Search Results subject_name

Overview

ENG_SUBJECTS_VL is a seeded, language-enabled (VL) view owned by the APPS schema in Oracle E-Business Suite 12.1.1 and 12.2.2. It belongs to the Engineering (ENG) product family and exposes a translated, read-only projection of engineering subject reference data. In the Oracle EBS object model, a view whose name ends in _VL typically denotes a "translated" view that resolves a base table plus its translation table, filtering rows according to the session's language setting. ENG_SUBJECTS_VL performs exactly this role: it joins the base table ENG_SUBJECTS_B with its translation table ENG_SUBJECTS_TL and returns only the translation row matching the current user's language environment.

The view is validated and documented in the EBS Technical Reference Manual (ETRM) for 12.2.2 with owner APPS. It presents a single, user-facing semantic layer over the two physical tables that ETRM cites as its referenced base objects: the ENG_SUBJECTS_B synonym and the ENG_SUBJECTS_TL synonym. Because it centralizes language resolution, ENG_SUBJECTS_VL is the object that reports, forms, and integrations should query rather than accessing the underlying descriptive tables separately. The search term "subject_name" maps directly to the primary descriptive attribute returned by this view.

Underlying Base Objects

The reported view text defines the view as follows:

SELECT B.SUBJECT_ID, T.SUBJECT_NAME
FROM   ENG_SUBJECTS_B B, ENG_SUBJECTS_TL T
WHERE  B.SUBJECT_ID = T.SUBJECT_ID
AND    T.LANGUAGE = USERENV('LANG')

Two documented base objects are referenced, both exposed in the APPS schema as synonyms:

• ENG_SUBJECTS_B — the base (non-translated) table holding the language-independent key attribute, SUBJECT_ID.
• ENG_SUBJECTS_TL — the translation table holding SUBJECT_ID, LANGUAGE, and the translatable descriptive column SUBJECT_NAME.

The join is an equi-join on SUBJECT_ID, and the WHERE clause restricts output to rows where T.LANGUAGE equals USERENV('LANG'), i.e. the language of the current database session. This pattern is the standard Oracle multilingual ("MLS") design; it ensures a single row is returned per subject for the active language, while preserving the same SUBJECT_ID across all language variants.

Key Columns

• SUBJECT_ID — the primary identifier for an engineering subject. It is sourced from ENG_SUBJECTS_B and is unique per subject. Because it is language-independent, it is the correct foreign-key value for joins to engineering objects or classifications that reference a subject.
• SUBJECT_NAME — the translatable display name of the subject, sourced from ENG_SUBJECTS_TL. Its value depends on USERENV('LANG'); the same SUBJECT_ID may resolve to different names depending on the session language.

Only these two columns are exposed. Any additional descriptive or audit attributes present on the physical tables are intentionally hidden by the view definition.

Common Use Cases and Queries

ENG_SUBJECTS_VL is principally used to obtain the localized name of an engineering subject, either for reporting or for populating list-of-values and lookup fields. The most direct query is:

SELECT SUBJECT_ID, SUBJECT_NAME
FROM   APPS.ENG_SUBJECTS_VL
ORDER BY SUBJECT_NAME;

To resolve the name for a specific subject:

SELECT SUBJECT_NAME
FROM   APPS.ENG_SUBJECTS_VL
WHERE  SUBJECT_ID = :p_subject_id;

Because the view already resolves language, a join to engineering data needs only the subject key:

SELECT e.object_name, s.SUBJECT_NAME
FROM   APPS.ENG_SUBJECTS_VL s, some_eng_table e
WHERE  e.subject_id = s.SUBJECT_ID;

Typical scenarios include engineering change order reports requiring a localized subject label, custom concurrent programs sourcing subject values for parameters, and integration extracts that must present subject names in the operator's language. In all such cases, querying ENG_SUBJECTS_VL is preferable to querying ENG_SUBJECTS_TL directly, because the view enforces the USERENV('LANG') filter and thereby prevents duplicate or non-localized results.
