One, you should not be using string concatenation with unvalidated user input. EVER!! Use a parameterized query at the very least.

Perhaps I misunderstood the question, but, if you are assuming that given a filename SQL Server will automatically insert the contents of the file to the database then you are mistaken.

See here[^] for how to add files to SQL Server

Solution 2

Dear Member,

The problem is with your file[0]'s value. Check for verbatim. File Path should be like "C:\...", but in program it gets values like "C:\\...". So, check that first.

Worried !!!! How to do so? Go for Tracing with F11. Hope this will resolve your issue.

If the solution does not work, please comment on this solution.
