Limit rows while fetching records using QueryDatabase Table using NiFi












0














I am trying to use QueryDatabase processor using Apache NiFi
Is there any way I can limit the records something like : “select * from table limit 100”



Any other processor in NiFi which supports this operation?

          Use ExecuteSQL processor for this case.




          • Configure/Enable DBCP connection pool



          • In SQL select query property value keep your select query



            select * from table limit 100
            enter image description here




          Now processor runs the configured sql select query and outputs the results of the query as a flowfile in AVRO format

          • Thanks a lot Shu... it worked. I have a Question though I cannot see these many options in my ExecuteSql processor. I have 1.7.0 version, is it something new on 1.8.0?
