Class MultiColumnDatatypeChange (1.9.4)

MultiColumnDatatypeChange(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Options to configure rule type MultiColumnDatatypeChange. The rule is used to change the data type and associated properties of multiple columns at once.

The rule filter field can refer to one or more entities.

The rule scope can be one of:Column.

This rule requires additional filters to be specified beyond the basic rule filter field, which is the source data type, but the rule supports additional filtering capabilities such as the minimum and maximum field length. All additional filters which are specified are required to be met in order for the rule to be applied (logical AND between the fields).

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
