> This bug is part of a series of issues and surprising behavior I encountered writing a reporting script that would aggregate values and give rows different classifications based on an the aggregate. Addressing some or all of these issues would make HPL/SQL more accessible to newcomers.
> Consider this script:
> {code}
> CREATE FUNCTION test1()
> RETURNS STRING
> DECLARE
> VAR ret string;
> BEGIN
> ret := 'VALUE IS SET';
> print(ret);
> END;
> CREATE FUNCTION test2()
> RETURNS STRING
> DECLARE
> VAR ret string;
> BEGIN
> ret := "VALUE IS SET";
> print(ret);
> END;
> test1();
> test2();
> {code}
> The output of this script is:
> VALUE IS SET
> ret
> Hive accepts both quoting styles. It would be better if HPL/SQL did as well, or threw an error for th
> e unsupported style.
