Timo Walther created FLINK-8953: ----------------------------------- Summary: Resolve unresolved field references in FieldComputer expressions Key: FLINK-8953 URL: https://issues.apache.org/jira/browse/FLINK-8953 Project: Flink Issue Type: Improvement Components: Table API & SQL Reporter: Timo Walther
When implementing the {{FieldComputer.getExpression}} method, it is not possible to use API classes but only internal expression case classes. It would be great to also define timestamp extractors like: {code} def getExpression(fieldAccesses: Array[ResolvedFieldReference]): Expression = { // 'x.cast(Types.LONG) // ExpressionParser.parseExpression("x.cast(LONG)") } {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
