MSSQL Node Transfer Failure

Hello i have a big problem.
I receive data from a MQTT Broker via HTTP - Request, that works.
I split the Data into Key:Value, that works too.
now i want to become some Data to my MSSQL Server with the node MSSQL PLUS.
I get the Data into my MSSQL Server in the right Table, but it send some entries very often and thats not what it should do. Anyway i get some Failure Validation failed for parameter 'deltaV'. Invalid number for example or Unable to evaluate value for parameter at index [6] named 'deltaV'.
i get around 200 objects from MQTT Broker and want to get the Data in splitted into my columbs, but finally i get like 15.000 entries in my Server instead of 200.

Put a debug node before the MSSQL node - what is inside msg.payload.js.state.deltaV?

Cant answer that if you dont share your flow. However, I can pretty much gurantee, if you have 15000 entries, it is because MSSQL node was called 15000 times (i.e. you have a fault with your flow.)

To prove this, attach a counter before the MSSQL node.

counter flow...
