Hi,
I have fetched the AsyncApexJob from .Net.
In SOQL i got the "Bind variables only allowed in Apex code" Error.

My code is:

string res = "Failed";
            QueryResult query = null;
            string soql;
            soql = "SELECT Status,JobType,NumberOfErrors,CompletedDate FROM AsyncApexJob WHERE Status="+res+"";
            query = sfdcbind.query(soql);

Anyone help to solve this.
