将JOIN的SQL查询转换为X 动态轴脚本

Question

我有一个不太简单的SQL查询，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')

我需要检索数据以更新

但是X 是错误的，没有成功。

希望对此获得专家建议，因为我是X scipting的新手

Answer 1

X 的旧版本不支持 Operator中的。使用 || 代替。
它以此处描述的限制形式支持，仅支持枚举。

您还需要声明您的缓冲区：

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));
}
