php和mysql不写主键mysql可以自动生成主键;
想用pdo批量向mysql插入数据只能每条一个pdostarment->execute
看tp5.1的源码提供的方案是
INSERT INTO TT2 (name, name2, name3) SELECT :data__name_0,:data__name2_0, :data__name3_0 UNION ALL SELECT :data__name_1,:data__name2_1,:data__name3_1 UNION ALL SELECT :data__name_2,:data__name2_2,:data__name3_2
这样很可以一次查询
思考：
php连接oracle且在不使用触发器，预处理批量插入的解决方案
INSERT INTO TT2 (id, name, name2, name3) SELECT SEQ_TT2.nextval, A, B, C FROM (SELECT :data__name_0 A,:data__name2_0 B,:data__name3_0 C FROM DUAL UNION ALL SELECT :data__name_1,:data__name2_1,:data__name3_1 FROM DUAL UNION ALL SELECT :data__name_2,:data__name2_2,:data__name3_2 FROM DUAL)
然后给pdostarment传入占位符替换数组即可。避免了多次执行execute问题
