James Taylor commented on PHOENIX-2886:
---------------------------------------
Yes, exactly, [~sergey.soldatov], thanks. That's a much better way of saying
it. That's similar to what CaseExpression.coerceIfNecessary() does. But the
isCoercible doesn't take into account scale and max length, so you'd need to
track that and keep the largest one as you loop through the types.
> Union ALL with Char column not present in the table in Query 1 but in Query
> 2 throw exception

> To reproduce:
> create table person ( id bigint not null primary key, firstname char(10),
> lastname varchar(10) );
> upsert into person values( 1, 'john', 'doe');
> upsert into person values( 2, 'jane', 'doe');

> person;

> data. Expected length of at least 106 bytes, but had 13
