Hi,
I use this ANTLR grammar file to parse Oracle PL/SQL statements:
http://pastebin.com/uy0wZTax
But some of the statements produce errors when I try to parse them, for example:
"create user u1 identified by p1 account unlock;"
I get the following error message:
==============================
statementString(1) : error 3 : , at offset -1
near [Index: 0 (Start: 141054912-Stop: 141054917) ='create', type<50> Line:
1 LinePos:-1]
: cannot match to any predicted input...
==============================
But why? The rule looks like this:
==============================
create_user_statement
: 'CREATE' 'USER' identifier 'INDENTIFIED' .*
;
==============================
Could the wildcard character be the problem?
Actually I just want to parse known Statements with my grammar, all unknown
statements (parsing errors) could be ignored.
Can I tell ANTLR (for the C target) to ignore those error messages and just
return FALSE or something like that, so that I can decide wether to take an
appropiate action?
I get a lot of those error messages, and to be honest, the error messages are
not helping me here. I can not see problems with the grammar.
Unfortunately I'm not able to debug the grammar with ANTLRworks.
Can someone show me the error or tell me a way to disable those error messages
in the ANTLR C target?
Andi
