PHP myAdmin - Change Field Order (Move Up Or Down)

问题:

How do I change the order of my table fields without deleting the field and re-inserting it, using PHP myAdmin?

回答1:

ALTER TABLE `table_name` MODIFY `column_you_want_to_move` DATATYPE AFTER `column`

DATATYPE is something like DATETIME or VARCHAR(20) ..etc

回答2:

If you have phpMyAdmin 4.0.0+, you can use the phpMyAdmin Feature under Structure:

回答3:

Something like this will help

ALTER TABLE Person MODIFY COLUMN last_name VARCHAR(50) AFTER first_name;

This will move last_name right after first_name in order.

From the Aforementioned Source:

If you decide to change the order of table columns anyway, you can do so as follows:

1. Create a new table with the columns in the new order.

2. Execute this statement:

   mysql> INSERT INTO new_table -> SELECT columns-in-new-order FROM old_table;

3. Drop or rename old_table.

4. Rename the new table to the original name:

   mysql> ALTER TABLE new_table RENAME old_table;

回答5:

Since version 4.0, phpMyAdmin has a "Move columns" dialog in Structure, that permits you to graphically move columns in the structure.

回答6:

alter table table_name modify column col_name type after col_name

回答7:

Another alternative:

CREATE new_table SELECT columns-in-new-order FROM old_table;

回答8:

if you have MySQL Workbench you can easily reorder columns using mouse, graphically.

Just connect to your database, select your table and after right click, alter table and then drag columns to reorder them.

It's simple. Just go to PHPmyadmin, click on your database, then click table. Then click on structure. Below the table look for the button, "Move columns". Click and order the columns the way you want.
