codeigniter：命令不同步;你现在不能运行这个命令

Question

我应用了所有可能的答案，但仍然是同样的问题。 也尝试了

$this->db->reconnect();

我的查询没有问题

mycode的：

public function GetdistributorsDetails($username){
        $sql = "SELECT u.FirstName, u.Email, u.Telephone, u.MobileNumber, u.AlternateMobileNumber, ud.Address1, ud.Pincode,ud.City,s.Statename FROM users u JOIN userdetails ud ON ud.UserId = u.UserId JOIN states s ON s.StateId = ud.StateId WHERE u.Username = ? ";
        $result = $this->db->query($sql,array($username));
        return $result->result_array();
    }

Answer 1

将以下代码添加到/system/database/drivers/mysqli/mysqli_result.php

 function next_result()
 {
     if (is_object($this->conn_id))
     {
         return mysqli_next_result($this->conn_id);
     }
 }

然后在模型中调用存储过程

$query    = $this->db->query("CALL test()");
$res      = $query->result();

//add this two line 
$query->next_result(); 
$query->free_result(); 
//end of new code

return $res;

Answer 2

您可以在通话后使用此功能

mysqli_next_result( $this->db->conn_id );

Answer 3

如果你在同一个函数中使用多个查询make，只需使用这个： $这 - ＆GT; DB-＆GT;关闭（）;

Answer 4

如果存储过程返回多个结果，请尝试在查询之间添加以下代码：

$storedProcedure = 'CALL test(inputParam, @outputParam)';
$this->db->query($storedProcedure);    

$conn = $this->db->conn_id;
do {
    if ($result = mysqli_store_result($conn)) {
        mysqli_free_result($result);
    }
} while (mysqli_more_results($conn) && mysqli_next_result($conn));

$sql = 'SELECT @outputParam;';
$this->db->query($sql); 

Answer 5

只需在其中添加 next_result 函数 system\database\drivers\mysqli\mysqli_result.php 文件

public function next_result(){
    if(is_object($this->conn_id) && mysqli_more_results($this->conn_id)){
        return mysqli_next_result($this->conn_id);
    }
}

调用查询函数

  $result = $this->db->query("CALL {$Name}({$Q})",$Param);
  $result->next_result();
  return  $result;
    

Answer 6

Here is example if you don't want change any thing in mysqli drivers files 

$sql = "CALL procedureName(IntParam,'VarcharParm1','VaracharParm2','VarcharParm3');";
$query = $this->db->query($sql);
mysqli_next_result( $this->db->conn_id );
$query->free_result();

these are important line place after to remove the error 
mysqli_next_result( $this->db->conn_id );
$query->free_result();
