[jira] Updated: (DERBY-183) Parameter names required in CREATE
FUNCTION
[ http://issues.apache.org/jira/browse/DERBY-183?page=all ]
James F. Adams updated DERBY-183:
---------------------------------
Attachment: Derby183.patch.txt
I have attached a patch that:
1) Modifies java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
a) Initializes parameterName to "" in procedureParameterDefinition and functionParameterDefinition
b) Makes parameterName optional in procedureParameterDefinition and functionParameterDefinition
2) Modifies java/engine/org/apache/derby/impl/sql/compile/CreateAliasNode.java to ignore function and procedure parameter names equal to "" when checking for duplicate parameter names.
I have run derbyall with no additional failures noted. I also ran dblook on a database which contained functions and procedures with parameters that had just parameter types specified. The resultant DML looked good.

> 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.
