When I ask you a great god, and gather data from each other in the interface to several contains the ID and the NAME of item 2, ID have corresponding NAME in the corresponding dictionary, for example:
in a dictionary10 corresponding ID NAME for China, but the actual interface fetching data has caught ID "10" constraint checking, check the ID "10", the data really satisfy the conditions is found in the dictionary, the NAME catch obtain content for "American" constraint checking "American" also exists in the dictionary, but the actual values in two corresponding,

Everyone a great god is there any way can under construction in the table can use any way to avoid while two values can take to can not match, but two, thanks!
