Hi, If you really want use the ConvertJsonToSQL processor, you need to have a field in your json object with the SQL inner query. You can also use the EvaluateJSonPath -> replaceText -> putSQL flow to achieve that. ... View more

With the UpdateAttribute, you can add your own property. (With the '+' button in the 'Properties' tab) Add a property with the name : Sis_Grp.Dom and the value : ${ZComponent:substringAfter('"'):substringBefore('"')} (the argument for the substringBefore is double quote between simple quotes.) and a second with the name : Name and the value : ${ZComponent:substringAfter('Name="'):substringBefore('"')} You can find all the Nifi Expression language here ...

Hi, Did you schedule your GetHTTP processor ? By default, it continually runs. So your data are continually fetched. You have to configure this property in the "Scheduling" tab. An easy way, in test : keep the "Timer driven" strategy and set the Run Schedule with a big interval. So you can start your flow and stop it before the second execution. ... View more

1 - ExecuteSQL -> 2 - ConvertAvroToJSON -> 3 - splitJSon -> 4 - EvaluateJsonPath -> 5 - UpdateAttribute -> 6 ExecuteSQL -> 7 - replaceText -> 8- putSQL. 1 - 2 - 3 : query your table and split by row. You will have one flowfile by row. Use $ for the JsonPathExpression in the split processor. 4 - Retrieve the query_id and the query_execute in two attributes of each flowfile (values of your properties are $.query_id and $.query_execute) 5 - Create a new attribute query_startTime with the value ${now():format('HH:mm:ss') 6 - Execute the query ${query_execute} 7 - Write your insert query : INSERT INTO queryExecutionInfo VALUES (${query_id}, ${query_startTime},{${now():format('HH:mm:ss')); 8 - Execute your insert I think this flow works, maybe someone will have something efficient. ...

Hi A common flow to modify your data is : ConvertAvroToJson -> splitJson -> EvaluateJsonPath -> UpdateAttribute So you will have one flowfile by row and with the EvaluateJsonPath you convert your fields as attributes of this flowfile. After that you can use UpdateAttribute to modify an attribute or add new one. You can use Nifi Expression Language. ... View more

Hi, I think you can do that with the QueryRecord processor. Add a new property, whatever the name and the content may be something like "select Subject, count(Name) as nb from flowfile group by Subject". Set correctly the schemas for the reader and the writer and you will find the result of the query as a new relationship of your processor. (A new relationship with the name of your property will appear) ... View more
