Method Details

restrictMemberTypes

protected boolean restrictMemberTypes()

Description copied from class: RolapNativeSet

Returns whether certain member types (e.g. calculated members) should disable native SQL evaluation for expressions containing them.

If true, expressions containing calculated members will be evaluated by the interpreter, instead of using SQL.

If false, calc members will be ignored and the computation will be done in SQL, returning more members than requested. This is ok, if the superflous members are filtered out in java code afterwards.

Specified by:

restrictMemberTypes in class RolapNativeSet

Returns:

whether certain member types should disable native SQL evaluation
