--------------------------------------

             Summary: HPL/SQL requires single quotes for string literals, 
resulting in surprising behavior
                 Key: HIVE-17027
                 URL: https://issues.apache.org/jira/browse/HIVE-17027
             Project: Hive
          Issue Type: Bug
          Components: hpl/sql
            Reporter: Carter Shanklin
            Priority: Critical


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.
