这个家伙糟厉害 函数 这样写!有谁见过这样写的吗?

function GetPartFilter(AID: string): string; //单元头部分还定义了
var
querytemp: TOceanQuery;
s: string;
lOwnerids: TStringList;
procedure GetOwnerids(AID: string); //压根 都不用定义 都可以???
var lQuery: TOceanQuery;
begin
lQuery := TOceanQuery.Create(nil);
try
lQuery.Close;
lQuery.SQL.Text := 'select ID from PartInfo where Ownerid=' + QuotedStr(AID) + ' and ID<>' + QuotedStr(AID) + ' and ImageIndex=0';
lQuery.Open;
while not lQuery.Eof do
begin
lOwnerids.Add(lQuery.FieldByName('ID').AsString);
GetOwnerids(lQuery.FieldByName('ID').AsString);
lQuery.Next;
end;
finally
lQuery.Free;
end;
end;
var I: Integer;
begin
Result := '';
querytemp := TOceanQuery.Create(nil);
lOwnerids := TStringList.Create;
try
querytemp.Close;
querytemp.SQL.Text := 'select ID,ImageIndex from partinfo where ID=''' + AID + '''';
querytemp.Open;
if querytemp.IsEmpty then Exit;
if querytemp.FieldByName('ImageIndex').AsInteger <> 0 then
begin
Result := 'ID=' + QuotedStr(AID);
Exit;
end;
lOwnerids.Add(querytemp.FieldByName('ID').AsString);
GetOwnerids(querytemp.FieldByName('ID').AsString);
for I := 0 to lOwnerids.Count - 1 do
begin
if Result = '' then
Result := 'Ownerid in (' + QuotedStr(lOwnerids[I])
else
Result := Result + ',' + QuotedStr(lOwnerids[I]);
end;
if Result <> '' then
Result := Result + ')';
finally
querytemp.Free;
lOwnerids.Free;
end;
end;
