    Operation Scenarios

    This document describes how to modify a table in the TcaplusDB Console. If you want to modify the structure definition of a table, you can do so by modifying the table under the condition that the new definition meets the TcaplusDB table modification rules.

    Prerequisites

    You have created a table. For more information, please see Creating Table.

    Directions

    1. Enter the Table List page and select the target table. Select More > Modify in the "Operation" column or select multiple tables and click Batch Modify at the top.
    2. In the "Modify" dialog box that pops up, upload or select a new table definition file and click Compare Difference.
      • The primary key field cannot be deleted.
      • The name and type of the primary key field cannot be modified.
      • You cannot add new primary key fields.
      • A general field marked as required cannot be deleted.
      • The name and type of fields with the same identifier cannot be modified.
      • A new general field should be named according to the naming convention.
    3. In the pop-up dialog box, you can view the comparison result. If your new table definition does not meet the TcaplusDB table modification rules, a prompt will be displayed.
    4. Click Preview in the "Comparison Preview" column to view the comparison between the new and old table structures.
    5. After confirming that everything is correct, click Confirm to submit your request to modify the table, and a prompt will be returned if the modification is successful.
