Interface OlapParameterMetaData

All Superinterfaces:

ParameterMetaData, Wrapper

public interface OlapParameterMetaData
extends ParameterMetaData

Extension to ParameterMetaData for parameters of OLAP statements.

Chief differences:

• An OLAP statement parameter has a name.
• An OLAP statement parameter may be a member. If this is the case, the ParameterMetaData.getParameterType(int) method returns Types.OTHER.
• An additional method getParameterOlapType(int) provides extra type information; in particular, the hierarchy that a member parameter belongs to.

Parameters to an OLAP statement must have default values, and therefore it is not necessary to set every parameter.
