transactionobject |
The current transaction object |
Return Values
UnsignedLong. Returns the handle for
your DBMS. Transactionobject must exist, and
the database must be connected. If transactionobject is null, DBHandle returns null.
If transactionobject does not exist, an execution
error occurs. If there is not enough memory to connect to your DBMS, DBHandle returns
a negative number.
Usage
DBHandle returns a valid handle only if
you are connected to the database. It is not able to determine if
the database connection does not exist or has been lost.
PowerBuilder uses the database handle internally to communicate
with the database. If your database supports an API with functions
that PowerBuilder does not support, you can use DBHandle to
provide the handle as an argument to one of these external functions.
