SQL Bulk Copy failed

Hi @KEERTHANA JAYADEVAN ,

You are getting the error because the length of the data coming into destination column is bigger then the column size defined . I could suggest the following and you can read more here on the datatypes .

1. Define data type as varchar(a) , in the worst case scenario you can use varchar(max)
2. If you plan for use nvarchar . If you wish you can also use nvarchar(max) .

Best regards
Niko

*.csv/txt flat files always have host of problems where column delimiters, column separators, invisible characters like null terminators \0, special characters based on encoding, and line breaks are in the middle of the actual data. Or data elements are missing completely, i.e. column positions will vary.

The most reliable format for data feeds is XML enforced by an XSD. An XSD plays a role of a data contract between sender and receiver. It will guarantee proper data format/shape, data types, cardinality, encoding, and enforce data quality.

1. Double-check for any hidden characters or whitespace in your CSV file that might be causing the error.
2. Ensure that your CSV headers match the destination SQL table columns exactly.
3. Verify that the CSV file encoding matches what SQL Server expects (usually UTF-8 without BOM).
4. Use a staging table with all columns set to VARCHAR(MAX) to identify problematic rows.
