4D DSN-less ODBC connection
4D DSN-less ODBC connection
Took me forever to figure this out because the docs out there for 4D are minimal1 on connecting to the database without a system configured DSN using 4D’s ODBC driver.
Easy configuration of multiple data sources is crucial if you want to use CodeIgniter or any other framework that allows configuration files to control the deployment and connection to various databases.2
// get the connection resource circa 2011 so php ~v5.x 4D's database default port was `19812`
$connect=odbc_connect('DRIVER={4D v11 ODBC Driver};SSL=false;SERVER=192.168.1.100;PORT=19812;UID=user;PWD=password',"","");
I played with various different ways of doing this connection string, and found the above the most straight forward. You can leave password blank if there isn’t one.
Now if only they would make a linux odbc driver…3
DSN Configuration
If I recall correctly our 4D instance was deployed on a Mac Server and PHP a Windows IIS server. So the DSN configuration would’ve had a dialog something like below.
