SQL Server 2008:PIVOT抛出错误'varchar值的转换'xxx'溢出了一个int列.

Question

在使用PIVOTUDF将CSV字段转换为表格后,我正在使用SQL Server 2008 功能.

为了显示此错误,我正在取消将CROSS APPLYCSV字段添加到UDF的第一步,以获取我在下面的代码示例中手动创建的表.

CREATE TABLE #TCMDRES (
    SYS_NR BIGINT,
    DAT_TE VARCHAR(150),
    ID CHAR(1)
)

-- ,,,,,,WIN ASDF v2,20100406.BAK,32515325772,32514331136,
-- After being separated and put into columns 1-11...
INSERT INTO #TCMDRES
VALUES(1,'','X'),(2,'','X'),(3,'','X'),(4,'','X'),(5,'','X'),(6,'','X'),(7,'WIN ASDF v2','X'),
(8,'20100406.BAK','X'),(9,'32515325772','X'),(10,'32514331136','X'),(11,'','X')

SELECT *
FROM #TCMDRES

-- This errors out with:
-- Msg 248, Level 16, State 1, Line 16
-- The conversion of the nvarchar value '32514331136' overflowed an int column.
SELECT ID, [8] AS FIL_NA, [10] AS FIL_SZ_NR
FROM
    (
    SELECT DAT_TE, SYS_NR, ID
    FROM #TCMDRES a 
    ) a
PIVOT (MAX(DAT_TE) FOR SYS_NR IN ([8],[10])) AS pvt
WHERE [10] <> 0

DELETE FROM #TCMDRES

-- Try again but drop the last two digits from column 10...
INSERT INTO #TCMDRES
VALUES(1,'','X'),(2,'','X'),(3,'','X'),(4,'','X'),(5,'','X'),(6,'','X'),(7,'WIN ASDF v2','X'),
(8,'20100406.BAK','X'),(9,'32515325772','X'),(10,'325143311','X'),(11,'','X')

SELECT ID, [8] AS FIL_NA, [10] AS FIL_SZ_NR
FROM
    (
    SELECT DAT_TE, SYS_NR, ID
    FROM #TCMDRES a 
    ) a
PIVOT (MAX(DAT_TE) FOR SYS_NR IN ([8],[10])) AS pvt
WHERE [10] <> 0

DROP TABLE #TCMDRES

总而言之,如果你尝试PIVOT使用大值,即使它被存储为a VARCHAR,它也无法尝试将其转换为INT.

有没有人有任何关于如何解决这个问题的想法,或者它是否可以修复？似乎是PIVOT功能的限制......

Answer 1

这是你的WHERE条款. 0是一个INT.试试这个(为我测试):

WHERE [10] <> CAST(0 as bigint)

或者,每个Lamak:

另一种方式 WHERE [10] <> '0'
