-----------------------------------------
Description:
The sql conversion expects the child to be a sqlIdentifier. But a sqlBasicCall
is returned.
Script
{code:java}
A = LOAD 'scott.DEPT' as (DEPTNO:int, DNAME:chararray, LOC:CHARARRAY);
B = FOREACH A GENERATE FLATTEN(STRSPLIT(DNAME, ',')) as NAMES;
{code}
{code:java}
java.lang.ClassCastException: org.apache.calcite.sql.SqlBasicCall cannot be
cast to org.apache.calcite.sql.SqlIdentifier
