php处理ORACLE自增主键问题

Posted 2020-10-26 八千岁将军

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
