Question

我必须将1450列excel文件中的数据插入到SQL表中。如果我有表格部分，我认为唯一可能的方式，例如500个列表中的3个。我的问题是，工作表上的一些单元格包含5-10个字符，有些单元格最多可包含100个字符。我创建了一个包含500列的表，列是VARCHAR（MAX）。如果我使用以下插入语句，我不会收到任何错误消息：

INSERT INTO [table] ([column1], [column2]) 
VALUES 
(
CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)),
CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)) + CAST(REPLICATE('A', 5000) AS VARCHAR(MAX)),
)

这一行共有120.000个字符。我运行它时没有收到任何错误消息，它将数据插入表中，我也可以读取它，一切正常。

但是，如果我尝试运行以下查询，则收到错误消息：

Cannot create a row of size 13071 which is greater than the allowable maximum row size of 8060.

查询：

第二个查询包含500 * 50（总计25.000）＆＃39; A＆＃39;字符，这比120.000字符要少得多，但我得到了上面写的溢出错误。

请帮助我们，我不知道，出了什么问题......如何插入我需要的所有内容而不会出错？我尝试了在这个主题上可以在互联网上找到的所有内容，但没有任何帮助，TEXT类型不起作用，REBUILD表也没有任何效果等等......

varchar（max）是LOB数据，如果它适合行，它就存储在行中，否则它会在行中放入一个24字节的指向LOB根结构的指针，该结构包含指向LOB页面的指针。因此，在500 LOB页面的情况下，将有500个指针x 24个字节= 12000个字节+ 2个字节用于行偏移数组：2 x 500 = 1000，我们有13000个字节;可能我不记得其他什么除了这些13000字节之外，还应该存储开销，但无论如何你都无法将它们放入1页。如果你只放了2列，那行只会存储2 x 24 + 2 x 2字节的数据，只有2个指针，所以完全没有问题。最终数据（120.000个字符不是存储在行中，而是存储在形成LOB树的LOB页面块中

将8K +数据插入表有时可以工作，有时不工作
