Subject [jira] Commented: (DERBY-2260) DatabaseMetaData.getTypeInfo() returns incorrect precision for VARCHAR FOR BIT DATA
Date Tue, 06 Feb 2007 16:45:06 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12470633
] 

Saurabh Vyas commented on DERBY-2260:
-------------------------------------

I have a question regarding assertFalse(rs.wasNull()) in testGetTypeInfo() method in DatabaseMetaDataTest.java.
After one 'assertEquals' for precision, there is an 'assertFalse'. Why this assert is required?
This assert was failing for me (after I had added case for XML data type for precision).
Did I missed any thing in the test ?
