Session["PersonID"] is empty

Empty string is OK. Null would give the SQL error OP has but then calling .ToString() would have given an object reference error first.

If you look closely, OP clears parameters after filling them all in and before calling ExecuteNonQuery. :)

Also, since the Person_ID parameter is defined as an int, you have to provide it an int, not a string value.

Use particular columns in the insert statement to which you are inserting the values.


Insert into Education_Degree_TB (field1, field2,...,field7) values(@Person_ID,@Field_ID,@SubField_ID,@Degree_Education,@University_Name,

Right after you add all the parameters you then clear them out.

Remove this line:

I remove this Line cmd2.Parameters.Clear();
but now I face to below error
Additional information: Error converting data type nvarchar to date.

Do you understand what the error means? It says that you are passing a string into a date parameter that is not an actual date.

Actually I did not understand what the error means. When I insert the data, I receive the input from session also the Data Type of my Parameter is int
