mysql syntax to update record

What i开发者_开发问答s the mysql query syntax to update an existing record

Should be the same as other SQL syntax, no?

UPDATE TableName SET FieldName = Value WHERE Id = AnotherValue

And where does C# code come into this? Exactly how are you accessing the database?

It is all right here: http://dev.mysql.com/doc/refman/5.0/en/update.html.
Just wondering why you didn't google your question first.
