C＃到SQLite电子邮件字符串

Question

Trying to store an email address from a .NET application into a SQLite database. The DB is pre-built within the SQLite studio and I have already connected my project to it.

Problem is, when I attempt to pass an email address (String), into the DB with the following:

Account.Email = test@test.com
string SQLText = "INSERT " + "INTO Account (Email) " + "VALUES (" + Account.Email + ")"
SqliteCommand Command = new SQLiteCommand (SQLText, Base);
Command.ExecuteNonQuery ();

Account being a class that holds the email string and Base being a reference to the DB with C#.

I get

SQLiteSyntaxException: near "@Test": syntax error

What should I do to the string in order for it to ignore the @ as a parameter declaration in sql?

Any advice?

Answer 1

I don't know about sqlite specifically, but with my knowledge of SQL syntax in general, the resulting statement should look like (assuming the email address is email@test.com ):

INSERT INTO Account(Email) Values ('email@test.com')

But your code produces the following statement:

INSERT INTO Account(Email) Values (email@test.com)

You'll notice the single quotes are missing from the second line.

Also, you might want to look into what a SQL injection attack is. Building your queries by concatenating strings with user input opens you up to this type of attack.
