database - Loop/Iterate through a SQL query in Access (without VBA) -

-

i have rather unique problem sits between solution sets i've been able find. have database containing tables need iterative select queries updating input parameters. example, have equipment table contains pairing of technology sister tech, , mechanisms through communicate:

table fields:

  • techid1
  • techid1port
  • techid2
  • techid2port

example: radio communicates (through low/high band antenna) basestation (through antenna port)

i have working sql code runs when users select techid1 combobox , combobox value filters statement. however, need add levels of interaction based on added combobox (values:1-n). end goal iterate query done here, without vba, solution needs replicated many access tables , seamlessly transferred oracle/sql server in medium-term.

example of desired nth level results based on radio selection: list of techs directly interact radio (plus associated info), appended list of techs interact basestation , other 1st level results (no duplicates or trackbacks radio), etc nth level.

for above work without vba, realize there series of similar/identical queries need run, ability analyze row entries interaction level below current run. 1 simple potential solution i've looked @ nested subforms allow users expand higher interactions wish, can't find way subform , filter table onto itself.

big in advance! j

have tried use temporary tables. able filter different (sub)query's
