Extract Query Results

{ extractQueryResult }

Runs a content item and extracts the raw query result data into the specified format (CSV, JSON, XML).

Method

Input Parameters

Output Response

Notes

Queries are extracted in flattened tabular format – and do not represent the cartesian of the data. Multiple queries can be extracted into XML or JSON formats only. The CSV option is only available for single queries running from Discovery content.

Examples

Running Queries and Slicers programmatically (JavaScript):

This example demonstrates how to run queries and slicers (parameters) programmatically to extract results.

The example uses API authentication driven from JavaScript. See Authentication APIs for alternatives.

// URL of the Pyramid installation and the path to the API 2.0 REST methods
var pyramidURL = "http://mysite.com/api2/";


// step 1: authenticate admin account and get token
// NOTE: callApi method is a generic REST method shown below.
let token = callApi("auth/authenticateUser",{
	"data":{
		"userName":"adminUser",
		"password":"abc123!"
	}
},false);


//step 2: find a parameter definition called "param x". Parameters are saved items to drive slicers
let calculation = callApi("content/findContentItem",{
	"searchParams": {
		"searchString": "param x",
		"filterTypes": [2],
		"searchMatchType": 2,
		"searchRootFolderType":0
	},
	"auth": token // admin token generated above
});

let paramId = calculation.data[0].id;

//step 3: get the parameter's elements
let parameterElements = callApi("query/getParameterElements",{
   "parameterId": paramId,
   "auth": token
});

let members = parameterElements.data.members // list for members
console.log(members);

//step 4: find a data discovery called "report x"
let dataDiscovery = callApi("content/findContentItem",{
	"searchParams": {
		"searchString": "report x",
		"filterTypes": [3],
		"searchMatchType": 2,
		"searchRootFolderType":0
	},
	"auth": token // admin token generated above
});


let reportId = dataDiscovery.data[0].id;

//step 5: extract the report results as JSON that have been filtered by the first member of the parameter found in step 3
let queryResult = callApi("query/extractQueryResult",{
   "data": {
      "itemId":reportId,
      "exportType":0, //JSON
      "exportOptions": {},
      "externalParameters": {
        "reportFilters" : [
         {
         "value": members[0].uniqueName
         }
        ]
      }
   },
   "auth": token
});

console.log(JSON.parse(queryResult.data));


// ##### optional generic logging method for debugging ##############
function log(msg){
	document.write(msg);
	console.log(msg);
}

// ##### generic REST API calling method ##############
function callApi(path,data,parseResult=true){
	var xhttp = new XMLHttpRequest();
	xhttp.open("POST", pyramidURL+path, false);
	xhttp.send(JSON.stringify(data));
	if(parseResult){
		return JSON.parse(xhttp.responseText);
	}else{
		return xhttp.responseText;
	}
}

		

User Client/API Authentication (C#):

This example demonstrates how to authenticate users with Windows Authentication and run a query programmatically.
