2)Create New  External Content Type in SPD with SQL connection  with User's Identity as Authentication mode.
3)Create required operation like read, write for Table Created in SQL
4)In CA,In Secure Store Service , Create Target application which maps the Credentials for External Content Type (If necessary)
