how to use procedure call in Apache Nifi ExecuteSQL processor (with both in and out parameter)

Question

如何在Apache Nifi ExecuteSQL处理器（同时带有in和out参数）中使用过程调用专门用于说出参数。

Answer 1

Not with ExecuteSQL, but with ExecuteProcess you could run a command-line utility like sqlplus, here's an example of someone who got that working:

Also the post hints at possibly using ExecuteScript to achieve this, I have a blog post that shows the basic setup, although you'd be looking to use a CallableStatement at that point: http://funnifi.blogspot.com/2016/04/sql-in-nifi-with-executescript.html
