# LookupTableRowType (Complex Type)

### Namespace: http://midpoint.evolveum.com/xml/ns/public/common/common-3

Data structure that represents entire content of the lookup table, organized into table rows. The delta semantics has a slightly different meaning for the lookup tables. Each key must be unique and the key functions as an implicit identifier. E.g. adding a new row with a key that does not exist yet will insert a new row. Adding a new row with key that already exists will overwrite existing row. Replace operation on this property will efficiently clear the entire table and replace it with a new data. We do not recommend using this operation as it may be very inefficient. Add and delete operations are expected during normal operation.

    Timestamp of the last change of the row. This is automatically maintained by the repository. It is updated every time the row is created or updated. This row is intended to act as a "token" if the lookup table needs to be synchronized with external resource.
