Data merge4/3/2023 ![]() ![]() You can personalize or customize any element of a print-based InDesign layout or control changes within still or moving artwork to reach one or millions of recipients. With XMPie you can do everything that is possible with the in-built Adobe tools, and take it to a much higher level. But what if you need more options and flexibility, and you want to spend more time focusing on the actual design, instead of getting swamped by the data merge process? XMPie Video Personalization Service (XVS)ĭata Merge is an effective tactic to make your communications stand out from the competition, and Adobe InDesign and Illustrator include a built-in feature to help with this task.How field names appear: For matching fields, the primary query's field names are used in the merged results, as shown above. ![]() In practical terms, here's why it matters which query is the primary query: If you aren't familiar with the idea of a left join, no worries. The results of the added query are combined with the results of the primary query as if they are being left joined into the primary query. But, for those who are familiar with SQL joins, the Merged Results feature combines the results of multiple Explores in a similar way as would a left join. Merged results do not perform an actual SQL join. This means that if the primary query and an added query use different names for a matching dimension, only the primary query's dimension name will be displayed in the results. You can set an added query as the primary query by switching the primary query.īelow is an example of a set of queries and their merged results:Īll of the primary query's fields are displayed in the merged results, using the primary query's names for the fields. So, whenever you add a query, you need to include a dimension that can be matched to a dimension in the primary query. This is an important concept because when Looker matches the data to create the merged results, it matches each added query to the primary query (not to any other added query). ![]() If you include queries that return more than 5,000 rows of data, only the first 5,000 rows returned are included in the merged results.īy default, that first query is considered the primary query. The Merged Results feature has a limit of 5,000 rows of data for each of the merged queries. When you merge queries, you start out by creating a single query from a single Explore, and then you combine other queries with that first query. You can use Merged Results as a proof of concept to further develop and define your LookML projects and models. ![]() In these cases, Merged Results lets you combine results from different Explores (even from different models or projects) to create data tables on which to Explore and create visualizations. However, there may be times when your Looker developers haven't created the relationships you need or have encountered technical limitations. Because of this, it is best to use a single Explore to examine your data. View the Optimize Looker performance Best Practices page for more information about optimizing Looker performance.Įxplores in Looker are designed by your Looker developers to combine the data from your database tables in the most effective way by using defined relationships between data fields and tables. Best practice is to define functions and logic in LookML instead, which generates SQL that is processed by your database. Merged Results is a post-query processing feature that, if not used thoughtfully, can overtax Looker instance resources and cause your Looker instance to respond more slowly for all users.
