@marmbrus I met a problem when I write the test case:
```
createQueryTest("test ambiguousReferences resolved as hive",
"""
|CREATE TABLE t1 (x int);
|CREATE TABLE t2 (a STRUCT<x:string>, x int);
|INSERT OVERWRITE TABLE t1 SELECT 1 FROM src LIMIT 1;
|INSERT OVERWRITE TABLE t2 SELECT named_struct("x","str"),1 FROM src
LIMIT 1;
|SELECT a.x FROM t1 a JOIN t2 b ON a.x = b.k;
""".stripMargin)
```
Then I found spark-sql not support `SELECT named_struct`
Do you have any other way to insert data to table `t2` in spark-sql?
