2 个列表之间的 SQL 字符串检查

Question

我想遍历每个购物篮 SKU 的每一行，并根据订单 SKU 进行检查。新列将计算每行中有多少个匹配项。这可能吗？

我尝试过的任何事情都没有运气。

Answer 1

我按照 SQL count the number of comma-separated string match in another string 中的示例进行操作，并将其应用到您的示例中。

CREATE TABLE Example 
(
    Basketld    INT,
    OrderNo VARCHAR(512),
    BasketSKUs  VARCHAR(512),
    OrderSKUs   VARCHAR(512)
);

INSERT INTO Example (Basketld, OrderNo, BasketSKUs, OrderSKUs) VALUES
    (20009610, 'MFTJZ3', '064008, 064011, 064057, 064074, 064075, 064092, 064093, 064094, 064095, 06...', '226374, 410990, 561242, 569197, 630684, 670071, 685224, 685225, 685226, 706226, 706227, 706228, 706229, 706230, 706231, 706232'),
    (20011137, 'MFTJZ3', '856354, 857133, 857134, 857135, 857511, 857512, 857513, 857530, 857646, 85...', '226374, 410990, 561242, 569197, 630684, 670071, 685224, 685225, 685226, 706226, 706227, 706228, 706229, 706230, 706231, 706232'),
    (20011138, 'MFTJZ3', '055522, 055523, 055524, 055525, 089893, 112935, 119355, 634691, 634692, 65...', '226374, 410990, 561242, 569197, 630684, 670071, 685224, 685225, 685226, 706226, 706227, 706228, 706229, 706230, 706231, 706232');

SELECT * FROM Example

;with Baskets as
(
  select Basketld,OrderNo, Value = trim(b.value)
  from Example a
  cross apply string_split(a.BasketSKUs, ',') b
), Orders as
(
  select Basketld,OrderNo, Value = trim(b.value)
  from Example a
  cross apply string_split(a.OrderSKUs, ',') b
)
select
    b.Basketld,
    ItemCount = count(1),
    MatchCount = count(o.value)
from Baskets b
left outer join Orders o
    on b.Basketld = o.Basketld
        and b.Value = o.Value
group by b.Basketld
