如何从 Oracle 中的表中获取列名?

2021-12-05 00:00:00 sql database oracle

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 eventIDeventTypeeventDesceventTime,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'
