----------------------------------------------------------
[~ashutoshc]
Reason for the following:
{code}
In addition to that error message has changed for -ve test cases of
=nonkey_groupby.q,subquery_shared_alias.q,clustern3.q,clustern4.q,udtf_not_supported1.q,selectDistinctStarNeg_2.q
We are losing line number and char position in error message.
{code}
Its because of the below line :
{code}
nonReserved -> Identifier[$nonReserved.text]
{code}
The above line generates the following code via ANTLR.
{code}
// 617:19: -> Identifier[$nonReserved.text]
{
adaptor.addChild(root_0,
(CommonTree)adaptor.create(Identifier,
(nonReserved277!=null?input.toString(nonReserved277.start,nonReserved277.stop):null))
);
}
{code}
The problem here is that it creates a new Identifier object at the expense of
losing the nonReserved277 token information such as start /end index, line
number, etc.
The fix would be to change the line to below:
{code}
nonReserved -> Identifier[$nonReserved.start]
{code}
This would prevent losing any valuable token information when the keyword input
is transformed to an identifier token.
