IS_HARDENED()

This function evaluates to a single character and is applied to columns that contain property values that can be hardened.

erwin DM r8 only allows hardening of name values, so this function only has meaning when applied to the NAME column and the PHYSICAL_NAME column of the ATTRIBUTE, DEFAULT, DOMAIN, ENTITY, KEY_GROUP, RELATIONSHIP, and VALIDATION_RULE tables. Future releases of erwin DM may extend hardening to more property types.

It will evaluate to T if the value in the property has been hardened, otherwise, it will evaluate to F.

For example, suppose you use the Name Hardening Wizard to harden the Physical_Name of all Attribute objects in the eMovies.ERWIN model. The following query shows the results of the IS_HARDENED() function:

SELECT NAME, PHYSICAL_NAME, TRAN(PHYSICAL_NAME),

IS_HARDENED(NAME) AS 'Logical', IS_HARDENED(PHYSICAL_NAME) AS 'Physical'

FROM ATTRIBUTE

WHERE PHYSICAL_NAME IS NOT NULL

ORDER BY 1

The row restriction is to filter out view columns, which are not type-split from table columns as of erwin DM r8.
