Passing values to an SQL Server backend database using a form

G

Guest

Hi,

I am trying to pass values from a form to an SQL Server 2000 DB using the
OpenRecordSet method and then the .AddNew function. Originally my code was
working intermittently, but I kept getting errors saying I need to add
dbSeeChanges to my OpenRecordSet method.

I added dbSeeChanges to my code in the relevant places and now no data at
all is being passed to my SQL DB and I am getting errors complaining about
blank records.

Perhaps someone can look at my code and suggest where I am going wrong or
suggest an easier way to pass values directly from a form into SQL Server
2000.

Here's the code (sorry it's quite long):

Private Sub BtnImportDB_Click()

On Error GoTo Error_Handler

Dim db As Database
Dim recA As DAO.Recordset
Dim recB As DAO.Recordset
Dim recC As DAO.Recordset
Dim KeyA As Integer
Dim KeyB As Integer
Dim IntCounter As Integer 'Used to monitor which tables are updated

Set db = CurrentDb
IntCounter = 0

Set recA = db.OpenRecordset("dbo_AgentDetails", dbOpenDynaset, dbSeeChanges)
With recA
.FindFirst "AgentName = '" & Me!TxtAgntNme & "'" 'Check to see if the
agent details already exist

If .NoMatch Then 'Details don't exist in the SQL db. Update records

.AddNew
!AgentName = Me!TxtAgntNme
!AgentAddress1 = Me!TxtAgntAd1
!AgentAddress2 = Me!TxtAgntAd2
!AgentAddress3 = Me!TxtAgntAd3
!AgentAddress4 = Me!TxtAgntAd4

.Update

Else

updated", vbInformation, "Information Conflict"
IntCounter = 1
'Inform user records no updated
End If

End With

'requery the recordset to update the values
'recA.Requery
'recA.Close
'Set recA = Nothing

'sets the foreign key value for the Property table
KeyA = DLookup("[AgentKey]", "QrySelectAgent", "[AgentName] =

Are you using A project database or Access data database with odbc?

Why not using ADO?

simple Insert Example
dim lID as long
dim rs as adodb.recordset
dim cmdGetID as new adodb.command
dim cmdInsert as new adodb.command

cmdGetID.commandtext="SELECT ID FROM MyTable WHERE Name=?"
cmdGetID.Connection=CurrentProject.ActiveConnection
cmdGetID.Parameters.Refresh

cmdInsert.commandtext="INSERT INTO MyTable (Name) VALUES (?)"
cmdInsert.Connection=CurrentProject.ActiveConnection
cmdInsert.Parameters.Refresh

' best to put this in seperate function since you will call it more then
once :)
lID=0
cmdGetId.Parameters(0)=Value
set rs = cmdGetID.execute
if not rs.eof then
lID=rs(0)
end if
rs.close
if lID=0 then
cmdInsert.Parameters(0)=Value
cmdInsert.Execute
cmdGetId.Parameters(0)=Value
set rs = cmdGetID.execute
if not rs.eof then
lID=rs(0)
end if
rs.close
end if
set rs=nothing
set cmdGetId=nothing
set cmdInsert=nothing

You can even get better results when using Stored Procedures

spMyTable_Insert
(
@Value VARCHAR(100),
@ID INT=0 OUTPUT
)
AS
SET @ID=0
SELECT @ID=ID FROM MyTable WHERE Name=@Value
IF @ID=0
BEGIN
INSERT INTO MyTable (Name) VALUES (@Value)
SET @ID=@@IDENTITY
END



now vba code

dim cmdInsert as new adodb.command

cmdInsert.commandtext="spMyTable_Insert"
cmdInsert.CommandType=adCmdStoredProc
cmdInsert.Connection=CurrentProject.ActiveConnection
cmdInsert.Parameters.Refresh


cmdInsert.Parameters("@Value")=Value
cmdInsert.Execute
debug.print cmdInsert.Parameters("@ID") ' holds the new ID
