Using JDBC/ODBC Operations
Database operations in the JDBC eWay are used to access the JDBC database. Database
operations are either accessed through Activities in BPEL, or through methods called
from a JCD Collaboration.

5.1
JDBC eWay Database Operations (BPEL)
Within a BPEL business process, the JDBC eWay uses BPEL Activities to perform basic
outbound database operations, including:
ƒ Insert
ƒ Update
ƒ Delete
ƒ SelectOne
ƒ SelectMultiple
ƒ SelectAll
In addition to these outbound operations, the JDBC eWay also employs the inbound
Activity ReceiveOne within a Prepared Statement OTD.
The ability to perform any of the above methods using a table OTD may not be possible
with all third-party drivers. You have to use a Prepared Statement to perform such an
operation. Check with the respective driver’s vendor for further information. This
feature is known as Updatable ResultSet.
