JdbcMetadataInfo

public JdbcMetadataInfo(GridKernalContext ctx)

Initializes info.

Parameters:

ctx - GridKernalContext

Method Detail

getPrimaryKeys

public Collection<JdbcPrimaryKeyMeta> getPrimaryKeys(String schemaNamePtrn,
                                                     String tblNamePtrn)

See DatabaseMetaData.getPrimaryKeys(String, String, String) for details. Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

Returns:

Collection of primary keys information for tables that matches specified schema and table name patterns.

getTablesMeta

public List<JdbcTableMeta> getTablesMeta(String schemaNamePtrn,
                                         String tblNamePtrn,
                                         String[] tblTypes)

See DatabaseMetaData.getTables(String, String, String, String[]) for details. Ignite has only one possible value for CATALOG_NAME and has only one table type so these parameters are handled on the client (driver) side. Result is ordered by (schema name, table name).

Parameters:

schemaNamePtrn - sql pattern for schema name.

tblNamePtrn - sql pattern for table name.

tblTypes - Requested table types.

Returns:

List of metadatas of tables that matches.

getColumnsMeta

public Collection<JdbcColumnMeta> getColumnsMeta(@Nullable
                                                 @Nullable ClientListenerProtocolVersion protoVer,
                                                 String schemaNamePtrn,
                                                 String tblNamePtrn,
                                                 String colNamePtrn)

See DatabaseMetaData.getColumns(String, String, String, String) for details. Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

Parameters:

protoVer - for what version of protocol to generate metadata. Early versions of protocol don't support some features like default values or precision/scale. If null, current version will be used.

Returns:

List of metadatas about columns that match specified schema/tablename/columnname criterias.

getSchemasMeta

public SortedSet<String> getSchemasMeta(String schemaNamePtrn)

See DatabaseMetaData.getSchemas(String, String) for details. Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

Parameters:

schemaNamePtrn - sql pattern for schema name filter.

Returns:

schema names that matches provided pattern.

getIndexesMeta

public SortedSet<JdbcIndexMeta> getIndexesMeta(String schemaNamePtrn,
                                               String tblNamePtrn)

See DatabaseMetaData.getIndexInfo(String, String, String, boolean, boolean) for details. Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side. Parameters unique approximate are ignored.

Returns:

Sorted by index name collection of index info, filtered according to specified criterias.
