1. MyQuery.RecordCount tells you the
number of records returned
2. This can be dangerous if the query is large as
depending on the drivers you are using the only way for Delphi to find the
number of records is for it to scan the query from start to finish
3. Eof will not return true if you return one
record. the following code works in the situation where one record is
returned
MyQuery.Open;
While Not MyQuery.Eof do
begin
// do some processing here
MyQuery.Next;
end;
Eof will only be true when you open a query if 0 records are
returned.
Please note... these assumptions about EOF are based on the
databases and drivers that **I** have used.

Subject: [DUG]: TqueryHi,Is there any easy way to know how many records a select query has returned.The problem I have is I was doing a while on EOF but if only one record is returned the EOF is true and my while code does not execute.Thanks--------------------------------------------------------------------------------
