Re: Deleting a record with ADO .... HELP
I find using the adodb.command easier than the adodb.recordset to delete
When tables are linked, delete the dependent records 1st.
For example you have 2 tables, one a customer table and one a invoice table.
database integrity forces you to delete the invoices related to a customer
before you can delete the customer.
Find the Unique Identifier for that customer and delete the invoices related
to that customer then delete the customer.
you may want to prompt the user before deleting the records like: "deleting
this customer will delete 5 invoices, do you wish to continue?"
ado command to delete a record:
Dim adodel As ADODB.Command
Set adodel = New ADODB.Command
.ActiveConnection = activeconnection
.CommandType = adCmdText
.CommandText = "Delete from table where uniqueid = " & idstr
.CommandTimeout = 30
Set adodel = nothing
