Question

我正在尝试从.csv文件中删除一些非常烦人的内联字符。我需要剥离！ CR LF，因为这些是我的导入。我有一个试图摆脱垃圾的过程，但它似乎没有工作。这是代码：

    CREATE TABLE #Cleanup
(
    SimpleData nvarchar(MAX)
)
BULK INSERT #Cleanup from '**********************\myimport.csv' 
SELECT * FROM #Cleanup

DECLARE @ReplVar nvarchar(MAX)
SET @ReplVar = CONCAT(char(33),char(10),char(13),char(32))
UPDATE #Cleanup SET SimpleData = replace([SimpleData], @ReplVar,'') from #Cleanup

SELECT * FROM #Cleanup

我的计划是如果愚蠢的换行符被删除，第二个选择不应该在那里。文字看起来像

js5t,1599,This is this and that is t!
hat,asdf,15426

该行应该读

js5t,1599,This is this and that is that,asdf,15426

看到我的困惑？删除连续字符！crlfsp 后，我将获取该临时表并将其输入到工作表中。

Answer 1

@seagulledge在对该问题的评论中说明CHAR(10)和CHAR(13)出了问题是正确的，或者至少是部分正确的。回车（CR）为CHAR(13)，换行（LF）为CHAR(10)。

但是，阻止此工作的主要因素不是这两个字符的顺序：新行是一个简单的事实 - 无论是\r\n还是{\n 1}} - 位于传入CSV文件中，因此BULK INSERT命令假定换行符分隔输入行（这对它有意义）。可以看到问题中的VARBINARY输出。有两行输出，都以0x开头。

此问题只能通过在调用BULK INSERT之前修复传入的CSV文件来解决。这样，将删除错误嵌入的换行符，以便每行作为单行导入临时表。
