BCP在输出中添加空间

Question

此BCP声明在我的数据之间添加了一个空格。见图

这是DDL和示例数据 - 我需要更改哪些内容以便不添加空格？ （空栏）

Declare @TestMe Table
(
field1 varchar(20),
field2 varchar(20),
field3 varchar(20),
field4 varchar(20),
field5 varchar(20),
field6 varchar(20),
field7 varchar(20),
field8 varchar(20),
field9 varchar(20),
field10 varchar(20),
field11 varchar(20),
field12 varchar(20),
field13 varchar(20),
field14 varchar(20),
field15 varchar(20),
field16 varchar(20),
field17 varchar(20)
)

Insert Into @TestMe Values
('Blue', 'Red', NULL, NULL, NULL, NULL, 'Seven', 'Eight', NULL, NULL, Null, Null, 'Pink', 'Orange', 'NFL', 'Size', 'Last')

Declare @field1 varchar(20),@sql nvarchar(4000), @filename varchar(100)
Set @field1 = 'Blue'
Set @filename = 'C:\Test.csv'
Set @sql = 'bcp "SELECT ''one'',''two'',''three'',''four'',''five'',''six'',''seven'',''eight'',''nine'',''ten'',''eleven'',''twelve'',''thirteen'',''fourteen'',''fifteen'',''sixteen'',''seventeen'' UNION ALL SELECT CHAR(34)+CONVERT(varchar(10),[field1],101)+CHAR(34),CHAR(34)+CAST([field2] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field3] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field4] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field5] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field6] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field7] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field8] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field9] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field10] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field11] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field12] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field13] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field14] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field15] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([inventorycode] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field16] As VARCHAR(MAX))+CHAR(34) FROM [@TestMe] WHERE field1 = '''+@field1+'''" queryout "'
SET @sql = @sql + @filename + '" -c -t, -T -S '+@@SERVERNAME
exec master..xp_cmdshell @sql

Answer 1

脚本有2个问题。

首先，您不能将表变量与BCP一起使用。 BCP是连接到SQL Server的独立可执行文件，因此无法访问变量。使用BCP，您必须使用常规表或全局临时表。我已将脚本更改为使用全局临时表。

其次，在您的SQL查询中，您有[inventorycode]字段，该字段不在TestMe表中。我删除了它并添加了缺少的field17。

解决了这些问题后，我能够运行脚本生成没有间隙列的输出：

one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen,sixteen,seventeen
"Blue","Red",,,,,"Seven","Eight",,,,,"Pink","Orange","NFL","Size","Last"

使用以下代码。

create table ##TestMe
(
field1 varchar(20),
field2 varchar(20),
field3 varchar(20),
field4 varchar(20),
field5 varchar(20),
field6 varchar(20),
field7 varchar(20),
field8 varchar(20),
field9 varchar(20),
field10 varchar(20),
field11 varchar(20),
field12 varchar(20),
field13 varchar(20),
field14 varchar(20),
field15 varchar(20),
field16 varchar(20),
field17 varchar(20)
)

Insert Into ##TestMe Values
('Blue', 'Red', NULL, NULL, NULL, NULL, 'Seven', 'Eight', NULL, NULL, Null, Null, 'Pink', 'Orange', 'NFL', 'Size', 'Last')

Declare @field1 varchar(20),@sql nvarchar(4000), @filename varchar(100)
Set @field1 = 'Blue'
Set @filename = 'c\Test.csv'
Set @sql = 'bcp "SELECT ''one'',''two'',''three'',''four'',''five'',''six'',''seven'',''eight'',''nine'',''ten'',''eleven'',''twelve'',''thirteen'',''fourteen'',''fifteen'',''sixteen'',''seventeen'' UNION ALL SELECT CHAR(34)+CONVERT(varchar(10),[field1],101)+CHAR(34),CHAR(34)+CAST([field2] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field3] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field4] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field5] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field6] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field7] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field8] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field9] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field10] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field11] As VARCHAR(MAX))+CHAR(34),CHAR(34) + CAST([field12] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field13] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field14] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field15] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field16] As VARCHAR(MAX))+CHAR(34),CHAR(34)+CAST([field17] As VARCHAR(MAX))+CHAR(34) FROM ##TestMe WHERE field1 = '''+@field1+'''" queryout "'
SET @sql = @sql + @filename + '" -c -t, -T -S '+@@SERVERNAME
