1.2.2 Field Identifier

Mandatory.

The Identifier is a short, unique, name by which the field can be identified. While it is compulsory, it can be displayed, or not, on dialogs if specified in the LANSA Settings.
If it is not displayed, the system will automatically allocate a unique Identifier to new Fields.

Specify the Identifier of the field to be stored in the LANSA Repository.  Field Identifiers are not case sensitive. By default, field identifiers are often converted to upper case characters in LANSA.

Rules

• Must be a valid LANSA Object Name.

• Cannot be the same as the alias name or the alias for another field.

Warnings

• Avoid the use of field identifiers like SQLxxx, as this may cause problems when used in functions that use SQL (Structured Query Language) facilities. (i.e. Command SELECT_SQL.)

Platform Considerations

• IBM i: Use of identifiers of more than 6 characters in length is not recommended if you are writing your own RPG application programs. Refer to the RPG Programmer's Reference Guide.

Tips & Techniques

• Use alias name for COBOL or PL/1 long names.

• LANSA recommends a corporate data dictionary approach for creating fields in the LANSA Repository. Refer to Corporate Data Dictionary Concepts in the Developer Guide.
