It solved my problem: Thanks For your help.............Mylife

string qr = 'select id, CaseNumber from '+match+' where id='+BrowserURLId; list<sObject> result =Database.query(qr); Same Error: I unexpected token: '500900000070l'

I passed record id through variable BrowserURLId. In this scenario BrowserURLId dynamically passed record id value is 500900000070l0d.

Dear Prady, As per my understand “500900000070l” is not a variable; that is record id number (BrowserURLId=500900000070l0d).

Dear techtrekker, Thanks for your replay, I tried your solution. But still I am getting the same problem. I am showing controller code and snap shot of my issue. public string BrowserURL = System.URL.getSalesforceBaseUrl().toExternalForm(); public string getgraburl() { return BrowserURL; } can you please suggest me how can i achieve this problem. thanks mylife....
