问题
I have a SQL query that is not that simple as it contains 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')
I like to convert it to X++ scripting, here's what I did
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')
I need to retrieve the data to update
But the x++ is wrong and unsuccessful.
Hope to get expert advice on this as I am new to X++ scipting
回答1:
Older versions of X++ do not support the in operator. Use || instead.
It is supported in a restricted form described here, only supported for enums.
Also you will need to declare your buffers:
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));
}
