display a column depending on the out come of the case statement. If anyone knows how to get around this error you help would be very welcome.

I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.
I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

hi all,
i have created a table with image field in it. Now i just want to store a jpeg file in it but not finding any way to do so.
how can i store any image ? what are the steps???????
thanx in advance
Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.
I have learned lots of informative thing from your forums. I have little problem regarding “Display image from SQL Server on ASP.NET� I have done it and image display on my page from SQL Server. I have cleared you here I have adopt two different methods which are following for displaying picture.
1.Response.BinaryWrite(rd("picture"))
2.image.Save(Response.OutputStream, ImageFormat.Jpeg)
but in both above methods I have faced little problem when image display on my page all other information can not display and I also want to display picture on my specific location on the page. My second question is can use any web control like “Image1� to display image from SQL Server where my pictures are stored.
Hope you will help me.

Hi Experts,
I am extracting data from SQL Server 2005 to flat file destination. I am using SQL Command to specify the data selection query. One of my query uses Replicate function to derive a column value. When I execute this package it fails with the error "Data conversion failed. The data conversion for column "value" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page".
The reason for the problem is that, it is taking the InputColumnWidth of the flat file destination as 8000 and I specified the OutputColumnWidth as 4.
If I change the OutputColumnWidth to 8000, it is working without any error but resulting in the column width of 8000.
I tried using DerivedColumn Transformation's Type cast and DataConversion Transformation but still I am getting the same error in the respective Transformation components.
Can anyone suggest how to solve this issue.
