必须在 SQL 服务器中使用 BCP 声明标量变量
Must declare scalar variable with BCP in SQL Server
我的存储过程代码有以下部分，但出于某种原因，我不断收到错误消息：
- 必须声明标量变量“@query”
- 无法准备语句
我也在尝试使用 BCP 导出到文件，@query 字符串是一个复杂的字符串。这是代码：
@market varchar(20) = null,
@date datetime = null
AS
BEGIN
SET NOCOUNT ON;
set @date =
CASE datepart(dw,getdate())
WHEN 1 THEN dateadd(day, -1, convert(varchar, getdate(), 101))
WHEN 2 THEN dateadd(day, -2, convert(varchar, getdate(), 101))
WHEN 3 THEN dateadd(day, -3, convert(varchar, getdate(), 101))
WHEN 4 THEN dateadd(day, -4, convert(varchar, getdate(), 101))
WHEN 5 THEN dateadd(day, -5, convert(varchar, getdate(), 101))

@DBNull 是正确的。
您需要将 bcp 命令的实际执行更改为类似这样的内容....
SET @query = 'bcp "' + @query + '" queryout "C:\bcptest.txt" -T -c -t,';
EXEC xp_cmdshell @query;
您需要将查询用引号引起来，并且您可以使用 xp_cmdshell 执行的实际命令有 varchar(8000) 或 nvarchar(4000) 的限制。我建议您考虑将查询包装在视图或存储过程中。这不仅会大大增强代码的可维护性，而且您无需担心大小限制，更不用说您现在必须做的所有单引号转义了。
希望对您有所帮助。
