Hi,
Modified the isEquivalent method to throw an exception like this.. is
it correct..
protected boolean isEquivalent(ValueNode o) throws StandardException
{
//Thread.dumpStck();
if (isSameNodeType(o))
{
BaseColumnNode other = (BaseColumnNode)o;
return other.tableName.equals(other.tableName)
&& other.columnName.equals(columnName);
}
if (1==1) {
throw StandardException.newException("Exception in
equivalent for test");
}
return false;
}
}
Also all of a sudden i started getting
1) TriggerTests:embeddedjava.sql.SQLException: No suitable driver
