如何从 Oracle 中的表中获取列名?
我需要查询数据库以获取列名,不要与表中的数据混淆.例如,如果我有一个名为 EVENT_LOG
的表,其中包含 eventID
、eventType
、eventDesc
和 eventTime
,然后我想从查询中检索这些字段名称,而不是其他任何东西.
I need to query the database to get the column names, not to be confused with data in the table. For example, if I have a table named EVENT_LOG
that contains eventID
, eventType
, eventDesc
, and eventTime
, then I would want to retrieve those field names from the query and nothing else.
我发现如何做到这一点:
I found how to do this in:
- Microsoft SQL Server
- MySQL
- PostgreSQL
但我需要知道:如何在 Oracle 中做到这一点?
But I need to know: how can this be done in Oracle?
推荐答案
可以查询USER_TAB_COLUMNS表的表列元数据.
You can query the USER_TAB_COLUMNS table for table column metadata.
SELECT table_name, column_name, data_type, data_length
FROM USER_TAB_COLUMNS
WHERE table_name = 'MYTABLE'
