Rick Hillegas updated DERBY-4066:
---------------------------------
Attachment: derby-4066-02-ac-outputLOBs.diff
Attaching derby-4066-02-ac-outputLOBs.diff. This patch allows LOB-valued
OUT/INOUT arguments to Derby routines. Regression tests passed cleanly for me.
As follow-on work, we will want to verify that large LOBs behave correctly.
Hopefully, the work on DERBY-4544 will be applicable to DERBY-4754 and help
improve the performance of LOB arguments.
Touches the following files:
--------------
M java/engine/org/apache/derby/impl/sql/compile/CreateAliasNode.java
Allow LOB types as OUT and INOUT arguments in routine declarations.
--------------
M java/engine/org/apache/derby/impl/jdbc/EmbedCallableStatement.java
Retrieve LOB values from OUT and INOUT parameters of CallableStatements.
--------------
M java/client/org/apache/derby/client/net/NetCursor.java
M java/drda/org/apache/derby/impl/drda/EXTDTAInputStream.java
M java/drda/org/apache/derby/impl/drda/DRDAResultSet.java
M java/drda/org/apache/derby/impl/drda/DRDAConnThread.java
Transport LOB-valued OUT/INOUT parameters across the network.
--------------
M
java/testing/org/apache/derbyTesting/functionTests/tests/jdbcapi/ParameterMappingTest.java
Verify small LOB-valued OUT/INOUT 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.
