Return the underlying source of the Server
PROPERTY Source AS USUAL
- String
- AdoCommand Object
- AdoStream Object
When a new source is assigned, the server will send a NOTIFYINTENTTOMOVE before the operation and a NOTIFYFILECHANGE after the operation.
Assigning a new source changes the underlying source of a recordset. Please make sure that you return the same column layout as the original source, or else clients (datawindows, browser) using the server may get confused.
Setting the source will perform the following changes:
•The original recordset will be closed
•The recordset will be reopened using the new source
•The new column layout will be read
•The server will be positioned on the first row of the new result set
•a Notify(NOTIFYFILECHANGE) will be send to the clients of the server
If the new source is invalid the recordset will remain closed and the server becomes 'useless'
oSrv := AdoServer{"Select * from Employee order by emp_id", oConn,AdOpenStatic}
? "Original Source", oSrv:Source
// Do something
// Change source using String
oSrv:Source := "Select * from Employee where emp_id like 'P%' order by emp_id"
? "New Source", oSrv:Source
// Do something else
