A list of column name mappings for MongoDB's built-in columns.

Data Type

string

Default Value

""

Remarks

This property takes a comma-separated list of MongoDB column names for built-in columns and maps them to new names.

The remappable built-in columns are "_index" and "P_id".

For example:

_index=BuiltInIndex,P_id=Parent_Id

Remapping these columns is particularly useful for resolving "column names must be unique" errors that can arise when the add-in finds additional columns named "_index" or "P_id" other than the built-in columns.
