Using Database Operations

Oracle Adapter Database Operations (BPEL)

The Oracle Adapter uses a number operations to query the Oracle database. Within a BPEL business process, the Oracle Adapter uses BPEL Activities to perform basic outbound database operations, including:

Insert
Update
Delete
SelectOne
SelectMultiple
SelectAll

In addition to these outbound operations, the Oracle Adapter also employs the inbound Activity ReceiveOne within a Prepared Statement OTD.

Activity Input and Output

The Sun SeeBeyond Enterprise Desinger– Business Rules Designer includes Input and Output columns to map and transform data between Activities displayed on the Business Process Canvas.

Figure 1–7 displays the business rules between the FileClient.write and otdOracle.Db_employeeDelete Activities. In this example, the whereClause appears on the Input side.

Figure 1–7 Input and Output Between Activities

The following table lists the expected Input and Output of each database operation Activity.

Table 1–7 Oracle Operations


eInsight Operations	Activity Input	Activity Output
SelectAll	where() clause (optional)	Returns all rows that fit the condition of the where() clause.
SelectMultiple	number of rows where() clause (optional)	Returns the number of rows specified that fit the condition of the where() clause, and the number of rows to be returned. For example: If the number of rows that meet the condition are 5 and the number of available rows are 10, then only 5 rows will be returned. Alternately, if the number of rows that meet the condition are 20, but if the number of available rows are 10, then only 10 rows are returned.
SelectOne	where() clause (optional)	Returns the first row that fits the condition of the where() clause.
Insert	definition of new item to be inserted	Returns status.
Update	where() clause	Returns status.
Delete	where() clause	Returns status.
