Class MariaDBDictionary

    • Field Detail

      • tableType

        public String tableType
        The MySQL table type to use when creating tables; defaults to innodb.

      • useClobs

        public boolean useClobs
        Whether to use clobs; defaults to true. Set this to false if you have an old version of MySQL which does not handle clobs properly.

      • driverDeserializesBlobs

        public boolean driverDeserializesBlobs
        Whether the driver automatically deserializes blobs.

      • optimizeMultiTableDeletes

        public boolean optimizeMultiTableDeletes
        Whether to inline multi-table bulk-delete operations into MySQL's combined DELETE FROM foo, bar, baz syntax. Defaults to false, since this may fail in the presence of InnoDB tables with foreign keys.

      • connectedConfiguration

        public void connectedConfiguration​(Connection conn)
                            throws SQLException
        Description copied from class: DBDictionary
        This method is called when the dictionary first sees any connection. It is used to initialize dictionary metadata if needed. If you override this method, be sure to call super.connectedConfiguration.
        Overrides:
        connectedConfiguration in class DBDictionary
        Throws:
        SQLException

      • getCreateTableSQL

        public String[] getCreateTableSQL​(Table table)
        Description copied from class: DBDictionary
        Return a series of SQL statements to create the given table, complete with columns. Indexes and constraints will be created separately.
        Overrides:
        getCreateTableSQL in class DBDictionary

      • getDropIndexSQL

        public String[] getDropIndexSQL​(Index index)
        Description copied from class: DBDictionary
        Return a series of SQL statements to drop the given index. Returns DROP INDEX <index name> by default.
        Overrides:
        getDropIndexSQL in class DBDictionary

      • getAddPrimaryKeySQL

        public String[] getAddPrimaryKeySQL​(PrimaryKey pk)
        Description copied from class: DBDictionary
        Return a series of SQL statements to add the given primary key to its table. Return an empty array if operation not supported. Returns ALTER TABLE <table name> ADD <pk cons sql > by default.
        Overrides:
        getAddPrimaryKeySQL in class DBDictionary

      • getDeleteTableContentsSQL

        public String[] getDeleteTableContentsSQL​(Table[] tables,
                                          Connection conn)
        Description copied from class: DBDictionary
        Create SQL to delete the contents of the specified tables. The default implementation drops all non-deferred RESTRICT foreign key constraints involving the specified tables, issues DELETE statements against the tables, and then adds the dropped constraints back in. Databases with more optimal ways of deleting the contents of several tables should override this method.
        Overrides:
        getDeleteTableContentsSQL in class DBDictionary

      • appendSelectRange

        protected void appendSelectRange​(SQLBuffer buf,

                                 boolean subselect)
        Description copied from class: DBDictionary
        If this dictionary can select ranges, use this method to append the range SQL.
        Overrides:
        appendSelectRange in class DBDictionary

      • getPreferredType

        public int getPreferredType​(int type)
        Description copied from class: DBDictionary
        Return the preferred Types type for the given one. Returns the given type by default.
        Overrides:
        getPreferredType in class DBDictionary

      • appendXmlComparison

        public void appendXmlComparison​(SQLBuffer buf,
                                String op,
                                FilterValue lhs,

                                boolean rhsxml)
        Append XML comparison.
        Overrides:
        appendXmlComparison in class DBDictionary
        Parameters:
        buf - the SQL buffer to write the comparison

      • matchErrorState

        protected int matchErrorState​(Map<Integer,​Set<String>> errorStates,
                              SQLException ex)
        Description copied from class: DBDictionary
        Determine the more appropriate type of store exception by matching the SQL Error State of the the given SQLException to the given Error States categorized by error types. Dictionary subclass can override this method and extract SQLException data to figure out if the exception is recoverable.
        Overrides:
        matchErrorState in class DBDictionary
        Parameters:
        errorStates - classification of SQL error states by their specific nature. The keys of the map represent one of the constants defined in StoreException. The value corresponding to a key represent the set of SQL Error States representing specific category of database error. This supplied map is sourced from sql-error-state-codes.xml and filtered the error states for the current database.
        ex - original SQL Exception as raised by the database driver.
        Returns:
        A constant indicating the category of error as defined in StoreException.

      • isFatalException

        public boolean isFatalException​(int subtype,
                                SQLException ex)
        Description copied from class: DBDictionary
        Determine if the given SQL Exception is fatal or recoverable (such as a timeout). This implementation always returns true (i.e. all exceptions are fatal). The current dictionary implementation can overwrite this method to mark certain exception conditions as recoverable error.
        Overrides:
        isFatalException in class DBDictionary
        Parameters:
        subtype - A constant indicating the category of error as defined in StoreException.
        ex - original SQL Exception as raised by the database driver.
        Returns:
        false if the error is fatal.

        Overrides:
