Question

I am having a problem with inserting new data into MS Access 2007 file. It say I am having an incorrect SQL statement.

What is the problem here? I am not good at SQL. Please point out my error.

            try
            {
                // Open database connection.
                objOleDbConnection.Open();
                objOleDbCommand.CommandText = 
                    "INSERT INTO PersonalData (Type, UserName, Password) VALUES ('" + cmbType.Text + "','" + txtUserName.Text + "','" + txtPassword.Text + "')";
                // Execute creating table command.
                objOleDbCommand.ExecuteNonQuery();
            }

Answer 1

Both Type and Password are reserved words. See Problem names and reserved words in Access.

If you must keep those as the field names, surround them with square brackets in your INSERT statement so the database engine will know to interpret them as fields:

"INSERT INTO PersonalData ([Type], UserName, [Password]) VALUES ...

On that same web page, follow the link for Database Issue Checker Utility. That utility can warn you about problems with reserved words in your application, and other potential troublesome issues.

Edit: If PersonalData includes additional fields which are required and do not have default values assigned, you must include those fields with values in your INSERT statement, or it will definitely fail.
