title: Temporary table resource limit
body: <p>i have two applications (server and client), that uses TQuery connected with TClientDataSet through TDCOMConnection,
  and in some cases clientdataset opens about 300000 records and than application throws exception "Temporary table resource limit".</p>
  
  <p>Is there any workaround how to fix this? (except "do not open such huge dataset"?)</p>
  
  <p>update: oops i'm sorry there is 300K records, not 3 millions..</p>
