This is a SQL question...how?

Hello there,

I have an application in VB.Net in which I import data from Excel files to SQL server database.

I'm trying to retrieve a table in Excel 2007 worksheet, which has more than 255 columns, using Ado.net 2

The problem lies in the "Select * from [Sheet1$]" statement, which will only pick a maximum of 255 columns from the Excel sheet, even though the sheet has around 260 columns.

here is my code for your review:

'*****************************************************************************

'The connection string.
Dim xlCon As String = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & lblImportFile.Text & _
";Extended Properties=""Excel 12.0;HDR=YES"""

'Excel "SELECT" statement
XlsSQL = "Select * from [Sheet1$]"

'Declare and instantiate the connection object.
Dim con As New OleDbConnection(xlCon)

'Declare and instantiate the command object.
Dim com As New OleDbCommand()

'Declare and instantiate a DataAdapter which fill the dataset with data.
Dim da As New OleDbDataAdapter

'Add values to the command object's properties.
With com
.Connection = con
.CommandType = CommandType.Text
.CommandText = XlsSQL
End With

With da
.AcceptChangesDuringFill = False
.SelectCommand = com

'Add data to the dataset.
.Fill(dsXLData, "Ratings")
End With

da.Dispose()
con.Dispose()

This is a limitation that you will have to work around. Maybe you could split the upload into 2 files, each with 130 columns.

However, maybe you should consider using a different file format. A text-based flat file wouldn't have the same problems.

Thanks Paul for your reply.

I take it that you are dead sure that no way on earth could a "Select" statement pick more than 255 columns. Right?

Your suggestion of splitting the upload seems to be the best work-around for that limitation.

Thanks again for your help. Greatly apprecaited.

Hi again Paul,

I followed your suggestion and split the uploads.

The problem now in the rows of second upload, instead of adding them to the same rows of first upload, they are bieng added on top of them.

To explain further, the excel sheet has 280 columns x 100 rows. In the first upload, I fill the dataset with 255 clms x 100 rows. In the second upload, I fill the dataset with 25 clmns x 100 rows, but in the end result I get a dataset with 280 clmns (cool) and 200 rows (Not cool)

Is there any way perhaps in a galaxy not far away Big Grin | :-D

, that I enforce the dataset to add the rows of the second upload into those of the first upload

Greatly appreciate your help

Perhaps this might work better:

SELECT * from [MyNamedRange]

or

SELECT * from [Sheet1$A1:B10]

Hi,

Has anyone had any problems runnin the aspnet_regsql.exe tool with a SQL Server that is on a different server as your development PC?

When the tools ask me to enter the Server, I type in abc-def,1234. The 1234 is the name of the port. The when I click on the database drop down I get the following error:

Failed to query a list of database names from the SQL Server. Invalid object name 'sysdatabases'.

Why does it do this? I can open the database in SQL Server Eneterprise Manager for the 2000 database.

goto in sql server 2000 stoed procedure

in stored procedure sql server 2000 , i am using the goto keyword to send the user to execute the particular line , Is this the right way to do so ?
I am saying this because , in general , we are told to stop using the goto keyword , as far as the memory consumption is concerned.

Yesterday is a canceled check. Tomorrow is a promissory note. Today is the ready cash. USE IT.

I'm not sure why memory consumption should be an issue. The traditional arguments against using GOTO are outlined in this article[^]. What are you using GOTO for?

its better not to use goto statement. try to use some alternate to perform the functionality.

hi M.Nouri

What is the Error when you try to Connect?

i was gonna Say post your code so i see if there is something wrong, am not into Delphi and i don't know how the syntax looks like, am into .NET C# or Vb then it would be easy for me to help you. Why do you still use Delphi if i may ask, what is it there is there and that is not in .NET?

i have done some small googling and i found this hope it will help.
