Hi, Rock, To get ibis.cpp to print the RIDs, please use option '-output filename' with option '-rid'. This will output the selection results along with the RIDs.
For the results of joins, you will need to write them to disk and them use ibis.cpp. Alternatively, you might consider queries involve "AND NOT" (which is commonly refer to as logical minus). Good luck. John On 1/30/12 5:15 PM, Rock Wang wrote: > Hi John, > > With command ibis -y to yank rows, it accepts a file with a list of > row ids?
