I have a table which has a clumn id
and a column isadmin
.
I want to execute this query, which works just fine:
$query = "SELECT id FROM mytable WHERE isadmin = TRUE;";
But instead of getting multiple rows I would like to get one row in csv format. I found this link and created the following query, which does not work, I get a mysql error:
$query = "SELECT GROUP_CONCAT(id SEPERATOR ',') FROM mytable WHERE isadmin = TRUE;";
The error message is:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SEPERATOR ', ') FROM mytable WHERE isadmin = TRUE' at line 1
If this is not enough information just tell me and I will provide them.

The comma is the defaul separator so you don't need
SELECT GROUP_CONCAT(id ) FROM mytable WHERE isadmin = TRUE;
anyway is separator and nt seperator
SELECT GROUP_CONCAT(id SEPARATOR ',') FROM mytable WHERE isadmin = TRUE;
