> COALESCE Function - type of second parameter
> --------------------------------------------
>
> Key: PHOENIX-1237
> URL: https://issues.apache.org/jira/browse/PHOENIX-1237
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.0.0, 3.1, 4.1
> Reporter: Vaclav Loffelmann
> Assignee: Vaclav Loffelmann
> Attachments: PHOENIX-1237.fix.patch, PHOENIX_1237.patch

>
> There is an issue with automatic set data type of second parameter to
> coalesce function.
> For instance table:
> {code:sql}
> CREATE TABLE IF NOT EXISTS TEST_COALESCE(
> ID BIGINT NOT NULL,
> COUNT UNSIGNED_INT
> CONSTRAINT pk PRIMARY KEY(ID));
> {code}
> and query:
> {code:sql}
> SELECT COALESCE(SUM(COUNT), 0) FROM TEST_SUM GROUP BY ID;
> {code}
> This will cause in:
> {quote}SQLException: ERROR 507 (42846): Cannot convert type. COALESCE
> expected UNSIGNED_INT, but got INTEGER {quote}
> Hence second parameter is typed to its input value (eg. 0 is signed int not
> long), and long is expected. That is cause for ArrayIndexOutOfBoundsException
> described in PHOENIX-1229.
