James F. Adams updated DERBY-183:
---------------------------------
Attachment: Derby183.patch4.txt
The lookahead in the grammar of my previous patches did not work for some
parameter types. I have reworked the lookahead to use syntactic lookahead
similar to that used elsewhere in the grammar. I have included an additional
test that would have failed with the previous patch. I have run the
lang/functions.sql and lang/procedure.java using the various frameworks without
error.

> A statement like
> create function s2.f2( char(8), integer) returns int
> language java parameter style java external name 'myclass.mymethod'
> fails with the message
> ERROR 42X01: Syntax error: Encountered "char" at line 1, column 24
> However
> create function s2.f2( p1 char(8), p2 integer) returns int
> language java parameter style java external name 'myclass.mymethod'
> is accepted.
> The Derby documentation (at
> http://incubator.apache.org/derby/manuals/reference/sqlj27.html#CREATE+PROCEDURE+Statement),
> the SQL2003 standard, and DB2 all agree that the parameter name is optional.
