假设我正在 SQL 服务器管理工​​作室中执行 sql 文件.

Let's say I am executing the sql file inside the SQL server management studio.

推荐答案

服务器正在执行 t-sql.它不知道客户端从哪里加载文件.您必须在脚本中嵌入路径.

The server is executing the t-sql. It doesn't know where the client loaded the file from. You'll have to have the path embedded within the script.

DECLARE @RelDir varchar(1000)
SET @RelDir = 'D:\temp\'
...

也许您可以以编程方式将路径放入 .sql 脚本文件中的 SET 命令中，或者您可以使用 sqlcmd 并将相关目录作为变量传入.

Perhaps you can programmatically place the path into the SET command within the .sql script file, or perhaps you can use sqlcmd and pass the relative directory in as a variable.
