Invalid object name '@database.dbo.sometable'

Answer 1

You cannot directly parameterized the tableName. The only way you can do that is to make a dynamic SQL Statement.

eg,

CREATE PROCEDURE proce @database VARCHAR(50)
AS
BEGIN
    DECLARE @SQLQuery AS NVARCHAR(500)
    SET @SQLQuery = 'SELECT * FROM [' + @database + '].[dbo].[sometable]'
    EXECUTE(@SQLQuery)
END
GO
