Always got a error popup window (actually not an error)

QuestionsAlways got a error popup window (actually not an error)
Jim Poon asked 2 years ago

actually, it is NOT an error. It is the content of the mysql result. I don’t know why.



environment: laravel

data backend: mysql

Couldn’t execute query. No database selected – SELECT count(*) as c FROM (SELECT * FROM T000115841008282474740 WHERE 1=1) pg_tmp

Checked from internal application log:

data connection OK

table EXISTS.

any hints about this?


in jqgrid.dist.php:

error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);

in application code:

$g->con->debug = 0; // changed from 0 to 1

Error shows database connection issue: No database selected

Please confirm if you are passing correct database credentials to the constructor. e.g.

$db_conf = array(
“server” => PHPGRID_DBHOST,
“password” => PHPGRID_DBPASS,
“database” => PHPGRID_DBNAME

$grid = new jqgrid($db_conf);

And these constants are defined before you call.

I am using the following db_conf. is this ok?  $db_conf = array(
“type” => ‘mysqli’,
“server” => env(‘DB_HOST’),
“user” => env(‘DB_USERNAME’),
“password” => env(‘DB_PASSWORD’),
“database” => env(‘DB_DATABASE’),
‘wait_timeout’ => ‘1000’,
‘interactive_timeout’ => ‘1000’,
‘net_read_timeout’ => ‘1000’,
‘unix_socket’ => env(‘DB_SOCKET’, ”),
‘charset’ => ‘utf8mb4’,
‘collation’ => ‘utf8mb4_unicode_ci’,
‘prefix’ => ”,
‘strict’ => false,
‘engine’ => null,

DB_DATABASE is defined in laravel .env file

Abu answered 2 years ago

I am sending you a sample laravel controller that uses datagrid.

Looks like env(…) data is not being fetched.

You can also try downloading laravel 5.5 complete code from here and compare with your copy.

Jim Poon answered 2 years ago

Yes. It is really an issue from old laravel 5.x in getting the env string.


problem fixed now
