问题描述

PMA有添加中央列的工具。据我所知,这是用于国外的限制。我有两个表: TableA TableB



TableA的结构: id_of_A name_of_A_value $ b $ TableB 的结构: id_of_B foreign_id_of_A ... foreign_id_of_A A表 id_of_A



在将新行插入 TableB 时,选择所需的 foreign_id_of_A 非常困难,因为只有值的 id_of_A 是可见的。中央的列可以帮助我解决这个问题吗?中央列如何工作?

解决方案

中央列

您可以按照您的要求将列添加/删除列表。中央列表中的这些列将可用于在为表创建新列或自行创建表时使用。您可以从中央列表中选择一个列,同时创建一个新列,这样可以避免再次写同一列定义,或者为相似列写入不同的名称。



允许使用这个功能:
$ b


  1. 设置 $ cfg ['Servers'] [$ i] ['pmadb'] 和phpMyAdmin配置
    存储


  2. 将表名放在 $ cfg ['Servers'] [$ i] ['central_columns'] (例如pma__central_columns)


可以通过将配置设置为false来禁用此功能。


PMA has the tools for adding the central columns. As far as I understand, it's used with foreign constraints. I have two tables: TableA and TableB.

Structure of TableA: id_of_A, name_of_A_value, ...

Structure of TableB: id_of_B, foreign_id_of_A,... and foreign constraint from foreign_id_of_A to A-table.id_of_A.

And it's very difficult to select needed foreign_id_of_A while insert new row into TableB because only value of id_of_A is visible. Could central columns help me with this problem? How central column works?

解决方案

Central Column

You can add/remove columns to the list as per your requirement. These columns in the central list will be available to use while you create a new column for a table or create a table itself. You can select a column from central list while creating a new column, it will save you from writing the same column definition over again or from writing different names for similar column.

To allow the usage of this functionality:

  1. set up $cfg['Servers'][$i]['pmadb'] and the phpMyAdmin configuration storage

  2. put the table name in $cfg['Servers'][$i]['central_columns'] (e.g. pma__central_columns)

This feature can be disabled by setting the configuration to false.
