Unhandled exception. System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '3'. Incorrect syntax near '3'

This error occurs when there is a syntax error in a SQL query. In this case, the error message suggests that there is an issue with the number 3 in the query.

To resolve this issue, check the SQL query for any syntax errors, such as missing or extra quotation marks, parentheses, or commas. It's also possible that the query is missing a keyword or has an incorrect keyword.

If you are still unable to resolve the issue, try breaking down the query into smaller parts and testing each part individually to identify the problematic section. You may also want to consult with a database administrator or developer for assistance.
