Detailed Description

A set of output parameters for updateRecordsRaw(const RawUpdateRecordsRequest&) const.

Runs multiple predicate-based updates in a single call. With the list of given expressions, any matching record's column values will be updated as provided in newValuesMaps. There is also an optional 'upsert' capability where if a particular predicate doesn't match any existing record, then a new record can be inserted.

Note that this operation can only be run on an original table and not on a collection or a result view.

This operation can update primary key values. By default only 'pure primary key' predicates are allowed when updating primary key values. If the primary key for a table is the column 'attr1', then the operation will only accept predicates of the form: "attr1 == 'foo'" if the attr1 column is being updated. For a composite primary key (e.g. columns 'attr1' and 'attr2') then this operation will only accept predicates of the form: "(attr1 == 'foo') and (attr2 == 'bar')". Meaning, all primary key columns must appear in an equality predicate in the expressions. Furthermore each 'pure primary key' predicate must be unique within a given request. These restrictions can be removed by utilizing some available options through options.
