Parth Chandra updated DRILL-1836:
---------------------------------
Fix Version/s: (was: 1.0.0)
Future
> Default length for Varchar in cast expressions should be changed
> ----------------------------------------------------------------
>
> Key: DRILL-1836
> URL: https://issues.apache.org/jira/browse/DRILL-1836
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Data Types
> Reporter: Abhishek Girish
> Assignee: Mehant Baid
> Fix For: Future
>
>
> Current behavior:
> Specify length:
> > select cast(t1.colfam1.col1 as varchar(10)) from table1 t1;
> +------------+
> | EXPR$0 |
> +------------+
> | val1 |
> | val21 |
> | val26 |
> +------------+
> Default length for varchar in a cast expression:
> > select cast(t1.colfam1.col1 as varchar) from table1 t1;
> +------------+
> | EXPR$0 |
> +------------+
> | v |
> | v |
> | v |
> +------------+
> When the length attribute is not specified with varchar, in a cast
> expression, Drill treats the default length to be 1.
> Postgres and SQL Server sets the default length to be 30 in such a scenario.
> The behavior for Drill must be modified to something similar.
