Examples of dropStatisticsDescriptors()

org.apache.derby.iapi.sql.dictionary.DataDictionary.dropStatisticsDescriptors()
Drops all statistics descriptors for a given table/index column combination. If the index is not specified, then all statistics for the table are dropped. @param tableUUID UUID of the table @param referenceUUID UUID of the index. This can be null. @param tc Transcation Controller to use.
