Benchao Li commented on CALCITE-5551: ------------------------------------- [~hamnis] Before we are going into the implementation details, we'd better make the specification clear in the Jira first. E.g., * Is {{SELECT * EXCEPT()}} valid? * Is {{SELECT col1 as new_col, * EXCEPT(col2)}} valid? * Is {{SELECT * EXCEPT(col1), col2 as new_col}} valid? * How does it handle derived column names, such as {{SELECT * EXCEPT(???) FROM (SELECT 1, 2, 3)}}? You can come up with more cases. After we settle down the specification, then we'll go to the implementation. > Implement SELECT * EXCEPT field > ------------------------------- > > Key: CALCITE-5551 > URL: https://issues.apache.org/jira/browse/CALCITE-5551 > Project: Calcite > Issue Type: Improvement > Reporter: Erlend Hamnaberg > Priority: Major > Labels: pull-request-available > Time Spent: 0.5h > Remaining Estimate: 0h > > Some databases like bigquery support SELECT * Except (field1, field2) > > https://cloud.google.com/bigquery/docs/reference/standard-sql/query-syntax#select_except -- This message was sent by Atlassian Jira (v8.20.10#820010)
