mysql_next_result() 读取下一个语句结果并返回一个状态以指示是否存在更多结果。如果 mysql_next_result() 返回错误,则没有更多结果。 在每次调用 mysql_next_result() 之前,如果当前语句是返回结果集(而不仅仅是结果状态)的语句,则必须为当前语句调用 mysql_free_result()。 在调用 mysql_next_result() 之后...
在MySQL中,当处理多结果集查询时,mysql_next_result()函数起到了关键作用。此函数用于读取并切换到查询结果集的下一项,确保应用程序能正确处理后续的数据。在使用mysql_next_result()之前,如果前一次查询返回了结果集,务必先调用mysql_free_result()释放资源。调用mysql_next_result()后,连接的状态...
mysqli next result - 语法 bool mysqli_next_result ( mysqli $link ); 1. 它从mysqli_multi_query()准备下一个输出集。 mysqli next result - 返回值 成功时返回TRUE,失败时返回FALSE。 mysqli next result - 示例 <?php $connection_mysql=mysqli_connect("localhost","user","password","db"); ...
mysqli_next_result() 函数为mysqli_multi_query()准备下一个结果集。 语法 mysqli_next_result(connection); 执行多个针对数据库的查询。请使用 mysqli_next_result() 函数来准备下一个结果集: <?php//假定数据库用户名:root,密码:123456,数据库:RUNOOB$con=mysqli_connect("localhost","root","123456",...

It is also possible to test whether there are more results by callingmysql_more_results(). However, this function does not change the connection state, so if it returns true, you must still callmysql_next_result()to advance to the next result. ...
