php - 从 php 调用嵌套存储过程

Question

我试图从 php 调用一个存储过程，而 php 又调用另一个存储过程。当我在命令行中运行存储过程调用时，它会返回多个结果，而通过 php 调用时只会返回一个结果。这是我的程序

Answer 1

从 PHP 中，您仅查看第一个结果集。从命令行，它只是输出所有结果集。

上面的每个存储过程调用都会生成一个新的唯一结果集(可能有不同的字段等)

要修复此问题，您可以移至下一个结果集(如果存在):

使用odbc_next_result(资源$result_id)

或者，使用 Mysqli，您可以使用以下三个命令:

$result = $connection->multi_query("从 foo 选择 *...");$结果 = $连接->store_result();$connection->next_result();

以您的代码为例，您可以将输出结果的代码包装在 do..while 循环中，如下所示:

$result= $mysqli->multi_query("SELECT first_id,second_id from pair_find");

do {
  $result = $mysqli->store_result();

  while($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
  {
     print_r($row);
  }
} while ($mysqli->next_result());
