好的..我已经放弃并回到我的老朋友 xpcmdshell。在整个响应及其代码中，xpcmdshell 将隐含下划线 (_)，因为我经常无法加载包含全名的页面。
首先，这只是我尝试过但不起作用的三件事（我不记得所有其他的）：
- 设置无计数
- 适用于没有临时表的任何 SP，但由于大多数 2500+- 我将研究如何使用它们，这是不可行的。
- 无操作
- 我创建了一个动态创建 No Op 的过程，但是在实现时我无法找到解决 SQL 陷入嵌套循环的方法。
- bcp 查询输出
因此，在多次抨击和谷歌搜索之后，我又回到了 xpcmdshell。下面的脚本（我将把它变成一个过程）接受一个 SP exec 语句和在其下运行它的数据库，将一个 xpcmdshell sqlquery 命令格式化为一个文件，执行该文件并将它的输出插入到一个临时表中，然后将这些结果的列标题提取到另一个临时表中。
