Class FBDatabaseMetaData

Implemented Interfaces:
DatabaseMetaData, FirebirdDatabaseMetaData

public class FBDatabaseMetaData
extends java.lang.Object
implements FirebirdDatabaseMetaData

Comprehensive information about the database as a whole.

Many of the methods here return lists of information in the form of ResultSet objects. You can use the normal ResultSet methods such as getString and getInt to retrieve the data from these ResultSet. If a given form of metadata is not available, these methods should throw an SQLException.

Some of these methods take arguments that are String patterns. These arguments all have names such as fooPattern. Within a pattern String, "%" means match any substring of 0 or more characters, and "_" means match any one character. Only metadata entries matching the search pattern are returned. If a search pattern argument is set to a null ref, that argument's criteria will be dropped from the search.

An SQLException will be thrown if a driver does not support a meta data method. In the case of methods that return a ResultSet, either a ResultSet (which may be empty) is returned or a SQLException is thrown.

        Gets a description of the foreign key columns in the foreign key table that reference the primary key columns of the primary key table (describe how one table imports another's key). This should normally return a single foreign key/primary key pair (most tables only import a foreign key from a table once.) They are ordered by FKTABLE_CAT, FKTABLE_SCHEM, FKTABLE_NAME, and KEY_SEQ.

        Each foreign key column description has the following columns:

        1. PKTABLE_CAT String => primary key table catalog (may be null)
        2. PKTABLE_SCHEM String => primary key table schema (may be null)

        8. FKCOLUMN_NAME String => foreign key column name being exported
        9. KEY_SEQ short => sequence number within foreign key
        10. UPDATE_RULE short => What happens to foreign key when primary is updated:
          • importedNoAction - do not allow update of primary key if it has been imported
          • importedKeyCascade - change imported key to agree with primary key update
          • importedKeySetNull - change imported key to NULL if its primary key has been updated
          • importedKeySetDefault - change imported key to default values if its primary key has been updated
          • importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
          • DELETE_RULE short => What happens to the foreign key when primary is deleted.
            • importedKeyNoAction - do not allow delete of primary key if it has been imported
            • importedKeyCascade - delete rows that import a deleted key
            • importedKeySetNull - change imported key to NULL if its primary key has been deleted
            • importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
            • importedKeySetDefault - change imported key to default if its primary key has been deleted
            • FK_NAME String => foreign key name (may be null)

                                  Gets a comma-separated list of string functions. These are the X/Open CLI string function names used in the JDBC function escape clause.
                                  Returns:
                                  the list

                                  getSuperTables

                                  public ResultSet getSuperTables(String catalog,
                                                                  String schemaPattern,
                                                                  String tableNamePattern)
                                              throws SQLException
                                  Retrieves a description of the table hierarchies defined in a particular schema in this database.

                                  Only supertable information for tables matching the catalog, schema and table name are returned. The table name parameter may be a fully- qualified name, in which case, the catalog and schemaPattern parameters are ignored. If a table does not have a super table, it is not listed here. Supertables have to be defined in the same catalog and schema as the sub tables. Therefore, the type description does not need to include this information for the supertable.

                                  Each type description has the following columns:

                                  1. TABLE_CAT String => the type's catalog (may be null)
                                  2. TABLE_SCHEM String => type's schema (may be null)
                                  3. TABLE_NAME String => type name
                                  4. SUPERTABLE_NAME String => the direct super type's name

                                  Note: If the driver does not support type hierarchies, an empty result set is returned.

                                  Parameters:
                                  catalog - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria
                                  schemaPattern - a schema name pattern; "" retrieves those without a schema
                                  tableNamePattern - a table name pattern; may be a fully-qualified name
                                  Returns:
                                  a ResultSet object in which each row is a type description

                                  getSuperTypes

                                  public ResultSet getSuperTypes(String catalog,
                                                                 String schemaPattern,
                                                                 String tableNamePattern)
                                              throws SQLException
                                  Retrieves a description of the user-defined type (UDT) hierarchies defined in a particular schema in this database. Only the immediate super type/sub type relationship is modeled.

                                  Only supertype information for UDTs matching the catalog, schema, and type name is returned. The type name parameter may be a fully-qualified name. When the UDT name supplied is a fully-qualified name, the catalog and schemaPattern parameters are ignored.

                                  If a UDT does not have a direct super type, it is not listed here. A row of the ResultSet object returned by this method describes the designated UDT and a direct supertype. A row has the following columns:

                                  1. TYPE_CAT String => the UDT's catalog (may be null)
                                  2. TYPE_SCHEM String => UDT's schema (may be null)
                                  3. TYPE_NAME String => type name of the UDT
                                  4. SUPERTYPE_CAT String => the direct super type's catalog (may be null)
                                  5. SUPERTYPE_SCHEM String => the direct super type's schema (may be null)
                                  6. SUPERTYPE_NAME String => the direct super type's name

                                  Note: If the driver does not support type hierarchies, an empty result set is returned.

                                  Parameters:
                                  catalog - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria
                                  schemaPattern - a schema name pattern; "" retrieves those without a schema
                                  tableNamePattern - a UDT name pattern; may be a fully-qualified name
                                  Returns:
                                  a ResultSet object in which a row gives information about the designated UDT

                                  getSystemFunctions

                                  public String getSystemFunctions()
                                              throws SQLException
                                  Gets a comma-separated list of system functions. These are the X/Open CLI system function names used in the JDBC function escape clause.
                                  Returns:
                                  the list

                                  Gets a description of the access rights for each table available in a catalog. Note that a table privilege applies to one or more columns in the table. It would be wrong to assume that this priviledge applies to all columns (this may be true for some systems but is not true for all.)

                                  Only privileges matching the schema and table name criteria are returned. They are ordered by TABLE_SCHEM, TABLE_NAME, and PRIVILEGE.

                                  Each privilige description has the following columns:

                                  1. TABLE_CAT String => table catalog (may be null)
                                  2. TABLE_SCHEM String => table schema (may be null)

                                  6. PRIVILEGE String => name of access (SELECT, INSERT, UPDATE, REFRENCES, ...)
                                  7. IS_GRANTABLE String => "YES" if grantee is permitted to grant to others; "NO" if not; null if unknown
                                  Parameters:
                                  catalog - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria
                                  schemaPattern - a schema name pattern; "" retrieves those without a schema
                                  tableNamePattern - a table name pattern
                                  Returns:
                                  ResultSet - each row is a table privilege description

                                  public ResultSet getTableTypes()
                                              throws SQLException
                                  Gets the table types available in this database. The results are ordered by table type.

                                  The table type is:

                                  1. TABLE_TYPE String => table type. Typical types are "TABLE", "VIEW", "SYSTEM TABLE", "GLOBAL TEMPORARY", "LOCAL TEMPORARY", "ALIAS", "SYNONYM".
                                  Returns:

                                                             types[] )
                                              throws SQLException
                                  Gets a description of tables available in a catalog.

                                  Only table descriptions matching the catalog, schema, table name and type criteria are returned. They are ordered by TABLE_TYPE, TABLE_SCHEM and TABLE_NAME.

                                  Each table description has the following columns:

                                  1. TABLE_CAT String => table catalog (may be null)
