Trong bài viết này Kỹ thuật sẽ hướng dẫn các bạn xử lý trường hợp xảy ra trên hosting khi import database xuất hiện thông báo lỗi: `

1273 - Unknown collation: 'utf8mb4_unicode_520_ci'`

Lỗi như trên là vì phiên bản MySQL hiện tại mà hosting đang chạy không hỗ trợ cho bảng mã utf8mb4_unicode_520_ci.

Cũng có lúc bạn sẽ gặp lỗi: `

1273 - Unknown collation: 'utf8mb4_unicode_ci' `với lý do tương tự.

Bạn có thể tạo một file info.php để kiểm tra phiên bản MySQL đang chạy trên hosting của mình là gì để biết phiên bản đó có hỗ trợ bảng mã đó hay không.

<?php phpinfo();?>

Theo như hình phiên bản MySQL mà hosting của Kỹ thuật đang dùng là 5.5.36. Với phiên bản MySQL này thì không hỗ trợ bảng mã utf8mb4_unicode_520_ci nhưng có hỗ trợ bảng mã utf8mb4_unicode_ci.

Vậy làm cách nào để bạn import database sử dụng bảng mã utf8mb4_unicode_520_ci lên hosting đang chạy phiên bản MySQL 5.5.36?

Ta sẽ có 2 cách:

• Cách 1: Báo lại với nhà cung cấp dịch vụ của bạn yêu cầu họ nâng cấp phiên bản MySQL lên phiên bản 5.6 (phiên bản này có hỗ trợ bảng mã utf8mb4_unicode_520_ci)
• Cách 2: Chuyển đổi bảng mã utf8mb4_unicode_520_ci về các bảng mã mà phiên bản MySQL hiện tại bạn đang dùng có hỗ trợ.

Ở đây chúng ta sẽ không bàn đến cách 1, Kỹ thuật sẽ hướng dẫn các bạn làm cách 2.

Với cách 2, đầu tiên bạn sẽ cần cài đặt Notepad++ để mở file database lên thì mình mới có thể chỉnh sửa được bảng mã. Tải về file cài đặt Notepad++ tại đây.

Sau khi đã tải về và cài đặt Notepad++ trên máy tính cá nhân, bạn tiến hành mở file database lên bằng cách click chuột phải vào file và chọn Edit with Notepad++.

Mở file lên xong, bạn sẽ tìm đến một bảng (table) gần nhất sẽ thấy bảng đó dùng bảng mã utf8mb4_unicode_520_ci.

Giờ ta sẽ đổi toàn bộ bảng mã utf8mb4_unicode_520_ci thành utf8mb4_unicode_ci bằng cách dùng tính năng Replace của Notepad++.

Bạn nhấn tổ hợp phim Ctrl+H hoặc là chọn Search > Replace như hình dưới.

Có một toolbox sẽ xuất hiện giữa màn hình, bạn sẽ nhập utf8mb4_unicode_520_ci vào ô Find what, nhập utf8mb4_unicode_ci vào ô Replace with, sau đó nhấn Replace All.

Tiến hành lưu lại file này và import database lại là thành công.

Nếu các bạn gặp phải lỗi `

1273 - Unknown collation: 'utf8mb4_unicode_ci' hoặc lỗi `You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' thì đó là do phiên bản MySQL hiện tại không hỗ trợ, bạn nên đổi về lại utf8_unicode_ci với cách như trên nhé.

(Exceeds 500VELO) 433 The content of the error register of the Z axis exceeded =32767. Or the velocity command value of the DA converter is out of the range of +8191~ – 8192. Incorrect settings will cause this alarm 434 The resolver/inductosyn position detecting system of Z axis is trouble 435 A feed rate exceeding 511875 detection units/sec was commanded in the Z axis. An incorrect setting of CMR causes this error 436 Z axis pulse coder position feedback is abnormal. (Disconnection alarm) 440 The content of the error register of the 4TH axis is larger than the value allowed while the machine is stopped 441 The content of the error register of the 4TH axis is larger than the value allowed while the machine is moving 442 Drift in 4TH axis is excessive. (Exceeds 500VELO) 443 The content of the error register of the 4THaxis exceeded =32767. Or the velocity command value of the DA converter is out of the range of +8191~ – 8192. Incorrect settings will cause this alarm 444 The resolver/inductosyn position detecting system of the 4TH axis is trouble 600 Data transferring error took place in the connection unit or in PC-model C 601 Slave relay was turned off. (Connections among unit, MDI/DPL (MDI/CRT) and master PCB are trouble. Also in another case change connection unit) 602 PC program has not yet been loaded 603 The correspondence between NC and PC is incorrect or interrupted. Change power sequence control PCB or master PCB 604 No hold is effective to PC-model B side MPU 605 A system error has occurred in PC-model B side MPU 606 RAM/ROM parity has occurred in PC-model B side MPU 607 Data transferring error took place in Fanuc MDI & CRT. Overheat alarm 700 Overheat of the master PCB 701 Overheat of the PCB for 4TH axis 702 Overheat of DC motor for X, Y, Z axis 703 Overheat of DC motor for 4TH axis. Errors on memory 900 Fault in bubble device. (Fault of input signal for bubble device) 901 Fault in bubble device. 902 Fault in bubble device. (Page size error, undefined command) 903 Fault in bubble device. (Transfer missing, page size over) 904 Fault in Fanuc bubble device. (Parity error) 905 Fault in bubble device.

Background Edit Alarm

Alarm Code Type Description of Alarm/Error ???? BP/S alarm BP/S alarm occurs in the same number as the P/S alarm that occurs in ordinary program edit. 140 BP/S alarm It was attempted to select or delete in the program being selected in the foreground. (Note)

Note: Alarm in background edit is displayed in the key input line of the background edit screen instead of the ordinary alarm screen and is resettable by any of the MDI key operation.
