@rafy    You shouldn't need to extract the content as an attribute. Instead, use ReplaceText to replace the contents of the flowfile with the SQL template, like this: INSERT INTO my_table (xml_col) VALUES ('$1')   Where $1 is a reference to the default regex capture group that captures the entire content. In reality, it requires a bit more labour, since you have to escape the single quotes in the XML first.   Cheers, André   ... View more

Hi, @code ,   I don't think this is actually possible. Even if there was a way to enter a literal value of NULL for the lookup value, the controller service is probably comparing the lookup value with an "equals" operation (e.g. mytable.mykey = lookup_value) and in relational databases the comparison NULL = NULL is always evaluated to FALSE. (the only way to compare values with a NULL is to use the operator IS).   What you can try to do is to create a view on top of that table that converts NULLs to some string that you can use to compare to lookup values in NiFi. Then you can use the view name in the controller service configuration instead of the table name.   For example:     CREATE VIEW v_mytable AS SELECT NVL(mykey, '<NULL>') as key_without_nulls, * FROM mytable     Be aware of potential performance implications of this, since this could prevent existing table indexes from being used for lookups.   Cheers, André     ...

@Markyd ,   Functions used in Hive queries are usually passed to the Hive service as is. I don't think the ODBC driver does any particular processing or validation of those functions. At the end of the day it's a matter of whether the Hive version you're using supports that function or not, and this depends on the Hive version being used, not the driver version.   Here you can see a comprehensive list of Hive functions and the associated Hive version where they were introduced: https://cwiki.apache.org/confluence/display/hive/languagemanual+udf   Which version of Hive are you using? Are you using the Cloudera ODBC Drivers for Hive? Which version?   Cheers, André   ... View more
