Joe McDonnell reassigned IMPALA-966:
------------------------------------
Assignee: (was: Yongjun Zhang)
> Type errors are attributed to wrong expression with insert
> ----------------------------------------------------------
>
> Key: IMPALA-966
> URL: https://issues.apache.org/jira/browse/IMPALA-966
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 1.3
> Reporter: Henry Robinson
> Priority: Minor
>
> The type error below belongs to the second row to be inserted ({{sqrt()}}
> returns {{DOUBLE}}). But the obviously {{FLOAT}} first expression gets blamed
> for the error.
> {code}
> [localhost:21000] > insert overwrite alltypesnopart_insert(float_col)
> values(CAST(1.0 AS FLOAT)), (sqrt(-1));
> Query: insert overwrite alltypesnopart_insert(float_col) values(CAST(1.0 AS
> FLOAT)), (sqrt(-1))
> ERROR: AnalysisException: Possible loss of precision for target table
> 'functional.alltypesnopart_insert'.
> Expression 'cast(1.0 as float)' (type: DOUBLE) would need to be cast to FLOAT
> for column 'float_col'
> {code}
