What happens when you connect
When you connect to a database by selecting its database profile,
PowerBuilder writes the profile name and its connection parameters to
the registry key
HKEY_CURRENT_USERSoftwareSybasePowerBuilder19.0DatabaseProfilesPowerBuilder.
Each time you connect to a different database,
PowerBuilder overwrites the “most-recently used” profile name in the
registry with the name for the new database connection.
When you open a painter that accesses the database, you are
connected to the database you used last. PowerBuilder determines which
database this is by reading the registry.
The three-letter abbreviation for the database interface followed
by the name of the database profile displays in PowerBuilder’s main
title bar. If you are working with a DataWindow object, this visual cue
makes it easier to check that you are using the right connection.
For example, if you open the PowerBuilder Code Examples
workspace and connect to the Demo database, the title bar displays
“pbexamples – ODB [PB Demo DB V2019R3] – PowerBuilder.”
