是否可以查询MySQL数据库以按字母顺序获取表的列名?我知道
SHOW COLUMNS `table_name`;
或
DESCRIBE `table_name`;
将为我提供表中列的列表(以及其他信息),但是可以更改查询以便按字母顺序对列进行排序。添加ORDER BY'Field'不起作用,它给出了语法错误。

ANSI INFORMATION_SCHEMA tables (in this case, INFORMATION_SCHEMA.COLUMNS)在MySQL中提供了更大的灵活性:
SELECT c.column_name
FROM INFORMATION_SCHEMA.COLUMNS c
WHERE c.table_name = 'tbl_name'
-- AND c.table_schema = 'db_name'
ORDER BY c.column_name

在我使用group by column name
select c.COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS c
where c.TABLE_NAME = `'tbl_name'`
group by c.column_name
order by c.column_name

如果您需要更多详细信息,请在下面查询非常方便:
SELECT COLUMN_NAME as 'Field',
COLUMN_TYPE as 'Type',
IS_NULLABLE as 'Null',
COLUMN_KEY as 'Key',
COLUMN_DEFAULT as 'Default',
EXTRA as 'Extra'
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'my table' and
TABLE_SCHEMA = 'my database'
add ordering
order by Type; --
