Question

我已经看到其他文章谈论使用OPENQUERY调用远程服务器上的函数，但是我无法使它在下面的简单函数中起作用，该函数返回一个数值。（我无法更改此函数，所以我被其参数和返回值所困扰）：

DECLARE @ProjectDepartment NUMERIC(12,0);
DECLARE @Department NUMERIC(12,0);

SET @Department = 104;

SET @ProjectDepartment = db.schema.GetSharing(@Department, 'DeliveryPlace');

我尝试过：

SELECT
  @ProjectDepartment = @ProjectDepartment
FROM
  OPENQUERY(server,
  'SELECT @ProjectDepartment
    FROM db.schema.GetSharing(@Department, "DeliveryPlace")');

和

EXECUTE @ProjectDepartment = server.db.schema.sp_executesql
  N'SELECT db.schema.GetSharing(@Department, "DeliveryPlace")',
  N'@Department NUMERIC(12,0)',
  @Department = 104;

和

DECLARE @sql NVARCHAR(4000);

SET @sql = 'SELECT' +
CAST(@ProjectDepartment AS NVARCHAR(12)) +
'FROM OPENQUERY(server,
''SELECT ' + CAST(@ProjectDepartment AS NVARCHAR(12)) +
' = db.schema.GetSharing(' + CAST(@Department AS NVARCHAR(12)) + ', "DeliveryPlace")'')';

EXEC(@sql);

我正在使用SQL Server Management Studio 17.9.1。

已添加：

我将其添加到测试例程中：

Use db
GO

DECLARE @ProjectDepartment  NUMERIC(12,0);
DECLARE @Department         NUMERIC(12,0);

SET @Department = 104;

EXEC @ProjectDepartment = server.db.schema.sp_executesql
N'SELECT GetSharing(@Department, "DeliveryPlace")',
N'@Department NUMERIC(12,0)',
@Department=@Department;

我收到此错误：

Could not find stored procedure 'db.schema.sp_executesql'.

当我在实际函数中使用此代码时，仍然出现此错误：

Remote function calls are not allowed within a function.

如何将该本地函数调用转换为远程函数调用？
