IDATAREADER INTERFACE ERROR NULL INDENTIFIER

Hi BIswajit_Das ,

Please try:
1. Make sure the data types of both the fields in a relationship are same.
2. Replace (null) values with 0 for decimal or whole number data types.

If you're still encountering issues after trying these steps, could you please provide more details about your scenario? Specifically:
What database or data source are you working with?
Can you share a snippet of the code where the error occurs, especially around the IDataReader usage?
What is the exact error message you're receiving?

Best Regards,

--> Is blank cells count as null values ?
