Reference documentation and code samples for the Cloud Database Migration Service V1 API class Google::Cloud::CloudDMS::V1::MultiColumnDatatypeChange.
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).
(::Integer) — Optional. Column fractional seconds precision - used only for timestamp
based datatypes - if not specified and relevant uses the source column
fractional seconds precision.
value (::Integer) — Optional. Column fractional seconds precision - used only for timestamp
