Examples of GBQ queries using Analytics and Reporting


Can you give me some examples of GBQ queries to access information using Reporting and Analytics tables and views?


Each row of the table represents a single entity of that given type. Since each entity has at least one but most likely multiple crosswalks, each table has a crosswalk column. In Reltio each crosswalk is considered as an object. Therefore, the crosswalk object is mapped to STRUCT in Reltio Analytics. Furthermore, as the crosswalks can be more than one for each entity or each row in our Reltio Analytics table, the column is also REPEATED.

The array of crosswalk objects in Reltio is mapped to REPEATED STRUCT in Reltio Analytics. The STRUCT has the following properties of a crosswalk as sub-columns:
  • values
  • attributes
  • uri
  • updateDate
  • deleteDate
  • reltioLoadDate
  • source
  • sourceTable
  • refEntityOrRelationId
  • createDate

How to Unnest Columns

Unnesting columns in Reltio Analytics is the process of flattening a list of values in a column. This is a fairly simple task but has a great influence on performance. Therefore you must perform this task with caution. The following is an example of unnesting:
  cw AS Crosswalk
FROM `<dataset_id>.entity_Individual_source`,
UNNEST (crosswalks) AS cw
You are recommended to give an alias of your column as it helps you to avoid duplicate column errors. You can also unnest multiple columns at once as shown below.
  cw AS Crosswalk,
  tg AS Tag
FROM `<dataset_id>.entity_Individual_source`,
UNNEST (crosswalks) AS cw,
UNNEST (tags) as tg
You can also partially select sub-columns if your nested column is a STRUCT as shown below.
  cw.Uri AS CrosswalkUri,
  cw.Source AS CrosswalkSource,
  tg AS Tag
FROM `<dataset_id>.entity_Individual_source`,
UNNEST (crosswalks) AS cw,
UNNEST (tags) as tg


Get the number of entities for a particular entity type

SELECT count(distinct Id) 
FROM `customer-facing-hipaa.views_riq_dw_<envirnoment>_<tenantID>.entity_<entityType>`,
UNNEST(crosswalks) as cw where deleted = false


How to gather crosswalk source system name and id for a specific entity

  Id as entity_Id,
  cwk.value as crosswalk_id,
SUBSTR(cwk.source, REGEXP_INSTR(cwk.source, '/', 1, 2)) as crosswalk_source,

`customer-facing.views_riq_<customer view>` as T,
UNNEST(T.crosswalks) AS cwk,
UNNEST(cwk.attributes) AS cwk_attr
--where id = '1AcTIHmT'
group by Id, crosswalk_id, crosswalk_source
order by crosswalk_source
limit 1000

Field definition

Each entity table also contains the following columns:

  • tags - The column holds the tags that can be attached to the entity REPEATED column.
  • createdTime - Timestamp of the entity created in the source system.
  • updatedTime - Timestamp of the last update of the entity in the source system.
  • startDate - The date when the entity was created in the Reltio system.
  • endDate - The date when the entity was soft-deleted (if deleted) in the Reltio system.
  • uri - The URI of the entity.
  • updatedBy - The ID of the person who made the last update.
  • type - The type of entity. Since one table holds information about one entity type, it is expected that all the records in the given table have the same value in this column.
  • createdBy - The creator of the entity.
  • eventTime - The time at which the event was logged.
  • versionTime - The version of objects in the data frame.
  • deleted - Boolean value indicates whether the entity is deleted or not.
  • deletedTime - Timestamp of the entity‚Äôs deletion in the source system.
  • id - The ID of the entity in the Reltio system.
  • insertedTime - Timestamp of an entity inserted in the GBQ streaming table. For GBQ batch table, insertedTime is equal to the updatedTime.
