The Oracle Transparent Gateway for Ingres II translates a query that refers to an Oracle database server data dictionary table into a query that retrieves the data from Ingres II system tables. You perform queries on data dictionary tables over the database link in the same way you query data dictionary tables in the Oracle database server. The gateway data dictionary is similar to the Oracle database server data dictionary in appearance and use.
This appendix contains the following sections:
The following paragraphs describe the data dictionary support of the Oracle Transparent Gateway for Ingres II.
Ingres II data dictionary information is stored in the Ingres II database as Ingres II system tables. All Ingres II system tables have names prefixed with ÒsysÓ. The Ingres II system tables define the structure of a database. When you change data definitions, Ingres II reads and modifies the Ingres II system tables to add information about the user tables.
Accessing a gateway data dictionary table or view is identical to accessing a data dictionary in an Oracle database. You issue a SQL SELECT statement specifying a database link. The Oracle database server data dictionary view and column names are used to access the gateway data dictionary in an Oracle database. Synonyms of supported views are also acceptable. For example, the following statement queries the data dictionary table ALL_CATALOG to retrieve all table names in the Ingres II database:
SQL> SELECT * FROM "ALL_CATALOG"@INGR;
When a data dictionary access query is issued, the gateway:
Maps the requested table, view, or synonym to one or more Ingres II system table names. The gateway translates all data dictionary column names to their corresponding Ingres II column names within the query. If the mapping involves one Ingres II system table, the gateway translates the requested table name to its corresponding Ingres II system table name within the query. If the mapping involves multiple Ingres II system tables, the gateway constructs a join in the query using the translated Ingres II system table names.
Sends the translated query to Ingres II.
Might convert the retrieved Ingres II data to give it the appearance of the Oracle database server data dictionary table.
Passes the data dictionary information from the translated Ingres II system table to the Oracle database server.
Note:
The values returned when querying the gateway data dictionary might not be the same as the ones returned by the Oracle SQL*Plus DESCRIBE command.Queries issued directly to individual Ingres II system tables are allowed but they return different results because the Ingres II system table column names differ from those of the data dictionary view. Also, certain columns in an Ingres II system table cannot be used in data dictionary processing.
The gateway supports the following views and tables:
| Supported View and Tables | Supported Views and Tables |
|---|---|
| ALL_CATALOG | ALL_COL_COMMENTS |
| ALL_CONS_COLUMNS | ALL_CONSTRAINTS |
| ALL_INDEXES | ALL_OBJECTS |
| ALL_SYNONYMS | ALL_TAB_COLUMNS |

| USER_INDEXES | USER_OBJECTS |
| USER_SYNONYMS | USER_TAB_COLUMNS |
| USER_TAB_COMMENTS | USER_TABLES |
| USER_USERS | USER_VIEWS |
No other Oracle database server data dictionary tables or views are supported. If you use a view not on the list, you receive the Oracle database server error code for no more rows available.
Queries through the gateway of any data dictionary table or view beginning with ALL_ can returns rows from the Ingres II database even when access privileges for those Ingres II objects have not been granted. When querying an Oracle database with the Oracle data dictionary, rows are returned only for those objects you are permitted to access.
The tables in this section list Oracle data dictionary view names and the equivalent Ingres II system tables used. A plus sign (+) indicates that a join operation is involved.

There is a minor difference between the gateway data dictionary and a typical Oracle database server data dictionary. The Oracle database server columns that are missing in an Ingres II system table are filled with zeros, spaces, null values, not-applicable values (N.A.), or default values, depending on the column type.
The gateway data dictionary tables and views provide the following information:
Name, data type, and width of each column
The contents of columns with fixed values
They are described here with information retrieved by an Oracle SQL*Plus DESCRIBE command. The values in the Null? column might differ from the Oracle database server data dictionary tables and views. Any default value is shown to the right of an item, but this is not information returned by DESCRIBE.
