Using Variable In DataReader's SqlCommand Text

Jan 17, 2007

I'm attempting to configure a DataReader's SqlCommand text to use a package-level variable and I'm having trouble. I've read about using the "sql command from variable" option but although I see that during the configuration of Ole DB source, I don't see the same option for DataReader source. Viewing the properties of the DataReader and selecting the SqlCommand property does have button to configure the value but only displays a string value editor window. (I was hoping for the expression editor.)

The configured connection to the DataReader uses the odbc Data Provider (under .Net providers). I'm connecting to mySql, if that matters.

What I'm looking to do is to use a variable in the where clause of the DataReader's SqlCommand. Any hints how to accomplish this or other ideas would be greatly appreciated.

Thanks

Problem With Variable In DataReader SQLCommand

Nov 20, 2007

Hello,
I'm trying to set the SQLCommand of a DataReader with a string variable (at the DataFlow Task level), and I'm having some problems. The source is a DB2 table. The destination is an MS Excel file. Here is what I have:

1. A variable named SQLStatementDataFlow of type String. EvaluateAsExpression is set to True, and the SQL statement in the expression evaluates without a problem.
2. In the Expression property of the DataFlow Task, I have the [SqlCommand] property configured with the variable.

First, in the component properties of the DataReader, what kind of SQLCommand do I set up here if the DataFlow SQLCommand is configured to use a variable?

Thank you for your help!

Can The Result From An EXEC(@sqlcommand) Be Returned To A Variable

Apr 11, 1999

Is it possible to get the result from an EXEC(@sqlcommand) statement into a variable?

As part of a SQL loop, it is necessary for me to run an EXEC() command to process an SQL statement. I have succesfully implemented this, but have been unable to get the results from the EXEC() statement into a variable to allow this data to be inserted into a table. Is this possible?

For Example (I know this doesn't work, but it is effectively what I am trying to achieve):

select @result = EXEC(@sqlcommand)

I could then use the @result variable in an insert statement to update a table with the results from the EXEC command.

Any assistance would be greatly appreciated...

Regards,
Wayne

If (Session("syozokubu_id") = 20) And (Session("syozokuka_id") = 21) And ((Session("kaikyuu_id") = 23)) Then
 p_s_syounin2 = ("INSERT INTO (p_s_syounin2) SELECT syain_hnm FROM TR_syainID WHERE TR_syainID.syozokubu_id=20 AND TR_syainID.syozokuka_id=21 AND TR_syainID.kaikyuu_id=23, cnn")   '''' THIS DOES NOT WORK!
End If
End Sub
 p_s_syounin2 .ExecuteNonQuery()
 
What is the correct way of declaring  p_s_syounin2?

SqlCommand Parameters.Add

Mar 12, 2008

Using SqlCommand, this is how I am updating a database table:


Sub UpdateDataGrid(obj As Object, ea As DataGridCommandEventArgs)    strSQL = "UPDATE Basket SET Quantity = Qty, Total = TotAmt WHERE BasketID = BID AND ProductID = PID"    sqlCmd = New SqlCommand(strSQL, sqlConn)    With sqlCmd        .Parameters.Add("Qty", SqlDbType.Int).Value = CInt(iQty)        .Parameters.Add("TotAmt", SqlDbType.Money).Value = CInt(iQty) * CType(ea.Item.FindControl("lblPrice"), Label).Text        .Parameters.Add("BID", SqlDbType.VarChar, 50).Value = strBasketID        .Parameters.Add("PID", SqlDbType.VarChar, 50).Value = CType(ea.Item.FindControl("lblID"), Label).Text    End With      sqlConn.Open()    sqlCmd.ExecuteNonQuery()    sqlConn.Close()End Sub


But the above code generates the following error pointing to the red colored line in the above code:
Invalid column name 'BID'.Invalid column name 'PID'.
BID & PID are not the column names in the actual database table but can't it be done in the way I have done above? In fact, Qty & TotAmt are not the column names in the actual database table as well; so why isn't the error pointing to Qty & TotAmt as they will be evaluated before BID & PID, if I am not mistaken?

SqlCommand.StatementCompleted Event - How To Use In ASP

Mar 24, 2008

Hi, I've come from desktop to web (say no more?)
I'd like to fire a sqlCommand.StatementCompleted event in ASP.NET & use the sender argument to retrieve the output of a stored proc.
The command is in a button event. The event handler += is also set up in the same button event. Naturally the event handler proc is separate as its own procedure
In the event handling procedure, I cast the sender arg. to an SQLCommand object & try to extract the value of the output parameter.
When I try to do this I get a "No reference set to object" error raised in . Is this because there was a post back after the command completed & the Command object lost its state? If so, what would be the best way to retain the parameters value? Using session state or Profile?
Any help would be greatly appreciated
below is cut down code as to what I'm doing:protected void Button1_Click(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand();
cmd.StatementCompleted += new StatementCompletedEventHandler(c_StatementCompleted); cn.Open(); cmd.ExecuteNonQuery(); cn.Close();
}
void c_StatementCompleted(object sender, StatementCompletedEventArgs e)
{
// get an error here
string result = ((SqlCommand)sender).Parameters["returnPrm"].Value.ToString();
}

Sql Error - In The SqlCommand.ExecuteNonQuery

Aug 12, 2004

Hi

I have an asp.net [c#] page that queries a database which worked fine until I entered a new field called VSReferenceNumber.

The error message suggest there is something wrong with the sql string, but for the life of me I can't see why it is wrong.

I believe the problem is somewhere here:

SqlString += "VSReferenceNumber = '" + VSReferenceNumber.Replace("'", "''") + "', ";


Any help would be most appreciated.

Many thanks in advance
