-----------------------------------

> Support non-constant expressions for array indexes.
> ---------------------------------------------------
>
> Key: HIVE-1955
> URL: https://issues.apache.org/jira/browse/HIVE-1955
> Project: Hive
> Issue Type: Improvement
> Reporter: Adam Kramer
> Assignee: Navis
> Fix For: 0.14.0
>
>
> FAILED: Error in semantic analysis: line 4:8 Non Constant Expressions for
> Array Indexes not Supported dut
> ...just wrote my own UDF to do this, and it is trivial. We should support
> this natively.
> Let foo have these rows:
> arr i
> [1,2,3] 1
> [3,4,5] 2
> [5,4,3] 2
> [0,0,1] 0
> Then,
> SELECT arr[i] FROM foo
> should return:
> 2
> 5
> 3
> 1
> Similarly, for the same table,
> SELECT 3 IN arr FROM foo
> should return:
> true
> true
> true
> false
> ...these use cases are needless limitations of functionality. We shouldn't
> need UDFs to accomplish these goals.
