The query is:
```scala
createQueryTest("constant object inspector for generic udf",
"""SELECT named_struct(
lower("AA"), "10",
repeat(lower("AA"), 3), "11",
lower(repeat("AA", 3)), "12",
printf("Bb%d", 12), "13",
repeat(printf("s%d", 14), 2), "14") FROM src LIMIT 1""")
```
Since `printf` in Hive didn't change word case in `Bb%d`, therefore, `Bb12`
is the right answer
