Description
You can reproduce the bug by running following test case from UdtTest.java:
@Test public void testUdt2() { final String sql = "select CAST(null AS \"adhoc\".mytype2) as ld " + "from (VALUES ROW(1, 'SameName')) AS \"t\" (\"id\", \"desc\")"; withUdt().query(sql).returns("LD=null\n"); }
Error thrown:
java.sql.SQLException: Error while executing SQL "select CAST(null AS "adhoc".mytype2) as ld from (VALUES ROW(1, 'SameName')) AS "t" ("id", "desc")": null at
