sql dependency Invalid object name '

Question

I am trying to use sql dependence, and I tried with making the connection with the squery, it is a very simple code:

public MyListener()
        {
            string query = "SELECT * FROM TransferToSIP WHERE hasBeenRead = false";
            SqlDependency.Start(getConnectionString(), query);
        }

That is the constructor. i call it like this:

new MyListener();

but I got this exception:

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll

Additional information: Invalid object name 'SELECT * FROM TransferToSIP WHERE hasBeenRead = false'.

There is no mistake at all in the database name or the field name.

what am i doing wrong please?

Answer 1

Try specifying a queue name instead of a query, or even without queue.

An example can be found on the reference page: https://msdn.microsoft.com/en-us/library/62xk7953%28v=vs.110%29.aspx

Answer 2

如果column（hasBeenRead）数据类型是位字符串，请尝试执行以下操作：查询=“ SELECT * FROM TransferToSIP WHERE hasBeenRead ='false'”;

Answer 3

"*" is not allowed. Try a selct statement with field names and maybe a dbowner
