Question

desc foo;打印所有列。

如何使其按字母顺序列出所有列

Answer 1

您可以使用information_schema，具体取决于您想要显示的内容。

类似的东西：

SELECT COLUMN_NAME, DATA_TYPE, IS_NULLABLE, COLUMN_DEFAULT
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE table_name = 'foo'
  AND table_schema = 'foo_schema'
  ORDER BY COLUMN_NAME;

Answer 2

ANSI INFORMATION_SCHEMA表(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
