Ingres

Ingres tables and views can be documented in Predict with file objects of type JT and JV respectively. These file objects can be used to generate DDMs or CREATE TABLE/VIEW statements.

This document covers the following topics:

Naming Conventions

The following naming conventions apply to files documenting Ingres tables and views.

Upper / lower case

If the Predict parameter General Defaults > Miscellaneous > Upper/lower case / Object ID is set to L, the following attributes of Ingres objects are stored in upper and lower case as entered:

  • File ID (object IDs containing lower case letters are not recommended)

  • DV field expressions

  • SQL verifications

  • Check expressions

  • Constraint names

See also section Defaults in the Predict Administration documentation.

Length

  • Table/View names for Ingres objects can have up to 24 characters.

  • A fully qualified ID (Creator + Hyphen + Table/View name) may not exceed 32 characters.

Permitted characters

See overview of permitted characters in Naming Conventions.

Parameters not listed below are described in other sections of this documentation: Parameters common to all object types, for example Keys, are described under Global Attributes. Parameters common to all file types, for example Literal name, are described under Common File Attributes. See also Common Parameters for SQL File Types.

Parameters
File ID

ID of the Predict object documenting the Ingres table.

See Naming Conventions for Ingres objects.

Contained in DA

ID of the database object containing the file.

To generate a DDM from files of type Ingres table, the file must be linked to a database of type Ingres Handler.

Journaling
Y The clause WITH JOURNALING is entered in the CREATE statement.
N The clause WITH NO JOURNALING is entered in the CREATE statement.
Duplicated
Y The clause WITH DUPLICATES is entered in the CREATE statement.
N The clause WITH NO DUPLICATES is entered in the CREATE statement.

Parameters
File ID

ID of the Predict object documenting the Ingres view.
