Rick Hillegas updated DERBY-4657:
---------------------------------
Attachment: derby-4657-01-aa-booleanReturnValues.diff
Attaching derby-4657-01-aa-booleanReturnValues.diff. This allows functions to
return BOOLEAN return values. Regression tests passed cleanly for me.
Touches the following files:
----------
M java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
Allows functions to be declared with BOOLEAN return values. BOOLEAN is still
not allowed as an argument or column type or as the target type in an explicit
CAST.
----------
M java/engine/org/apache/derby/impl/sql/compile/MethodCallNode.java
BOOLEAN is added to the list of JDBC types which have both primitive and
wrapper Java correspondences.
----------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/AnsiSignaturesTest.java
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/AnsiSignatures.java
Some unit tests verifying the correct resolution of BOOLEAN valued functions.
