Data Intelligence: Dynamic SQL functions are not working in open connector SQL Operator

Posted on Jul 17, 2020 at 01:23 PM 115 Views Last edit Jul 17, 2020 at 01:24 PM 2 rev.

Hi Team,

I am trying to use Open connector SQL Consumer Operator in a graph to fetch incidents from ServiceNOW.

But I am not able to use dynamic SQL functions in WHERE clause. (WHERE "sys_updated_on" > '2020-07-16' --> is working fine)

Below is the SQL I am using.

SELECT "number", "opened_at", "closed_at", "assigned_to"
FROM incidents 
WHERE "sys_updated_on" >= add_days(current_date,-1)

Below is the error:

Group messages: 
Group: default; Messages: Graph failure: flowagenttableproducer1 failed with the following error: HTTP 400 Bad Request: {"requestId":"5f0f259ae4b0d503xxxxxxxx","message":"com.cloudelements.executor.service.query.expression.BaseFieldNameExpression cannot be cast to com.cloudelements.executor.service.query.expression.BaseFieldValueExpression"} 
Pod is failed. Container is terminated. Error. ExitCode=1. Signal=0

Can someone help me to solve this error.

Thanks in advance.

Regards,

Suchen.

    An update to this issue. We managed to fix it by taking the following steps

    - creating a new table in HANA with a query (make it dynamic by including the changes in a procedure)

    - initiate the graph with "HANA Table Consumer" operator, connecting it to a flowagent CSV producer, to a toString converter, to a Python operator that formats the query string correctly, to the Open Connectors SQL Consumer operator, to a wiretap and to a Flowagent Table Producer.

    Ok, then it is hard to predict here.
    It can be a bug in SAP Data Intelligence directly. Not everything is tested beforehand

    Best Regards Roland
