ClientDataSets : "Parameter not set in query string"

[StevenK]

I'm developing a Delphi 5 application and am making use of queries and clientdatasets with a SQL Server database back-end. When I link two queries (and their respective clientdatasets) I am given the error message "Parameter not set in query string." when I attempt to open the detail clientdataset (linked to a header clientdataset).
Can anyone suggest what I might be dooing wrong ?
Thanks in advance.
Steve.

I guess the queries you used have parameter set but you donot provide any parameter value in clientdataset. So you need to add parameter value in ClientDataSet.

please see TClientDataSet.Params online help for details.

Is there something similar to TClientDataSet.Params for Delphi 1.0?? I can't seem to find this for Delphi 1 (which I am using)

I think it's like zallen is writing.

Can it be something about the SQL-query itself?
If you have done something like this in the query :Something
you have done a parameter, and then you'll have to add a parameter string, or rewrite the query.
