可能存在的问题：http://hi.baidu.com/ytjwt/item/22869f092b8146d872e6760a

我想把test中的数据导入到test1中，若a存在，则跟新b，c为test表中数据加上test1的数据
开始时候，这样写
insert into test1(a,b,c) select a , b , c from test ON DUPLICATE KEY UPDATE b=b+values(b),c=c+values(c);
就会出现ERROR 1052 (23000): Column 'b' in field list is ambiguous
这是因为在上面的sql中，MySQL不知道b到底是数据test 还是test1.所以就会出现上面错误。
后跟改为
insert into test1(a,b,c) select a , b , c from test ON DUPLICATE KEY UPDATE test1.b=test1.b+values(b),test1.c=test1.c+values(c);
就可以运行了
注意：values(b) 与values(c) 其实是代表multiple-row inserts的第二列跟第三列，跟表名没有关系，不能写成values(test.b)
mysql> insert into test1(a,b,c) select a , b , c from test ON DUPLICATE KEY UPDATE test1.b=test1.b+values(test.b),test1.c=test1.c+values(test.c);
ERROR 1054 (42S22): Unknown column 'test.b' in 'field list'
