[jira] [Created] (CALCITE-5288) Expression '(a > 1 and a < 3) or (a > 2 and a < 4)' cannot be simplified to 'SEARCH(a, Sarg[(1..4)])'
Aleksey Plekhanov created CALCITE-5288:
------------------------------------------
Summary: Expression '(a > 1 and a < 3) or (a > 2 and a < 4)' cannot be simplified to 'SEARCH(a, Sarg[(1..4)])'
Key: CALCITE-5288
URL: https://issues.apache.org/jira/browse/CALCITE-5288
Project: Calcite
Issue Type: Bug
Reporter: Aleksey Plekhanov
If there is only one range in search/sarg after simplification, the result of sarg collector is ignored (\{{SargCollector#needToFix()}} method).
Expression {{(a > 1 and a < 3) or (a > 2 and a < 4)}} is simplified to {{OR(SEARCH(a, Sarg[(1..3)]), SEARCH(a, Sarg[(2..4)]))}} but expected {{{}SEARCH(a, Sarg[(1..4)]){}}}.
If there are more the one intervals or if open interval exists, expressions simplified as expected.
