iitables Catalog
The iitables catalog contains an entry for each table, view, or index in the database.
Column Name
Data Type

table_name
char(256)

create_date
char(25)
The creation date of the object
Blank if unknown
alter_date
char(25)
The last time this table was altered.
Updated when the structure of the table changes through changes to the columns in the table or 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)

T if table
V if view
I if index
P if physical partition of a partitioned table
Further information about views can be found in iiviews.
table_subtype
char(1)
Specifies the type of table or view.
N if native for standard Ingres databases
L if links for Star
I if imported tables for Enterprise Access
Blank if unknown
table_version
varchar(11)
Version of the object; enables the Ingres tools to determine where additional information about this particular object is stored. This reflects the database type, as well as the version of an object in a given database. For Ingres tables, the value for this field is II9.0.
system_use
char(1)
S if the object is a system object
U if user object
G if generated by the system for the user
Blank if unknown
tups_per_page
integer

keys_per_leaf
integer
Maximum keys per leaf for BTREE tables
The following columns have values only if the table_type is T, I, or P. Enterprise Access products that do not supply this information:
Numeric columns are set to -1
Character columns are set to blank.
Column Name

If Y updates cannot occur, irrespective of the permissions set
If N updates are allowed depending on the permissions setting
concurrent_access
char(1)
Y if concurrent access is allowed
num_rows
integer
The estimated number of rows in the table
-1 if unknown
If value is for a partitioned table, this is the total for all partitions
storage_structure
char(16)
The storage structure of the table:
HEAP
HASH
BTREE
ISAM
is_compressed
char(1)
Y if the table is compressed
N if the table is uncompressed
Blank if unknown
key_is_compressed
char(1)
Y if the table uses key compression
N if no key compression
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 vs. non-unique keys) can override this setting.
unique_rule
char(1)
D if duplicate keys are allowed. (A unique alternate key exists in iialt_columns and any storage structure keys are listed in iicolumns.)
U if the object is an Ingres object, indicates that the object has unique storage structure keys.
If the object is not an Ingres object, 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 used pages in the table
-1 if unknown
If the value is for a partitioned table, this is the total for all partitions.
overflow_pages
integer
The estimated number of overflow pages in the table
-1 if unknown
partition_dimensions
smalliint
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.
phys_partitions
smallint
For a partitioned table, this is the number of physical partitions.
For a physical partition, this is the partition number
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.
The following columns are used by the DBMS Server, except for those preceded by an asterisk (*).
Columns preceded by an asterisk (*) have values only if table_type is T or I.
