Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Operand type clash: float is incompatible with time
You do have a type compatibility issue but it’s not due to a string, but rather a float trying to write to a Time column. I’m assuming your TiempoParo column is a Time datatype and you are trying to write a float value (0.03338…) to it.
Edit: Looks like you already figured this out based on your new topic. You really should keep these together so that people have context, and those trying to help you (like me) don’t spend time replying when you clearly already know the problem…
