I have created a simple new Rad Server Package with resource with a data module to access a Firebird 3.05 database running on Ubuntu 18.0.4. I included sample endpoints and a database endpoint with one table from the database.
I modified the created FDQuery to return a subset of the records.
select * from EXPENSES where COMPANYID = :COMPANYID
It indicated the FireDACFBDriver was not found, and instead of adding the PhysFBDriverLink, I deleted the FireDACFBDriver in the project source and it asked to add back the FireDACIBDriver and it works. This is besides the point, I think, but just full disclosure. I have tried the PhysFBLink with same results, but have had trouble switching back and forth to Linux deploy, so this works for testing I believe.
The client app consists of a TEMSFireDACClient, a FDSchemaAdapter, FD TAble Adapter, FDMemTable and datasource and dbgrid and three buttons.
Button1
Expenses.GetEndpoint.Params.Clear()
expenses.GetEndpoint.Params.AddItem(
'CompanyID','10000080');
Expenses.GetData();
Button2
FDMemTable1.delete;
Button3
Expenses.GetEndpoint.Params.Clear();
expenses.GetEndpoint.Params.AddItem(
'CompanyID','10000080');
Expenses.PostUpdates;
Button One retrieves multiple rows, and button two deletes a row locally, and button 3 tries to apply the table updates back to the server.
When attempting to post updates. I get the following error:
EMS Error: Resource error. Request parameter not found: COMPANYID.
This works when the resource SQL is SELECT * FROM EXPENSES. Is it just that the TEMSDataSetResources can only work on the full table, or Is there something simple I am missing or a reference available for how to accomplish this?
I have tried creating a manual delete endpoint with:
delete from EXPENSES where EXPENSEID = #####
However, that is another post maybe if I have to go there. I cannot get around and error converting Unicode to integer variant when passing the parameter.
