Catalogs Shared by All Ingres Tools
The following extended system catalogs are used by all Ingres tools:
• ii_encodings
• ii_id
• ii_locks
• ii_longremarks
• ii_objects
ii_encodings Catalog
The ii_encodings catalog contains 4GL frames and procedures encoded into a compact and portable form. Objects in this catalog are referred to as encoded objects.
This catalog is structured as btree unique on the encode_object and encode_sequence columns:
Column Name
Data Type
Description
object_id
integer
Currently not used. Is set to either 0 or the same value as the encode_object column.
encode_object
integer
The object ID for this encoded object. Various other information about this encoded object (such as name and owner) is kept in the ii_objects catalog.
encode_sequence
smallint
A sequence number, starting from 0, for the rows comprising a single encoded object. Because objects, for example a 4GL frame, can be arbitrarily long, an arbitrary number of ii_encodings rows are required to encode the object.
encode_estring
varchar
(1990)
A segment of the encoded string.
ii_id Catalog
The ii_id catalog is a heap table containing one column with a single row. The value in this catalog is the highest object ID currently allocated in this database. For a newly created database, this value is initialized to 10000 and can grow as large as the largest positive integer value. Object IDs below 10000 are reserved for system use:
Column Name
Data Type
Description
object_id
integer
The highest current object ID in this database.
ii_locks Catalog
The ii_locks catalog is used by ABF, Vision, and OpenROAD to manage concurrent user access to applications and application components (such as frames or procedures). The format of ii_locks is as follows:
Column Name
Data Type
Description
entity_id
integer
Object ID of the locked object (application or application component).
session_id
integer
ID of the user session that locked the object.
locked_by
varchar(32)
User ID that locked the object.
lock_date
char(25)
Date locked.
lock_type
varchar(16)
Type of lock:
write if an application component is locked.
refresh if a concurrent application user has changed the application flow diagram (possibly affecting other users' screens).
entry if no change to flow diagram.
ii_longremarks Catalog
The ii_longremarks catalog contains the “long remarks” text associated with user interface objects. Only those objects that have an associated long remark are entered in this catalog. Consequently, unless all objects being selected have a long remark entered, joins between ii_objects and ii_longremarks must be outer joins. For an example of an outer join between the ii_objects and ii_longremarks catalogs, see Sample Queries for the Extended System Catalogs for SQL. The current implementation restricts long remarks to a single row; the sequence column is provided for a future enhancement to allow remarks of arbitrary length.
The ii_longremarks catalog is structured as btree unique on the object_id and remark_sequence columns:
Column Name
Data Type
Description
object_id
integer
Object ID of the user interface object this remark belongs to. Various other information about this object (such as name, owner and object class) is kept in the ii_objects catalog.
remark_sequence
integer
A sequence number for (future) representation of multiple segments of text comprising one object's long remarks.
long_remark
varchar(600)
The long remarks text associated with the object.
remark_language
integer
Currently unused.
ii_objects Catalog
The ii_objects catalog contains a row for every user interface object in the database. This catalog stores basic information about each object, such as name, owner, object ID, object class, and creation date.
Objects in this table often have additional information represented in rows of one or more other user interface catalogs; for example, form objects are also represented by rows in ii_forms, ii_fields, and ii_trim. In all cases, the object ID is the key column that is used to join information from multiple catalogs about a single object.
The ii_objects catalog is a btree table, keyed on the object_class, object_owner, and object_name columns. The ii_objects catalog has a secondary index, btree unique, keyed on the object_id column:
Column Name
Data Type
Description
object_id
integer
The object identifier, unique among user interface objects in the database.
object_class
integer
The object's class. Tells what type of object this is (form, report, and so on). For object class definitions, see Object Classes in the ii_objects Catalog.
object_name
varchar(32)
The name of the object.
object_owner
varchar(32)
The object owner's user name.
object_env
integer
Currently unused.
is_current
smallint
Currently unused.
short_remark
varchar(60)
A short descriptive remark associated with the object.
object_language
smallint
Currently unused.
create_date
char(25)
The time and date when the object was initially created.
alter_date
char(25)
The time and date when the object, or associated information, was most recently altered or saved.
alter_count
integer
A count of the number of times this object has been altered or saved.
last_altered_by
varchar(32)
The name of the user who last altered or saved this object.
Object Classes in the ii_objects Catalog
Object class is a column in the ii_objects catalog. Each object class is as follows:
