String Binary data will be truncated error when using a Summary table.

Increase the column length: If the longer data is valid and needs to be stored, the best solution is to modify the table schema to increase the column size (e.g., ALTER TABLE Example ALTER COLUMN Name VARCHAR(50)).

Truncate the data before insertion: If you cannot alter the table schema and it is acceptable to lose the excess data, you can programmatically truncate the string values to fit the column size using functions like LEFT() or similar string manipulation functions in your application code or SQL query.

Implement error handling: In your application code, add checks to verify data lengths before attempting the database operation, and handle cases where data might be too long to prevent the operation from failing entirely.
