title: Duplicate row detected during DML action - Snowflake - Talend
body: <p>I want to load data into Snowflake with Talend. I used tSnowflakeOutput with Upsert option because I want to insert data if not exists in Snowflake, or update rows if it exists. I used the primary key to identify the rows that already exist.</p>
  
  <p>When I run my job, I have the following error: </p>
  
  <blockquote>
    <p>Duplicate row detected during DML action</p>
  </blockquote>
  
  <p>I am aware that the problem is due to a line that exists in Snowflake, I want to update the line but all I've got is this error.
  do you have an idea why? </p>
  
  <p>Please help :) </p>
