How to cast SOQL result as a string

I am attempting to pull the state__c value from the site__c object where the site__c.id matches the selected value from a selectList.  I have tried 2 different ways and am unable to avoid errors. 

 

-----------------

Attempt #1

    public String siteState
    {
        get {return [SELECT state__c FROM site__c WHERE id = :site LIMIT 1]; }
        set;
    }

 

The error I receive is:

Error: Compile Error: Return value must be of type: String at line 17 column 14

-----------------

Attempt #2

    public String siteState
    {
        get
        {
            String tmpState = [SELECT state__c FROM site__c WHERE id = :site LIMIT 1];
            return tmpState;
        }
        set;
    }

 

The error I receive is:

Error: Compile Error: Illegal assignment from LIST:SOBJECT:Site__c to String at line 19 column 13

-----------------

 

Any help is greatly appreciated.

Remember that your SOQL is returning an object, in your case a site__c object.

 

what you need to do is get just the field member you are interested in, assuming it is already the correct data type for your need.

 

 

Attempt #1

    public String siteState
    {
        get {return [SELECT state__c FROM site__c WHERE id = :site LIMIT 1].state__c; }
        set;
    }
 
or
 
 
   public String siteState
    {
        get
        {
            String tmpState = [SELECT state__c FROM site__c WHERE id = :site LIMIT 1].state__c;
            return tmpState;
        }
        set;
    }

Thank you very much.  Needless to say, I'm a force.com newbie and am still struggling through some of the basics.  I really appreciate your help.  Your response makes perfect sense.

Can someone tell me how to test this in unit testing.It solved my problem but created another!
I keep getting an error message 'System.QueryException: List has no rows for assignment to SObject' and I'm not sure how to tackle this problem.
 
Thanks
