025/**
026 * Allows specification of alternate column names for resultset mapping.
027 * <p>
028 * Useful in situations where column names are ugly, inconsistent, or do not map well to camel-case Java property names.
029 * <p>
030 * For example:
031 *
032 * <pre>
033 * class Example {
034 *   &#064;DatabaseColumn({ &quot;systok&quot;, &quot;sys_tok&quot; })
035 *   UUID systemToken;
036 *
037 *   UUID getSystemToken() {
038 *     return systemToken;
039 *   }
040 *
041 *   void setSystemToken(UUID systemToken) {
042 *     this.systemToken = systemToken;
043 *   }
044 * }
045 *
046 * database.queryForObject(&quot;SELECT systok FROM example&quot;, Example.class);
