选择并连接所有表

Question

你好有人可以帮助我如何加入所有这些关于 serial_number 的表，我使用示例 "where name2="mynameis2";"我只能加入两个或 3 个表，但如果我 select 所有表我就做不到。

ERD 示例。

SQL 脚本：

     SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL,ALLOW_INVALID_DATES';

尝试

select * from table1 t1 
join table2 t2 on t1.idtable1 = t2.idtable1
join table4 t4 on t2.idtable2 = t4.idtable2
join table3 t3 on t4.idtable3 = t3.idtable3
join table5 t5 on t2.idtable2 = t5.idtable2
join table6 t6 on t2.idtable6 = t6.idtable6
join table7 t7 on t5.idtable7 = t7.idtable7
