Logging sql query usage and time of execution.

Explorer

Here is my current Nifi workflow. 

1. Getfile bring the CSV file into the flow 

2. As you can see, they are saved in separated tables named 'cattle_auction_data' and 'cattle_auction_invalid_data' after going through UpdateRecord processor to add a column with the original filename.

 

Here is what I am trying to do. The Query Record processor performs two sql queries, 'valid' and 'invalid'

I would like to log the sql queries and their time of execution, make them go through updaterecord processor to add a column with the filename and save them into the table named 'validation-log' . that the final product looks like below 

 

filename  |                                  sql_query                                | time_of_execution

2022.csv | select * from FLOWFILE where gradenm= '999'...  |  22-07-14 07:33:26

2022.csv | select * from FLOWFILE where gradenm<> '999'.. |  22-07-14 07:33:26 

 

I think that 'executequery.query.executiontime' attribute can deal with the time of execution part, but I don't know how to log the sqlquery and eventually save them into a table. A lot of awesome people gave me answers in previous posts but since I am a NB to Nifi I had to ask another question here. Thanks for the help in advance
