Question

我有问题。我使用这段代码：

 Report report = new Report();
 report.Load("sample.fpx");

 report.Print();`

我看到打印对话框，单击＆＃34;打印＆＃34;，但是不会打印文档？问题是什么？

Answer 1

您应该在打印前准备报告

Answer 2

使用

WITH CTE AS(
    SELECT *,
        Rn = ROW_NUMBER() OVER(PARTITION BY step ORDER BY id)
    FROM TestTable
)
SELECT
    c.id, 
    c.step, 
    valA = ISNULL(c.valA, x.valA), 
    valB = ISNULL(c.valB, x.valB),
    c.valC
FROM CTE c
OUTER APPLY(
    SELECT TOP(1) *
    FROM TestTable t
    WHERE
        t.id > c.id
        AND t.step = c.step
    ORDER BY t.id
) x
WHERE
    Rn = 1
    OR (c.valA IS NULL OR c.valB IS NULL)

UNION ALL

SELECT
    id, step, valA, valB, valC
FROM CTE
WHERE
    Rn = 2
    AND valA IS NOT NULL
    AND valB IS NOT NULL
ORDER BY Id;

加载方法适用于模板。

快速报告无法打印
