Hi Experts,

String concatenation and Stringbuider which one is the faster.
what is the better appraoch to use while framing queries.

String concatenation will create one object or multiple?(I guess it will create one object).


String concatenation:
String query = select * from testsample where testsample_id='"+id+"'
                          +" and name='"+name+"'
                          +" and deleteflag ='"+N+"'

StringBuilder :
StringBuilder sb = new StringBuilder();
sb.append("select * from testsample where testsample_id='"+id+"'");
   .append("and name='"+name+'"");
   .append("and deleteflag ='"+N+'"");
