Using MySQL Data Reader

Question

I\'m not familiar with using Data Reader, i need help with the following code, i want to retrieve a single data from the database.

MySqlDataAdapter data = ne         


        

Answer 1

reader["order_status"] returns object, since you told it is an already integer, you need to cast it to int first.

You need to use == operator as well since it is a equality operator. = operator is an assignment operator.

if ((int)reader["order_status"] == 0)

Or you can use GetInt32 method with it's zero-based column number. Let's say it's the first column that your query returns, you can use it like;

if(reader.GetInt32(0) == 0)

By the way, if you wanna get only single value, I strongly suspect you may wanna use ExecuteScalar method since it get's the first column of the first row. Then you can structure your query as SELECT order_status FROM ... etc..
