Subject [jira] Updated: (DERBY-4703) Make it possible for table functions to return BOOLEAN columns
Date Fri, 18 Jun 2010 00:05:23 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4703?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rick Hillegas updated DERBY-4703:
---------------------------------

    Attachment: derby-4703-01-aa-booleanTableFunctionColumns.diff

Attaching derby-4703-01-aa-booleanTableFunctionColumns.diff. This allows table functions to
have BOOLEAN columns. The regression tests passed for me.

Touches the following files:

---------------

M      java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj

Allow BOOLEAN columns in table functions.

---------------

M      java/engine/org/apache/derby/iapi/types/TypeId.java
M      java/engine/org/apache/derby/catalog/types/TypeDescriptorImpl.java

Adjust type information so that DatabaseMetaData.getFunctionColumns() returns information
compatible with ResultSetMetaData.

---------------

M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/TableFunctionTest.java

Regression test.
