Question

I applied all the possible answers but still same problem.
also tried
$this->db->reconnect();
there is no problem in my query
MyCode:
public function GetdistributorsDetails($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

add following code into /system/database/drivers/mysqli/mysqli_result.php
function next_result()
{
if (is_object($this->conn_id))
{
return mysqli_next_result($this->conn_id);
}
}
then in model when you call Stored Procedure
$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

you can use this after call
mysqli_next_result( $this->db->conn_id );

Answer 3

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();

Answer 4

Just use this one if you use multiple query make in same function:
$this->db->close();

Answer 5

If your stored procedure returns more than one result, try to add this code between the queries:
$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 6

Just add next_result function in
system\database\drivers\mysqli\mysqli_result.php file
public function next_result(){
if(is_object($this->conn_id) && mysqli_more_results($this->conn_id)){
return mysqli_next_result($this->conn_id);
}
}
To call query function
$result = $this->db->query("CALL {$Name}({$Q})",$Param);
$result->next_result();
return $result;
