 Question and Answer Database
FAQ331D.txt Error: 'Missing Data Provider or Data Packet'
Category :DCOM/MultiTier/ActiveForm
Platform :All
Product :Delphi 3.x
Question:
Why does the error "Missing Data Provider or Data Packet"
occur?
Answer:
The error occurs when the ClientDataSet can't resolve to a
Provider reference on the application server or if the
Provider doesn't return records. Check that the
TClientDataSet ProviderName is filled in.
Background info: The error message originates in
DBConsts.pas as a constant SNoDataProvider which in turn
shows up in DBClient.pas (the unit that supports
TClientDataSet). The error is triggered in two situations:
1) When the TClientDataSet.Provider can't obtain a reference
to a provider through the RemoteServer component.
2) When the Provider doesn't return records to the
TClientDataSet (during TClientDataSet.OpenCursor).
