Image data type Size

I need to store images in MS SQL. I have the upload procedures and stuff but I'm missing the point about the image data type size.

It is supposed to be able to store up to 2Gb!!! but when I declare the data field image I can't specify the max size for the field and by default is 16 !!

16 bytes!! what can I do with that?
How can I insert a file?

Please helpThe pointer to the data is the only thing stored in this database row. The data is stored elsewhere and can be up to 2G. You don't get to specify the size.

Bill|||Thanks for the reply!

But that leads me to this question: How can I write the Insert Statement for the image field?

create table ImgTest (
imgID Int,
imgFName varchar(30),
imgFType varchar(30),
imgFile image
)

All I got so far is a procedure in vb net that tryes to insert a byte array asigned to parameter value:

Insert Into ImgTest Values (1, 'file.jpg', 'image file', @.bytearray)

That's where I'm having trouble because it returns the error: "Data will be truncated" or something like that. I guess it's because it tryes to store the file in the 16bytes that are reserved for the pointer...

Oh.. I'm so lost..

Thank you!sql

Im new to stored Procedures

I create my store proc. I want to give it a parameter AccNmbr and I want it to return to me the total of the columns SubNmbr in total variable; total is gonna be an output. So I do this in my Stored Proc:

Create Procedure dbo.totalSub
@.AccNmbr bigint,
@.total bigint out
AS
Select @.total=sum(SubNmbr) where AccNmbr=@.AccNmbr
return

Go

When I run the proc it tells me that parameter total was not provided. I also tried with return (instead of Return @.total)
it always tells me missing total parameter. But I want total to be my result, not my input. Only AccNmbr is my input.
Thanks a lot for your help.

When you create this Stored Procedure, you have 2 input parameters. Either you can specify one as output, or just have 1 input... Here's a modification that will do what it seems you were doing. You also missed what table you were pulling the results from, that is mentioned by "FROM TABLE".

Here ya go:

Create

Procedure dbo.totalSub
@.AccNmbr int,
AS
Selectsum(SubNmbr)FROMTABLEwhere AccNmbr=@.AccNmbr
Go

You re right, I correct my stuff as shown bellow:

My stored procedure works perfectly when I run Query Analyser, but when I run my VB program I get the eror: I get the message : An SqlParameter with ParameterName'@.total' is not contained by this SqlParameterCollection.

Here is my stored Proc and my VB program is right below

I- Stored Proc:

CREATE PROCEDURE dbo.totalsub
@.account bigint,
@.total bigint output
AS
select total=sum(SubPhnNmbr) from tblsub whereSubAccNmbr=@.account
return
GO

II- And my pogram in VB is:

Dim totsub As Int64
Dim cm As New SqlCommand
Dim cn As New MyConnection
cn.open
'my connection is defined by me don't worry about it
cm.CommandType = CommandType.StoredProcedure
cm.CommandText = "totalsub"
cm.Connection = cn
Dim pm As SqlParameter
pm = cm.Parameters.Add(New System.Data.SqlClient.SqlParameter("@.Account", System.Data.SqlDbType.BigInt))
pm.Value = 100000165
pm = cm.Parameters.Add(New System.Data.SqlClient.SqlParameter("total", System.Data.SqlDbType.BigInt, 4))
pm.Direction = ParameterDirection.Output
totsub = cm.Parameters("total").Value
cm.ExecuteScalar()
totsub = cm.Parameters("total").Value

I also tried using @.total instead of total and I tried ParameterDirection.ReturmValue instead of ParameterDirection.Output

No Luck, thanks a lot for help
