WebServices and variables

[hsteigstra]

I am making the first steps in WebServices and have created my first server using a TOracleDataset as source, simply displaying a small list of languages. As soon as I extend the query with a variable and try to set it, I get either the error "Not all variables bound" or "Variable :LNG_ID not declared", although I have defined the variable properly. I am setting the value in the BeforeGetRecords or BeforeGetParams event of the TDatasetProvider component.
Is this a bug or am I doing something wrong? I have D6.02 and DOA 3.4.6.4

The Params in a TClientDataSet will define the variables of the TOracleDataSet. Instead of defining TOracleDataSet variables you can define the TClientDataSet Params.

Alternatively you can do a Fetch Params before opening the TClientDataSet.

I am not quite folowing you. From the Delphi documentation I learn that I have to pass the variables through the OwnerData variable in the BeforeGetRecords event. There I get the error.
The parameters set in the ClientDataSet in the client application are not passed through and the "Fetch params" does not fill in the parameters.
Any further suggestions?
