PHP からストアド プロシージャを呼び出そうとしていますが、それが別のストアド プロシージャを呼び出します。コマンドラインでストアド プロシージャ コールを実行すると、複数の結果が返されますが、php を介して呼び出すと 1 つの結果しか返されません。これが私の手順です

PHP からは、最初の結果セットのみを見ています。コマンドラインから、すべての結果セットを吐き出すだけです。

上記の各ストアド プロシージャ呼び出しは、新しい一意の結果セットを生成しています (さまざまなフィールドが可能など)。

修正するには、次の結果セットが存在する場合は、次の結果セットに移動できます。

使用するodbc_next_result ( resource $result_id )

または、Mysqli を使用して、次の 3 つのコマンドを使用できます。

$result = $connection->multi_query("select * from foo...."); $result = $connection->store_result(); $connection->next_result();

コードを例として使用すると、次のように do..while ループ内で結果を出力するコードをラップできます。

$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());
