Có ai đã viết hoặc biết truy vấn, sẽ tìm và thả tất cả các thuộc tính mở rộng (Cơ sở dữ liệu, bảng và cấp cột) có tên đã cho không? Tôi biết tôi có thể thả một thuộc tính mở rộng qua proc được lưu trữ sp_dropextendedproperty.Truy vấn để thả tất cả các thuộc tính mở rộng có chứa một tên nhất định
Liên kết đến nội dung nào đó có thể hữu ích cho bạn. http://social.msdn.microsoft.com/Forums/en/transactsql/thread/747cb7c2-b176-4f75-9d92-c5a9360b4ed3
Tạo báo cáo sp_dropextendedproperty exec động cho mỗi thuộc tính được tìm thấy.
Đối với tôi, tập lệnh trong liên kết của Mikael không tạo ra các giọt cho tất cả các thuộc tính mở rộng, ví dụ: cho các lượt xem. Những gì đã làm việc là một kịch bản mà Jamie Thomson đã tạo ra, mà bạn có thể tải về từ article này.
Tôi đã dán kịch bản của mình ở đây (đầy đủ với sự thừa nhận, trong trường hợp bài viết được lấy ra):
/*
This script will generate calls to sp_dropextendedproperty for every
extended property that exists in your database.
Actually, a caveat: I don't promise that it will catch each and every
extended property that exists, but I'm confident it will catch most of them!
It is based on this:

Adam actually provides a script at that link to do something very similar
but when I ran it I got an error:
Msg 468, Level 16, State 9, Line 78
Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation.
So I put together this version instead.
Use at your own risk.

sys.functions không tồn tại. Bạn đang chạy phiên bản SQLServer nào? – TheLegendaryCopyCoder
Câu trả lời trước không hoạt động chính xác cho tôi - chúng không xóa thuộc tính mở rộng cho trình kích hoạt cơ sở dữ liệu, bộ sưu tập hoặc chỉ mục lược đồ xml. Tôi tìm thấy điều này script to delete extended properties (nhận xét được dịch từ tiếng Nhật bằng Google dịch), đã hoạt động hoàn hảo cho tôi.
Cảnh báo: này thực loại bỏ tất cả các thuộc tính mở rộng, chứ không phải xuất ra một truy vấn để làm như vậy, như câu trả lời trước làm. Thay vào đó, thay đổi hành vi để xuất truy vấn, hãy thay đổi từng số EXEC (@sql) thành PRINT (@sql).
