How to use Joins in queries in js files

Hi there,

 

I am trying to query data from javascript like below:

 

var query = NLWS.xtkQueryDef.create(
  {queryDef: {schema: "nms:recipient", operation: "select", 
    select: {
        node: [{expr: "@id"},
               {expr: "@label"},
               {expr: "@internalName"}] 
    }, 
    where: {
      condition: [{expr: "@id='16'"}]
    }
  }})

 

So for the above query, if I have another table which is nms:userEmail. And I want to inner join this table with the current one(which is the one that shows above in the js code(nms:recipient)), and get the joined table. How can I do that here? What the query should be like?

 

Thank you!

Hi,

 

Is the join defined in the schema already? In that case you should be able to reference attributes of the linked schema in the query, either in selected nodes or conditions:

 

var query = NLWS.xtkQueryDef.create(
  {queryDef: {schema: "nms:recipient", operation: "select", 
    select: {
        node: [{expr: "@id"},
               {expr: "@label"},
               {expr: "@internalName"},
               {expr: "linkToOtherResource/@linkedAttribute"}] 
    }, 
    where: {
      condition: [{expr: "@id='16'"}]
    }
  }})

 

Regards

    Hi, jonasn, thx so much for replying me!, I have added sth like "expr: "emailInfo/@email]", and the externalJoin is in my schema. But I got the error which says :"The node of path '/' is not stored as an independent SQL field, UNable to use it as a filtering criteria in a query". Do you know how this error comes?
