Rick Hillegas updated DERBY-4066:
---------------------------------

    Attachment: derby-4066-01-aa-enableLobArgs.diff

Attaching derby-4066-01-aa-enableLobArgs.diff. This patch removes disabling code which prevents us from declaring and invoking functions/procedures with LOB arguments.

I haven't run regression tests yet and I'm waiting for community feedback on why we don't allow these arguments today.

Touches the following files:

M      java/engine/org/apache/derby/impl/sql/compile/CreateAliasNode.java

Removes the code which prevents us from declaring functions/procedures with long argument types.


M      java/engine/org/apache/derby/impl/sql/compile/MethodCallNode.java

Removes the code which prevents us from invoking functions/procedures with long argument types.


M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/AnsiSignaturesTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/AnsiSignatures.java

Adds some simple tests to verify that you can now declare and invoke functions with LOB arguments.

> Derby objects if you try to declare a function or procedure with an argument whose type is BLOB or CLOB. These kinds of arguments are allowed in the SQL standard and the matching Java types are java.sql.Blob and java.sql.Clob. See the SignatureMatching.html summary attached to DERBY-3652.
> We should lift this restriction and allow functions and procedures to take large object arguments.
