Hi Team, 

I am trying to alter a SQLQuery as follows:

Patch Endpoint: https://<ip server>:50000/b1s/v1/SQLQueries('AquisitionCosts')

Body:

{
 "SqlCode": "AquisitionCosts",
 "SqlName": "AquisitionCosts",
 "SqlText": "select ItemCode, sum(APC) as APC from (select distinct ItemCode, TransType, APC from FIX1 where TransType in (110, 115, 120)) as v1 where ItemCode like '_________________' group by ItemCode"
}
 
The SQL is working fine but I do receive a proxy error howver:
<html>

<head>
    <title>502 Proxy Error</title>
</head>
<body>
    <h1>Proxy Error</h1>
    <p>The proxy server received an invalid
        response from an upstream server.<br />
The proxy server could not handle the request
    <p>Reason: <strong>Error reading from remote server</strong></p>
    </p>
</body>
</html>

Hi 

To resolve the 502 Proxy Error:

Validate SQL Query: Ensure the SQL query works directly in the database.
Check Endpoint and Authentication: Confirm the URL and authentication details are correct.
Review Server and Proxy Settings: Check server and proxy configurations for issues.
Simplify Query: Test with a simpler query to see if the issue is related to query complexity.

sample example:

Testing with Simplified Query:
SELECT ItemCode, COUNT(*) FROM FIX1 WHERE TransType IN (110, 115, 120) GROUP BY ItemCode

Example of Modified Request Body: Here's how you can format a simplified request body for testing:
{
"SqlCode": "AquisitionCosts",
"SqlName": "AquisitionCosts",
"SqlText": "SELECT ItemCode, SUM(APC) AS APC FROM (SELECT DISTINCT ItemCode, TransType, APC FROM FIX1 WHERE TransType IN (110, 115, 120)) AS v1 GROUP BY ItemCode"
}
By following these steps, you should be able to identify the root cause of the 502 Proxy Error and take appropriate actions to resolve it.

Hi Umasaral. Thanks for your reply! I did all of your suggestions: The query runs ok directly in the database and when I try to update with a simple query, I do notreceive the proxy error and the query saves correctly

It seems that the servicelayer is not accepting a query with a subquery. For example the query "select ItemCode from (select * from FIX1) v1" gives me an error as well while the query is correct
