code of service:

[basichttpbindingservicemetadataexchangeendpoint]     [aspnetcompatibilityrequirements(requirementsmode = aspnetcompatibilityrequirementsmode.required)]     [servicecontract]     public class wcfservice      {         // test service, use visual studio wcf test client         // set endpoint http://<your server name>/_vti_bin/webservices/wcfservice.svc/mex         [operationcontract]         //[webget(uritemplate = "helloworld", responseformat = webmessageformat.json, bodystyle = webmessagebodystyle.bare)]         [webinvoke(requestformat = webmessageformat.json, uritemplate="/helloworldm", bodystyle = webmessagebodystyle.wrapped)]         public string helloworld()         {             return "hello world wcf , sharepoint 2010";         }     }

try use multiplebaseaddresswebservicehostfactory instead of multiplebaseaddressbasichttpbindin­gservicehostfactory in svc files.

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
