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,连接的状态就好像为下一个语句调用了 mysql_real_query() 或mysql_query() 。这意味着也可以调用 mysql_store_result()、mysql_...
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. ...
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"); ...

PHP mysqli_next_result() 函数 定义和用法 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=...
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. ...
If mysql_next_result() returns an error, there are no more results. Before each call to mysql_next_result(), you must call mysql_free_result() for the current statement if it is a statement that returned a result set (rather than just a result status). After calling mysql_next_...
mysql_next_result_nonblocking()is used similarly tomysql_next_result(). For details about the latter, seeSection 5.4.51, “mysql_next_result()”. The two functions differ as follows:
