Examples of assertTableStats()

org.apache.derbyTesting.junit.IndexStatsUtil.assertTableStats()
Asserts that the expected number of statistics exists for the specified table. @param table the target table @param expectedCount expected number of statistics @throws SQLException if obtaining the statistics fails
