在mysql中,可以利用“SELECT”语句和“INNER JOIN”关键字来查询交集,求交集数据,语法“SELECT 字段名 FROM 数据表1 INNER JOIN 数据表2 USING(字段名);”。
droptablet1;
droptablet2;
createtablet1(id intprimarykey,nicknamevarchar(20),playNumvarchar(20));
createtablet2(id intprimarykey,nicknamevarchar(20),playNumvarchar(20));
insertintot1values(1,1,10);
insertintot1values(2,2,20);
insertintot1values(3,3,30);
insertintot2values(1,1,10);
insertintot2values(2,2,200);
insertintot2values(3,33,300);
commit;
