Update the Connection for a Data Target
{ updateTargetNodeConnection }
Updates the details of a specific data flow target node.
Method
- Enterprise Admin
Input Parameters
Name
connectionObject
Object Type
Description
Use this object to modify the data target server and/or the database in a data flow.
Output Response
Successful Result Code
200
Response Type
Description of Response Type
Generic API response object with success or failure flag and related messages.
Notes
Use this function to either correct or adjust the data target node found in a data flow - using either the server ID, database name or both.This function does not operate on materialized models, since the target is inherent in the materialization itself.
Examples
This example demonstrates how to update data flow objects and execute flows in Pyramid.
The example uses API authentication driven from JavaScript. See Authentication APIs for alternatives.

Code Snippets
Use the Authentication API methods to generate an access 'key' or 'token' for use in code as shown below.
curl -X POST \
-H "paToken: [[apiKey]]" \
-H "Accept: application/json,application/json;charset=utf-8,text/plain,text/plain;charset=utf-8" \
-H "Content-Type: application/json" \
"http://Your.Server.URL/API3/dataSources/updateTargetNodeConnection" \
-d '{
"itemId" : "itemId",
"databaseName" : "databaseName",
"dataFlowNodeId" : "dataFlowNodeId",
"useExistingDatabase" : true,
"serverId" : "serverId"
}'
