Class LoadingError

java.lang.Object

net.snowflake.client.api.loader.LoadingError

public class LoadingError
extends Object

Wrapper for data format errors returned by the COPY/validate command.

This class encapsulates error information from failed data loading operations. It provides details about what went wrong, where in the file the error occurred, and the rejected record data.

Usage Example

 LoadResultListener listener = new LoadResultListener() {
   public void addError(LoadingError error) {
     System.err.println("Error in file: " + error.getFile());
     System.err.println("Line: " + error.getProperty(ErrorProperty.LINE));
     System.err.println("Error: " + error.getProperty(ErrorProperty.ERROR));
   }
   // ... implement other methods
 };
