 public boolean insertsAreDetected(int type) throws SQLException

Implements JDBC 2.0 DatabaseMetaData.insertsAreDetected. Indicates whether or not a visible row insert can be detected by calling ResultSet.rowInserted(). This method always return false since Oracle JDBC driver doesn't detect row changes.

Parameters:

result - set type, i.e. ResultSet.TYPE_XXX

Returns:

false always

Throws: SQLException

if a database access error occurs

 public boolean supportsBatchUpdates() throws SQLException

Implements JDBC 2.0 DatabaseMetaData::supportBatchUpdates. Indicates whether the driver supports batch updates.

Returns:

true if the driver supports batch updates; false otherwise

 public ResultSet getUDTs(String catalog,
                          String schemaPattern,
                          String typeNamePattern,
                          int types[]) throws SQLException

Implements JDBC 2.0 DatabaseMetaData::getUDTs. Gets a description of the STRUCT types defined in a particular schema.

Only types matching the schema, type name and type criteria are returned. They are ordered by DATA_TYPE, TYPE_SCHEM and TYPE_NAME. The type name parameter may be a fully-qualified name. In this case, the catalog and schemaPattern parameters are ignored.

Each type description has the following columns:

1. TYPE_CAT String => the type's catalog which is always null
2. TYPE_SCHEM String => type's schema
3. TYPE_NAME String => type name
4. CLASS_NAME String => Java class name
5. DATA_TYPE String => type value defined in java.sql.Types. Only STRUCT is supported.
6. REMARKS String => explanatory comment on the type

Parameters:

catalog - is ignored since Oracle database doesn't support catalog for structured types

schemaPattern - a schema name pattern; "" retrieves those without a schema

typeNamePattern - a type name pattern; may be a fully-qualified name

types - a list of user-named types to include (Oracle only STRUCT) supports; null returns all types

Returns:

ResultSet - each row is a type description

Throws: SQLException

if a database access error occurs
