Format
SHOW FIELD [ qualifier ] ... [ field-name ] ,...
[ FROM DATABASE database-name ]
1 – Parameters
1.1 – field-name
Specifies the field element whose properties you are displaying.
When you use the FROM DATABASE clause, specify only one field
name for each SHOW FIELD command.
Specify an asterisk (*) wildcard character for the entire field-
name parameter only. If you use a wildcard character as part of
the field-name parameter, an error occurs.
1.2 – database-name
Specifies the Oracle Rdb database that contains the field. CDO
requires this parameter for fields from an Oracle Rdb database.
CDO accepts wildcard characters in the database name.
2 – Qualifiers
2.1 /ALL
Displays system-specified properties, such as time of creation,
and user-specified properties, such as description, for the field
name and for all children.
2.2 /AUDIT
Displays history list entries for the field name. The /AUDIT=ALL
qualifier displays the history list entries for the field name
and for all children. Do not use this qualifier if the field name
you specify is from an Oracle Rdb database definition.
2.3 /BRIEF_(default)
Displays user-specified properties for the field name, and
provides the names of direct children.
2.4 /FULL
Displays user-specified properties for the field name and for all
children.
2.5 /SYSTEM
Format options:
/SYSTEM
/NOSYSTEM (default)
Specifies whether CDO displays Oracle Rdb system relations.
2.6 /RDB_METADATA
Format options:
/RDB_METADATA
/NORDB_METADATA (default)
Specifies whether CDO displays Oracle Rdb system relations. This
qualifier is synonymous with the /SYSTEM qualifier.
3 – Description
The SHOW FIELD command displays a complete or partial list of
properties for the field names you specify, provided you have
read privileges.
If you do not specify a full path name (or the FROM DATABASE
clause) for the field name, CDO searches your current default
directory for the field name. If you do not specify a field name,
CDO displays the properties of all field names in your default
directory.
If you do not specify a version number for a field name, CDO
displays the properties of the highest visible version.
NOTE
If you make incompatible changes to the CDD$DATA_ELEMENT
type, supplied by Oracle CDD/Repository, the SHOW FIELD
command may not display those properties whose data types
you have modified.
If a field has character set attributes, you can display them
using the SHOW and EXTRACT commands; in addition, you can use
the SHOW command to display size information of a field in both
character-based size and octet-based size. See the descriptions
of SET CHARACTER_SET command and the DATATYPE_Field_Property help
topic found under the fld-properties topic for
more information.
4 – Examples
1.CDO> SHOW FIELD CORPORATE_ZIPCODE FROM DATABASE DEPT3

SHOW FIELD command displays default BRIEF information. This
information includes the user-specified properties for the
CORPORATE_ZIPCODE field name and the names of direct children.
2.CDO> DEFINE FIELD FULL_NAME
cont> DATATYPE TEXT CHARACTER_SET KANJI
cont> SIZE 2 CHARACTERS.
CDO> SHOW FIELD FULL_NAME
Definition of field FULL_NAME
| Datatype text size is 2 characters (4 Octets)
| Character_set KANJI
This example defines and shows the field FULL_NAME.
