Juhwan Kim created CALCITE-3884: ----------------------------------- Summary: Return type for SIGN function is incorrect Key: CALCITE-3884 URL: https://issues.apache.org/jira/browse/CALCITE-3884 Project: Calcite Issue Type: Bug Components: core Reporter: Juhwan Kim
It appears the metadata for the SIGN function in Calcite is incorrect, it uses the input metadata as the output metadata. [ SqlStdOperatorTable.java#L1713 | https://github.com/apache/calcite/blob/1c261ebeb65e775b908cb878e905410ce78cda80/core/src/main/java/org/apache/calcite/sql/fun/SqlStdOperatorTable.java#L1713] This works in most cases but for Decimal where prec=scale, this doesn’t work since there can be no whole digits. The return metadata should really be an int, or if you want to match types then DECIMAL(1, 0) if the input metadata is any DECIMAL. -- This message was sent by Atlassian Jira (v8.3.4#803005)
