我嘗試調用兩個存儲proceedures一個,另一個使用PHP和PDO後..但是當我嘗試這樣做,它會返回一個錯誤說無法調用MySQL的存儲過程PDO
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]:
General error: 2014 Cannot execute queries while other unbuffered queries are
active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is
only ever going to run against mysql, you may enable query buffering by setting
the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.'
正如你」我也可以看到使用MYSQL_ATTR_USE_BUFFERED_QUERY
屬性的即時通訊,但仍然出現錯誤。
$conn = new PDO("mysql:host=$dbConfig->host;dbname=".$dbConfig->name, $dbConfig->username, $dbConfig->password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
$tables = array();
$table_count = $conn->prepare("SELECT TABLE_NAME FROM information_schema.tables WHERE table_schema = 'milepostdb' AND table_name LIKE 'table_%' ");
$table_count->execute();
while ($data = $table_count->fetch(PDO::FETCH_ASSOC)) {
$table = $data["TABLE_NAME"];
//$result = $conn->prepare("SELECT * FROM $table WHERE time > DATE_ADD(NOW(), INTERVAL -1 WEEK)");//this works perfectly
$result = $conn->prepare("CALL sp_project_time_interval('$table')");
$result->execute();// place where the error triggers
$count = $result->rowCount();
if($count>0){
$exc = $conn->prepare("CALL sp_weekly_project_report('$table')");
$exc->execute();
while($finalRes = $exc->fetch(PDO::FETCH_ASSOC))
{
$tables[] = $finalRes;
}
}
}
而不是保持開放的結果集並遍歷它,做一個子查詢,而遍歷它,做'fetchAll'把所有的結果集在一個數組,然後遍歷數組了,這樣你可以關閉結果集在做子查詢之前。 – developerwjk 2015-02-18 00:50:02
我明白你在說什麼......但爲了實現它,在技術上可以請給我一個代碼 – 2015-02-18 00:53:10
