GetCDMFieldValue¶

aggregating category: cdm-helpers no `||`

Returns the value of another field on the same CDM table.

Loads the value of the named field from the same CDM table as this rule. Establishes a dependency, forcing the referenced field to be calculated first. If multiple GetCDMFieldValue rules across the table create a circular reference, an error is thrown.

Parameters¶

1 — field Mandatory — accepts: field: The field on the same CDM table to load the value from, in :-notation.

Input type¶

Field reference (no value input).

Output type¶

The output type matches the referenced field's type.

Requires¶

No circular reference.
Field must be on the same table as the rule.
Only valid in field logic, not on a mapping rule.

Examples¶

Read the person_id field of the same CDM table

GetCDMFieldValue(:person_id)
