table_name

char(256)

create_date

char(25)

The object's creation date. Blank if unknown.

alter_date

char(25)

The last time this table was altered. This date is updated whenever the logical structure of the table changes, either through changes to the columns in the table or changes to the primary key. Physical changes to the table, such as changes to data, secondary indexes, or physical keys, do not change this date. Blank if unknown.

table_type

char(1)

Type of query object:

T = Table
V = View
I = Index

Further information about tables can be found in iiphysical_tables. Further information about views can be found in iiviews.

table_subtype

char(1)

Specifies the type of table or view. Possible values are:

N (native) - For standard Ingres databases.

L (links) - For Ingres Star.

I (imported tables) - For Enterprise Access products.

(blank) - If unknown

table_version

char(5)

Version of the object. Enables the user interfaces to determine where additional information about this particular object is stored. This reflects the database type, as well as the version of an object within a given database. For Ingres tables, the value for this field is II2.5.

system_use

char(1)

Contains S if the object is a system object, U if user object, or blank if unknown.

Used by utilities to determine which tables need reloading. If the value is unknown, the utilities use the naming convention of “ii” for tables to distinguish between system and user catalogs. In addition, any table beginning with ii_ is assumed to be a user interface object, rather than a DBMS system object. The standard system catalogs themselves must be included in the iitables catalog and are considered system tables.

table_indexes

char(1)

Contains Y if this object has entries in the iiindexes table that refer to this as a base table, or N if this object does not have entries. If the field is blank, then query iiindexes on the base_table column.

This field is used for optimization of Ingres databases.

is_readonly

char(1)

Contains one of these values:

N - If updates are physically allowed

Y - If no updates are allowed

Blank - If unknown

Used for tables that are defined to the Enterprise Access product only for retrieval, such as tables in hierarchical database systems.

If this field is set to Y, then no updates will work, independent of what permissions might be set. If it is set to N, updates may be allowed, depending on whether the permissions allow it.

Y if concurrent access is allowed.

num_rows

integer

The estimated number of rows in the table. Set to -1 if unknown.

storage_structure

char(16)

key_is_compressed

char(1)

Contains Y if the table uses key compression, N if no key compression, or blank if unknown.

duplicate_rows

char(1)

D - If the table allows duplicate rows.

U - If the table does not allow duplicate rows.

Blank - If unknown.

The table storage structure (unique or non-unique keys) can override this setting.

unique_rule

char(1)

D - Indicates that duplicate physical storage structure keys are allowed. (A unique alternate key may exist in iialt_columns and any storage structure keys may be listed in iicolumns.)

U - If the object is an Ingres object, indicates that the object has unique storage structure key. If the object is not an Ingres object, then it indicates that the object has a unique key, described in either iicolumns or iialt_columns.

Blank - If uniqueness is unknown or does not apply.

number_pages

integer

The estimated number of physical pages in the table. Set to -1 if unknown.

overflow_pages

integer

The estimated number of overflow pages in the table. Set to -1 if unknown.

smallint

For a partitioned table, this is the number of physical partitions. For a physical partition, this is the partition number.

partition_dimensions

smallint

For a partitioned table, this is the number of dimensions (partitioning levels) in the table's partitioning scheme. In all other cases, this is zero.

row_width

integer

The size, in bytes, of the uncompressed binary value for a row of this query object. For encrypted tables, the width of the encrypted row.

unique_scope

char(8)

R if this object is row-level, S if statement-level, blank if not applicable.

allocation_size

integer

The allocation size, in pages. Set to -1 if unknown.

extend_size

integer
