ResultSet drillThroughInternal(int maxRowCount,
                               int firstRowOrdinal,
                               List<OlapElement> fields,

                        throws OlapException

Executes drill-through on this cell.

Not a part of the public API. Package-protected because this method also implements the DRILLTHROUGH statement.

Parameters:

maxRowCount - Maximum number of rows to retrieve, <= 0 if unlimited

firstRowOrdinal - Ordinal of row to skip to (1-based), or 0 to start from beginning

fields - List of fields to return, expressed as MDX expressions.

extendedContext - If true, add non-constraining columns to the query for levels below each current member. This additional context makes the drill-through queries easier for humans to understand.

logger - Logger. If not null and debug is enabled, log SQL here

rowCountSlot - Slot into which the number of fact rows is written

Returns:

Result set

Throws:

OlapException - on error

setValue

public void setValue(Object newValue,
                     AllocationPolicy allocationPolicy,
                     Object... allocationArgs)
              throws OlapException

Specified by:

setValue in interface Cell

Throws:

OlapException
