Description

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.

Example from the docs is as follows:
CREATE TABLE dept (
deptno NUMBER(2,0),
dname NUMBER(14),
loc VARCHAR2(13),
CONSTRAINT pk_dept PRIMARY KEY (deptno)
);

With this config:
<configuration>
<property>
<name>hplsql.conn.default</name>
<value>hiveconn</value>
</property>

<property>
<name>hplsql.conn.hiveconn</name>
<value>org.apache.hive.jdbc.HiveDriver;jdbc:hive2://</value>
</property>
</configuration>

I get this error:
Caused by: java.lang.RuntimeException: org.apache.hadoop.hive.ql.parse.ParseException:line 2:9 cannot recognize input near 'NUMBER' '(' '2' in column type
With this config:
<configuration>
<property>
<name>hplsql.conn.default</name>
<value>hiveconn</value>
</property>

<property>
<name>hplsql.conn.hiveconn</name>
<value>org.apache.hive.jdbc.HiveDriver;jdbc:hive2://</value>
</property>

<property>
<name>hplsql.conn.convert.hiveconn</name>
<value>true</value>
</property>
</configuration>

the example works.
