C Data Dictionary

The Oracle Database Gateway for Informix translates a query that refers to an Oracle database data dictionary table into a query that retrieves the data from Informix system catalog 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. The gateway data dictionary is similar to the Oracle database data dictionary in appearance and use.

This appendix contains the following sections:

C.1 Data Dictionary Support

The following paragraphs describe the data dictionary support of the Oracle Database Gateway for Informix.

C.1.1 Informix System Catalog Tables

Informix data dictionary information is stored in the Informix database as Informix system catalog tables. All Informix system catalog tables have names prefixed with “sys”. The Informix system catalog tables define the structure of a database. When you change data definitions, Informix reads and modifies the Informix system catalog tables to add information about the user tables.

C.1.2 Accessing the Gateway Data Dictionary

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 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 Informix database:

SQL> SELECT * FROM "ALL_CATALOG"@IFMX;

When a data dictionary access query is issued, the gateway:

  1. Maps the requested table, view, or synonym to one or more Informix system catalog table names. The gateway translates all data dictionary column names to their corresponding Informix column names within the query. If the mapping involves one Informix system catalog table, the gateway translates the requested table name to its corresponding Informix system catalog table name within the query. If the mapping involves multiple Informix system catalog tables, the gateway constructs a join in the query using the translated Informix system catalog table names.

  2. Sends the translated query to Informix.

  3. Might convert the retrieved Informix data to give it the appearance of the Oracle database data dictionary table.

  4. Passes the data dictionary information from the translated Informix system catalog table to the Oracle database.

    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.

C.1.3 Direct Queries to Informix Tables

Queries issued directly to individual Informix system catalog tables are allowed but they return different results because the Informix system catalog table column names differ from those of the data dictionary view. Also, certain columns in an Informix system catalog table cannot be used in data dictionary processing.

C.1.4 Supported Views and Tables

The gateway supports the following views and tables:

Supported Views and Tables Supported Views and Tables
ALL_CATALOG ALL_COL_COMMENTS
ALL_COL_PRIVS ALL_CONS_COLUMNS
ALL_CONSTRAINTS ALL_IND_COLUMNS
ALL_INDEXES ALL_OBJECTS
ALL_SYNONYMS ALL_TAB_COLUMNS
ALL_TAB_COMMENTS ALL_TAB_PRIVS
ALL_TABLES ALL_USERS
ALL_VIEWS COLUMN_PRIVILEGES
DBA_CATALOG DBA_COL_COMMENTS
DBA_OBJECTS DBA_TABLES
DBA_TAB_COLUMNS DBA_TAB_COMMENTS
DICT_COLUMNS DICTIONARY
DUAL TABLE_PRIVILEGES
USER_CATALOG USER_COL_COMMENTS
USER_COL_PRIVS USER_CONS_COLUMNS
USER_CONSTRAINTS USER_IND_COLUMNS
USER_INDEXES USER_OBJECTS
USER_SYNONYMS USER_TAB_COLUMNS
USER_TAB_COMMENTS USER_TAB_PRIVS
USER_TABLES USER_USERS
USER_VIEWS  

No other Oracle database data dictionary tables or views are supported. If you use a view not on the list, you receive the Oracle database 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 Informix database even when access privileges for those Informix 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.

C.2 Data Dictionary Mapping

The tables in this section list Oracle data dictionary view names and the equivalent Informix system catalog tables used. A plus sign (+) indicates that a join operation is involved.

C.2.1 Default Column Values

There is a minor difference between the gateway data dictionary and a typical Oracle database data dictionary. The Oracle database columns that are missing in an Informix system catalog table are filled with zeros, spaces, null values, not-applicable values (N.A.), or default values, depending on the column type.

C.3 Gateway Data Dictionary Descriptions

The gateway data dictionary tables and views provide the following information:

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 data dictionary tables and views. Any default value is shown to the right of an item, but this is not information returned by DESCRIBE.
