IT MUST NOT BE DISTRIBUTED WITH THE PRODUCT. NOTE: The entry points to this class are all static, for easy access via the query language. Each of the static methods instantiates an object from the class and calls methods off of that object. This allows the sharing of code across the various static methods. Constructor Summary   T_ConsistencyChecker(String schemaName, String tableName, String indexName)      Method Summary public static  String countDependencies()      Check to make sure that there are no active dependencies (stored or in memory). String If an inconsistency is found, and if DEBUG is on, then a string will be returned with more info. public static  String countOpens()      Check to make sure that there are no open conglomerates, scans or sorts. String If an inconsistency is found, and if DEBUG is on, then a string will be returned with more info. public static  void deleteFirstHeapRow(String schemaName, String tableName)      Delete the first row from the heap, without deleting it from the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. public static  void insertBadRowLocation(String schemaName, String tableName, String indexName)      Get the first row from the heap and insert it into the specified index, with a bad row location, without inserting it into the heap or the other indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Parameters:   indexName - The specified index. public static  void nullFirstHeapRow(String schemaName, String tableName)      Set all of the columns in the first row from the heap to null, without updating the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. public static  void reinsertFirstHeapRow(String schemaName, String tableName)      Get the first row from the heap and insert it into the heap again, without inserting it from the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. public static  String runConsistencyChecker()      Run all of the consistency checkers which do not take parameters. Actually, just run the ones that "make sense" to run. public static  void swapColumnsInFirstHeapRow(String schemaName, String tableName, int firstColumn, int secondColumn)      Swap the values in the specified columns of the first row from the heap, without updating the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Parameters:   firstColumn - First column #. Parameters:   secondColumn - Second column #. Constructor Detail T_ConsistencyChecker T_ConsistencyChecker(String schemaName, String tableName, String indexName) throws StandardException(Code) Method Detail countDependencies public static String countDependencies() throws StandardException, java.sql.SQLException(Code) Check to make sure that there are no active dependencies (stored or in memory). String If an inconsistency is found, and if DEBUG is on, then a string will be returned with more info. If DEBUG is off, then a simple string will be returned stating whether or not there are open scans. exception:   StandardException - Thrown on error exception:   java.sql.SQLException - Thrown on error countOpens public static String countOpens() throws StandardException(Code) Check to make sure that there are no open conglomerates, scans or sorts. String If an inconsistency is found, and if DEBUG is on, then a string will be returned with more info. If DEBUG is off, then a simple string will be returned stating whether or not there are open scans. exception:   StandardException - Thrown on error deleteFirstHeapRow public static void deleteFirstHeapRow(String schemaName, String tableName) throws StandardException(Code) Delete the first row from the heap, without deleting it from the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Nothing. exception:   StandardException - Thrown on error insertBadRowLocation public static void insertBadRowLocation(String schemaName, String tableName, String indexName) throws StandardException(Code) Get the first row from the heap and insert it into the specified index, with a bad row location, without inserting it into the heap or the other indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Parameters:   indexName - The specified index. Nothing. exception:   StandardException - Thrown on error nullFirstHeapRow public static void nullFirstHeapRow(String schemaName, String tableName) throws StandardException(Code) Set all of the columns in the first row from the heap to null, without updating the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Nothing. exception:   StandardException - Thrown on error reinsertFirstHeapRow public static void reinsertFirstHeapRow(String schemaName, String tableName) throws StandardException(Code) Get the first row from the heap and insert it into the heap again, without inserting it from the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Nothing. exception:   StandardException - Thrown on error runConsistencyChecker public static String runConsistencyChecker() throws StandardException, java.sql.SQLException(Code) Run all of the consistency checkers which do not take parameters. Actually, just run the ones that "make sense" to run. Today, that is: countOpens() String If an inconsistency is found, and if DEBUG is on, then a string will be returned with more info. If DEBUG is off, then a simple string will be returned stating whether or not there are open scans. exception:   StandardException - Thrown on error exception:   java.sql.SQLException - Thrown on error swapColumnsInFirstHeapRow public static void swapColumnsInFirstHeapRow(String schemaName, String tableName, int firstColumn, int secondColumn) throws StandardException(Code) Swap the values in the specified columns of the first row from the heap, without updating the indexes on the table. Parameters:   schemaName - The schema name. Parameters:   tableName - The table name. Parameters:   firstColumn - First column #. Parameters:   secondColumn - Second column #.
