Description

The RDO_CONNECT() function is used to connect to a data source. The numeric value returned should be saved to a variable to be used by other functions to reference the connection. Connection references start from 0 and correspond to the cursor/workarea -1. If RDO_CONNECT() returns -1, the connection failed.
