[jira] [Commented] (CALCITE-5624) Cannot parse array function for Spark Dialect

["Julian Hyde (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CALCITE-5624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17707454#comment-17707454 ] 

Julian Hyde commented on CALCITE-5624:
--------------------------------------

Before we dive into PRs, can we get to a precise description of the problem? First of all, the parser doesn't have a 'dialect' concept. It has conformance, lexical properties, and a function table (library). Which of those properties are you intending to use?

Second, it is a goal that every valid Spark query is valid in our parser, but it is not a goal that every invalid Spark query is invalid. In other words, you do not necessarily have to remove capabilities from the parser. (Unless leaving them in would create ambiguities.)
