All Implemented Interfaces:

QueryExecuterFactory, Designated

public class PlSqlQueryExecuterFactory
extends JRJdbcQueryExecuterFactory

Query executer factory for Oracle queries, both inline SQL and stored procedures. The normal JRJdbcQueryExecuterFactory can be used with Oracle for inline SQL, but not stored procedures.

To use with an oracle stored procedure that returns results via a REF CURSOR you declare a parameter of type java.sql.ResultSet, and pass that to the stored procedure. For example, if you have a stored procedure named "do_stuff" that takes a string as the first parameter and returns results via the second parameter you would use a query that looks like:
{call do_stuff($P{the_string_param}, $P{the_result_set_param})}

This factory creates Oracle query executers for SQL queries.

Method Detail

getBuiltinParameters

public Object[] getBuiltinParameters()

Description copied from interface: QueryExecuterFactory

Returns the built-in parameters associated with this query type.

These parameters will be created as system-defined parameters for each report/dataset having a query of this type.

The returned array should contain consecutive pairs of parameter names and parameter classes (e.g. {"Param1", String.class, "Param2", "List.class"}).

Specified by:

getBuiltinParameters in interface QueryExecuterFactory

Overrides:

getBuiltinParameters in class JRJdbcQueryExecuterFactory

Returns:

array of built-in parameter names and types associated with this query type

supportsQueryParameterType

public boolean supportsQueryParameterType(String className)

Description copied from interface: QueryExecuterFactory

Decides whether the query executers created by this factory support a query parameter type.

This check is performed for all $P{..} parameters in the query.

Specified by:

supportsQueryParameterType in interface QueryExecuterFactory

Overrides:

supportsQueryParameterType in class JRJdbcQueryExecuterFactory

Parameters:

className - the value class name of the parameter

Returns:

whether the parameter value type is supported
