i want to know how i can pass multiple values in the form of arrays to a stored procedures.
the technique by which i pass multiple values to a stored procedure beginning along with declarations are as follows:
Dim configurationAppSettings As System.Configuration.AppSettingsReader = New System.Configuration.AppSettingsReader()
Me.cmdInsSlabHmst = New System.Data.OleDb.OleDbCommand()
Me.OleDbConnection1 = New System.Data.OleDb.OleDbConnection()
Me.cmdInsSlabDMst = New System.Data.OleDb.OleDbCommand()
'
'cmdInsSlabHmst
'
Me.cmdInsSlabHmst.CommandText = "PKGSLABHMST.INSSLABHMST"
Me.cmdInsSlabHmst.CommandType = System.Data.CommandType.StoredProcedure
Me.cmdInsSlabHmst.Connection = Me.OleDbConnection1
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iSLABDESC", System.Data.OleDb.OleDbType.VarChar, 50))
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iSLABUNIT", System.Data.OleDb.OleDbType.VarChar, 1))
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iREMARKS", System.Data.OleDb.OleDbType.VarChar))
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iSLABFROM", System.Data.OleDb.OleDbType.VarChar))
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iSLABRATE", System.Data.OleDb.OleDbType.VarChar))
Me.cmdInsSlabHmst.Parameters.Add(New System.Data.OleDb.OleDbParameter("iNOOFRECORDS", System.Data.OleDb.OleDbType.Integer))
'
'OleDbConnection1
'
Me.OleDbConnection1.ConnectionString = CType(configurationAppSettings.GetValue("ConnectionString", GetType(System.String)), String)'Passing multiple values to the procedure with the help of ~ sign
Dim strCode As String
Dim i As Integer
'Dim dblSlabRate As Decimal
'Dim dblSlabFrom As Decimal
Dim strSlabRate As String
Dim strSlabFrom As String
Dim strSlabRateP As String
Dim strSlabFromP As String
Dim intCntr As Integer
'Me.cmdInsSlabHmst.Parameters("iSLABDESC").Value = txtSlabDesc.Text
'Me.cmdInsSlabHmst.Parameters("iSLABUNIT").Value = ddlSalbUnit.SelectedItem.Value
'Me.cmdInsSlabHmst.Parameters("iREMARKS").Value = txtRemarks.Text
'OleDbConnection1.Open()
'strCode = cmdInsSlabHmst.ExecuteScalar
'OleDbConnection1.Close()
For i = 0 To dgSlabDtl.Items.Count - 1
If i = dgSlabDtl.Items.Count - 1 Then
'dblSlabRate = CType(dgSlabDtl.Items(i).FindControl("txtSlabRate"), TextBox).Text
'dblSlabFrom = CType(dgSlabDtl.Items(i).FindControl("txtSlabFrom"), TextBox).Text
strSlabRate = CType(dgSlabDtl.Items(i).FindControl("txtSlabRate"), TextBox).Text
strSlabFrom = CType(dgSlabDtl.Items(i).FindControl("txtSlabFrom"), TextBox).Text
Else
'dblSlabRate = CType(dgSlabDtl.Items(i).FindControl("lblSlabRate"), Label).Text
'dblSlabFrom = CType(dgSlabDtl.Items(i).FindControl("lblSlabFrom"), Label).Text
strSlabRate = CType(dgSlabDtl.Items(i).FindControl("lblSlabRate"), Label).Text
strSlabFrom = CType(dgSlabDtl.Items(i).FindControl("lblSlabFrom"), Label).Text
End If
strSlabRateP += strSlabRate & "~"
strSlabFromP += strSlabFrom & "~"
intCntr += 1
'If dblSlabRate <> "" And dblSlabFrom <> "" Then
'InsDtl(strCode, dblSlabFrom, dblSlabRate)
'End If
Next
If strSlabRateP <> "" And strSlabFrom <> "" Then
With cmdInsSlabHmst
.Parameters("iSLABDESC").Value = UCase(txtSlabDesc.Text)
.Parameters("iSLABUNIT").Value = ddlSalbUnit.SelectedItem.Value
.Parameters("iREMARKS").Value = txtRemarks.Text
.Parameters("iSLABFROM").Value = strSlabFromP
.Parameters("iSLABRATE").Value = strSlabRateP
.Parameters("iNOOFRECORDS").Value = intCntr
End With
OleDbConnection1.Open()
cmdInsSlabHmst.ExecuteNonQuery()
OleDbConnection1.Close()
End If
to the insert procedure i am passing multiple values with the help of ~ sign and in the procedure the individual values are separated by identifying the position of ~ sign and the no. of records which have been passed. For which a complicated stored procedure has been written.
i want to pass multiple values in an array, so that my stored procedure becomes simple and runs faster. So, if someone tells me how to pass arrays to a stored procedure (with code example), it will be of real help.

subhajitWell, what you are doing is probably the way to go. I don't understand though, how you can say a 'complicated stored procedure' was written to chop up a ~ delimited list. It should be only a couple of very simple statements to do.
I do the same thing quite often, for example if I have a checkboxlist and I want to pass a list of all items that the user checked to a stored proc, I go through the list in my ASP code and create a string in much the same way you do. Then in my stored proc I do something like:
while strpos(@.List, '~') > 0
begin
insert into #Table values (substring(@.List, 1, strpos(@.List, '~') - 1))
set @.List = substring(@.List, strpos(@.List, '~') + 1, length(@.List))
end
which is easy enough for me, and executes in a flash, even for hundreds of items.
If you reach the limit of this code (@.List close to 8000 chars) you need to do something else. In this case it can be useful to consider your specific application. Where are those values coming from? Are you storing it in bits and pieces to the array, and then in one shot you want to write it to your DB? If so you should think about writing the values to your DB as they become available - instead of keeping them in an array in server memory.
But from your code it looks like you're just doing the same sort of thing I do, so I don't see the problem.
BTW, your code is very difficult to look at, since 1/2 of it is commented out. If you can distill it into just what we need to see your problem, it makes it easier for us to help you. It will also increase the likelyhood of an accurate answer.sql
