问题描述
我需要找到特定表中的列,这没问题:
I need to find the columns in a specific table, which is no problem:
SHOW COLUMNS FROM tablename LIKE '%ColumnPrefix%';
但是我需要知道它们将以什么顺序返回,最好选择按字母顺序升序排列结果.我没有使用ORDER BY
的运气.
But I need to know what order they will be returned, preferably by choosing to order the results ascending alphabetically. I have had no luck with using ORDER BY
.
有什么想法吗?
推荐答案
You can query the table INFORMATION_SCHEMA.COLUMNS
to get the information that SHOW COLUMNS
gives you, plus it allows you to use ORDER BY or any other SQL syntax you might want to use:
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'tablename'
AND column_name LIKE 'ColumnPrefix%'
ORDER BY column_name
