NIFI - SQL Server Lookup

budati — Tue, 17 Sep 2019 22:39:33 GMT

Hi,

I am in need of SQL Server lookup, found this library https://github.com/mrcsparker/nifi-sqllookup-services-bundle but there are no good examples especially when dealing with incoming CSV text file. Appreciate if anybody can point me to an article or sample workflow that does something similar.

Thanks in advance

Did you tried using NiFi DBCPConnectionLookup service and we can make Dynamic lookup from RDBMS.

Please refer to this link for more details regards to LookupService.

@Shu_ashu : Thank you so much for the link, it covers part of my need.

The other thing is to assign the lookup value to attribute so I think the solution is

ExecuteSQL -> ConvertAvroToJson -> EvaluateJsonPath

can we do it in one step instead of 3 like above? All I am pulling is one field from the database table.

Query: select id from table A

@budati

i don't think there is a way to combine all 3 processors into one.

We still need to use ExecuteSQL -> ConvertAvroToJson -> EvaluateJsonPath to extract the values from the flowfile.
