Description
An OraDatabase interface represents a user session to an Oracle database and
provides methods for SQL and PL/SQL execution.
Remarks
An OraDatabase interface in the Oracle8i release adds additional methods for controlling transactions and creating
interfaces representing instances of Oracle object types. Attributes of schema
objects can be retrieved using the Describe method of the OraDatabase interface.
In previous releases, an OraDatabase object is created by invoking the OpenDatabase method of an OraSession interface. The network alias, user name, and password are passed as arguments
to this method. In the Oracle8i release, invocation of this method results in implicit creation of an
OraServer object.
As described in the OraServer interface description, an OraDatabase object can also be created using the OpenDatabase method of the OraServer interface.
Transaction control methods are available at the OraDatabase (user session)
level. These methods include:
· BeginTrans
· CommitTrans
· Rollback
For example:
MyDatabase.BeginTrans
MyDatabase.ExecuteSQL("delete from emp where empno = 1234")
MyDatabase.CommitTrans
Note: If the AutoCommit property is set to True, transactions are committed automatically and you do
not need to use the transactions control methods.
