Is it possible to query a View in a Calculated Field?

[JayDub]

I have a DataForm with a calculated field. In the calculated field, I would like to look up and Sum matching records in a View. I know that you can query a Table in a calculated field, and I have done this successfully. However, the value that I need is currently in a View. When I create the query in the calculated field using the name of a View, I get an Invalid Formula error. I am trying to use a View instead of a table because there is not a direct relationship between the current table the DataForm is based on and the Table the value I need to Sum is in. I have to relate both tables via a third 'join' table to get it

If, in fact, you can't query a  View in a calculated field, is it possible to create a query in a Calculated field that joins multiple tables together (I'm guessing no - all of the examples of queries in calculated fields I've seen are simple SELECTs on one table.) Thanks for all input!

Hi @JayDub,

If you want to select data from a View, you should add prefix _v_ to the View name. More details can be found here: https://howto.caspio.com/datapages/reports/advanced-reporting/calculations-in-forms-and-reports/

You can join as many tables in the Select statement in the Calculated field as needed. The syntax is the same as in the SQL. However, it will be easier to refer to the View.

Thanks so much @Alison! That worked perfectly.

If you feel a bit more adventurus, you may want to recreate the view itself on the calculated value using a join sql formula: https://www.w3schools.com/sql/sql_join.asp

I tried it and no such luck. My view name is vwAgentProperty

SELECT tblAgent.AgentFullName
FROM prefix_v_vwAgentProperty
WHERE tblAgent.PropertyID=[@field:PropertyID]

 

ALSO TRIED

SELECT tblAgent.AgentFullName
FROM _v_vwAgentProperty
WHERE tblAgent.PropertyID=[@field:PropertyID]

Hi,  @Hiperf. Make sure that you are using the same column name as from the Views. Try using:

SELECT tblAgent_AgentFullName
FROM _v_vwAgentProperty
WHERE tblAgent_PropertyID = [@field:PropertyID]
