Question

我有这个表和示例数据，我想在文件中假脱机。我不确定什么是正确的方法或语法。我从互联网上尝试了几种方法，但无法得到正确的答案。

CREATE TABLE RoomType
(
RoomType Varchar2(25),
RoomTypeDesc Varchar2(50)
);

INSERT INTO RoomType VALUES ('STD', 'Standard Room');
INSERT INTO RoomType VALUES ('Business', 'Business Class');

使用您喜欢的编辑器（如vi）将您的命令保存在一个文件中，在您喜欢的路径中（让我们将/home/oracle/scripts）作为.sql文件：

[oracle@DoonieDB scripts]$ vi RoomTypes.sql
set term[out] off
set feed[back] off
col RoomType format a25
col RoomTypeDesc format a25
spool /home/oracle/scripts/RoomTypes.txt
select * from RoomType;
spool off;

其中col设置用于限制列的长度以使它们保持单行。

连接到您的相关架构，并通过添加.sql符号前缀来@，并使用格式化信息获取RoomTypes.txt文件：

[oracle@DoonieDB scripts]$ pwd
/home/oracle/scripts
[oracle@DoonieDB scripts]$ sqlplus hotels/myKey
