Question : SQL select query syntax, attempting to pass a integer variable from vb.net to a sql string select command

Hello,

I'm attempting to use the same function with different integer values for a weekly or monthly view rather than writing two functions if possible.

VB.Net connection method:

Private dcMRP As Odbc.OdbcConnection = New Odbc.OdbcConnection("DSN=abc;uid=xyz;pwd=123")

Here's the end of my sql string statement

sql = and material_Req.Due_Date between GetDate()-1 and getdate()+6 and material_req.Material =" & "'" & cboMaterialID.SelectedValue & "'"

Dim cmd As New Odbc.OdbcCommand(sql, dcMRP)
            dcMRP.Open()

            MatlReqs1 = cmd.ExecuteScalar


The above statement works fine, this basically gives a week 1 data.

What I'm attempting to do is use a variable instead of the 1 and the 6 and be able to switch to a monthly view and use the same function to return monthly data when needed.



Weekly view attempt:

Private Bucket1Start As Integer = 1
Private Bucket1End As Integer = 6

sql = and material_Req.Due_Date between GetDate()-Bucket1Start and getdate()+Bucket1End and material_req.Material =" & "'" & cboMaterialID.SelectedValue & "'"


monthly view attempt:

Private Bucket1Start As Integer = 1
Private Bucket1End As Integer = 30

sql = and material_Req.Due_Date between GetDate()-Bucket1Start and getdate()+Bucket1End and material_req.Material =" & "'" & cboMaterialID.SelectedValue & "'"


ERROR[42522][ODBC][ODBC SQL Server Driver][SQL Server]Invalid column name 'Bucket1Start
ERROR[42522][ODBC][ODBC SQL Server Driver][SQL Server]Invalid column name 'Bucket1End



Thanks,
Jon

Answer : SQL select query syntax, attempting to pass a integer variable from vb.net to a sql string select command

Something like this:

sql = "and material_Req.Due_Date between GetDate()- " & Bucket1Start & " and getdate()+ " & Bucket1End & " and material_req.Material =" & "'" & cboMaterialID.SelectedValue & "'"
