You use query table API methods to retrieve
content when you run queries against a query table in Business Process
Choreographer.
The following input parameters are passed to the
methods of the query table API:
Table 1. Parameters
of the query table API| Parameter |
Optional |
Type and description |
|---|
| Query table name |
No |
java.lang.String |
| The unique name of the query table. |
| Filter options |
Yes |
com.ibm.bpe.api.FilterOptions
if the Business Flow Manager Enterprise JavaBeans is used or com.ibm.task.api.FilterOptions if
the Human Task Manager Enterprise JavaBeans is used. |
| Options which can be used to define the query.
For example, a query threshold is set on this parameter to limit the
number of results returned. |
| Authorization options |
Yes |
com.ibm.bpe.api.AuthorizationOptions or com.ibm.bpe.api.AdminAuthorizationOptions if
the Business Flow Manager Enterprise JavaBeans is used. com.ibm.task.api.AuthorizationOptions or com.ibm.task.api.AdminAuthorizationOptions if
the Human Task Manager Enterprise JavaBeans is used. |
| Authorization can be further constrained if
instance-based authorization is used. For query tables
which require role-based authorization, an instance of AdminAuthorizationOptions
must be passed. |
| Parameters |
Yes |
A java.util.List of com.ibm.bpe.api.Parameter if
the Business Flow Manager Enterprise JavaBeans is used or com.ibm.task.api.Parameter if
the Human Task Manager Enterprise JavaBeans is used. |
| This parameter is used to pass user parameters,
which are specified in a filter or selection criterion on a composite
query table. |
A query is run on one specific query table only.
The relationship between multiple query tables is defined with composite
query tables. In terms of the query API (as distinct from the query
table API), this corresponds to database views.
You specify filters and selection criteria in
expressions during query table development using the Query Table Builder.
For more information, refer to the information center topic about
composite query tables and the topic about filter and search criteria
of query tables. For information about the Query Table Builder, see
the SupportPacs site. Look for PA71 WebSphere Process Server -
Query Table Builder. To access the link, see the related references
section of this topic.
