The RaiseError attribute can be used to force errors to raise exceptio
+ns rather than simply return error codes in the normal way. It is "of
+f" by default. When set "on", any method which results in an error wi
+ll cause the DBI to effectively do a die("$class $method failed: $DBI
+::errstr"), where $class is the driver class and $method is the name
+of the method that failed. E.g.,
DBD::Oracle::db prepare failed: ... error text here ...
