Question

How to make this code work on Codeigniter by echo total mysql database tabels Size?
SELECT table_schema "Data Base Name",
sum( data_length + index_length ) / 1024 /
1024 "Data Base Size in MB",
sum( data_free )/ 1024 / 1024 "Free Space in MB"
FROM information_schema.TABLES
GROUP BY table_schema;
This is how to echo total mysql database tabels Rows:
<?php
$sqlx = $this->db->list_tables();
$finalCount = 0;
foreach ($sqlx as $table) {
$counteachrow = $this->db->count_all_results($table);
$finalCount += $counteachrow;
}
?>
<?php echo $finalCount; ?>

Answer 1

Create new model
<?php
class Database_model extends CI_Model {
public function __construct()
{
parent::__construct();
}
public function get_database_size() {
$query = "SELECT table_schema 'Data Base Name', sum( data_length + index_length ) / 1024 / 1024 'Data Base Size in MB', sum( data_free )/ 1024 / 1024 'Free Space in MB'
FROM information_schema.TABLES
GROUP BY table_schema";
$result = $this->db->query($query);
return $result->result_array();
}
public function get_total_rows() {
$sqlx = $this->db->list_tables();
$finalCount = 0;
foreach ($sqlx as $table) {
$counteachrow = $this->db->count_all_results($table);
$finalCount += $counteachrow;
}
return $finalCount;
}
}
and to your controller
$database_size = $this->database_model->get_database_size();
$total_rows = $this->database_model->get_total_rows();

public function get_database_size() {
$sql = "SELECT table_schema AS db_name, round((sum(data_length + index_length) / 1024 / 1024), 2) AS db_size_mb FROM information_schema.TABLES WHERE table_schema = DATABASE() GROUP BY table_schema ;";
$query = $this->db->query($sql);
if ($query->num_rows() > 0) {
$row = $query->row();
$size = $row->db_size_mb;
return $size;
}
else
{
return false;
}
}
