将 SQL 查询与连接转换为 X++ Dynamics AX 脚本

Question

我有一个 SQL 查询并不那么简单，因为它包含 Join

SELECT *
 FROM table1 a inner join table2 b on a.field1 = b.field1
 inner join table3 c on a.field2 = c.field2 
 inner join table4 d on c.field3 = d.field3
  inner join table5 e on c.field4 = e.field4
 WHERE a.location = 'asia' AND  b.modType = 1
 and c.discount = 'sample'
 and d.name =  'hello' 
and e.name in ('one', 'two', 'three')

我喜欢将其转换为 X++ 脚本，这就是我所做的

  while select forUpdate 
        table1  join table2 where table1.field1 == table2.field1 
        join table3 where table1.field2 == table3.field2
        join table4 where table3.field3 == table4.field3
        join table5 where table3.category == table5.recid

        && table1.location  == 'asia' && table2.modtye == 2
        && table3.discount == 'sample' 
        && table4.name ==  'hello' 
       && table5.name in  ('one', 'two', 'three')

我需要检索数据进行更新

但是x++错误，不成功

希望得到专家的建议，因为我是 X++ scipting 的新手

旧版本的 X++ 不支持 in 运算符。请改用 ||。
它以 here 描述的受限形式受支持，仅支持枚举。

您还需要声明缓冲区：

Table1 table1;
Table2 table2;
Table3 table3;
Table4 table4;
Table5 table5;
while select forUpdate table1  
    join table2 where table1.field1 == table2.field1 
    join table3 where table1.field2 == table3.field2
    join table4 where table3.field3 == table4.field3
    join table5 where table3.category == table5.recid
      && table1.location  == 'asia' && table2.modtye == 2
      && table3.discount == 'sample' 
      && table4.name ==  'hello' 
      &&(table5.name == 'one' || table5.name == 'two' || table5.name == 'three')
{
    info(strFmt('%1 %2 %3', table5.name, table4.name, table3.discount));
}
