Options to configure rule type SingleColumnChange. The rule is used to change the properties of a column. The rule filter field can refer to one entity. The rule scope can be one of: Column. When using this rule, if a field is not specified than the destination column’s configuration will be the same as the one in the source column..

This type is not used in any activity, and only used as part of another schema.

Fields

array: Option<bool>

Optional. Is the column of array type.

array_length: Option<i32>

Optional. The length of the array, only relevant if the column type is an array.

auto_generated: Option<bool>

Optional. Is the column auto-generated/identity.

charset: Option<String>

Optional. Charset override - instead of table level charset.

collation: Option<String>

Optional. Collation override - instead of table level collation.

comment: Option<String>

Optional. Comment associated with the column.

custom_features: Option<HashMap<String, Value>>

Optional. Custom engine specific features.

data_type: Option<String>

Optional. Column data type name.

fractional_seconds_precision: Option<i32>

Optional. Column fractional seconds precision - e.g. 2 as in timestamp (2) - when relevant.

length: Option<i64>

Optional. Column length - e.g. 50 as in varchar (50) - when relevant.

nullable: Option<bool>

Optional. Is the column nullable.

precision: Option<i32>

Optional. Column precision - e.g. 8 as in double (8,2) - when relevant.

scale: Option<i32>

Optional. Column scale - e.g. 2 as in double (8,2) - when relevant.

set_values: Option<Vec<String>>

Optional. Specifies the list of values allowed in the column.

udt: Option<bool>

Optional. Is the column a UDT (User-defined Type).
