Interface PreparedExpression

public interface PreparedExpression

This class is used to prepare and execute ad hoc queries.

Example: 

   Context ctx = getContext();
   PreparedExpression expr = DataAccessServiceFactory.prepareExpression
      (ctx, "application_name", 
       "declare variable $Name as xs:string external; " +
       "import schema namespace t1=\"ld:Proj/MyDS\" at \"ld:Proj/schemas/MyDS.xsd\"; " +
       "for $data in t1:func() where $data/first_name eq $Name return $data/child");
   expr.bindString(new QName("Name"), "Jim");
   DASResult result = expr.executeQuery();

Method Detail







executeQuery


DASResult<java.lang.Object> executeQuery()
                                         throws DASException




Executes the prepared query.






Returns:
DASResult.

Throws:

DASException










executeQuery


DASResult<java.lang.Object> executeQuery(RequestConfig config)
                                         throws DASException




Executes the prepared query.





Parameters:
config - A RequestConfig for controlling how the server
 will invoke this function, and for allowing return of
 out-of-band results such as server audit information. Note:
 Filtering ad-hoc queries via FilterXQuery is meaningless, so
 any FilterXQuery on this RequestConfig will be ignored.

Returns:
DASResult.

Throws:

DASException










getHelperContext


commonj.sdo.helper.HelperContext getHelperContext()




Return the SDO HelperContext associated with this
 PreparedExpression. You must use the XMLHelper, etc. from this
 HelperContext when manipulating any DataObjects returning from
 this PreparedExpression.
