Hello, My dataflow is as follow: My purpose is to create a table from a csv file and then put the data in this table. Everything is working good but I need to check if the table is created before storing the csv file. So I used the Execute SQL to run this query: select count(table_name) from information_schema.tables where table_name='warranty' But it returns only the number of rows and not the flowfile. My test is if number of row is one so I execute the rest. So I need to use dataflow which can check if the table is well created and execute the other processors if not it stop every thing. Can you help me plz I know that i can find another way but don't find ideas. Thank you for your help. ... View more
