Explanation: Unqualified successful execution or successful execution with one or more warnings. If SQLWARN0 is
blank, there are no warnings. If SQLWARN0 = W, at least one of the other warning indicators in the SQLCA has been
set to indicate a warning condition. For example, SQLWARN1 is used to indicate that a value of a string column was
truncated when assigned to a host variable.
SQLSTATE: 00000 for unqualified successful execution
SQLSTATE: 01ddd for successful execution with warning 'ddd'.
