Question

我正在使用shell脚本调用Oracle sqlplus，我想将查询结果导出到sql文件。

这个请求给了我很多价值：

SELECT * FROM CUST_TABLE WHERE  CUST_CITY = 'San Fran';

我希望我的脚本生成如下的sql文件：

evariste@Unix-Server$cat first_query_result.sql

INSERT INTO CUST_TABLE (COLUMN_1, COLUMN_2, ....)
VALUES (CUST1_COLUMN_1, CUST1_COLUMN_2, ...);
INSERT INTO CUST_TABLE (COLUMN_1, COLUMN_2, ....)
VALUES (CUST2_COLUMN_1, CUST2_COLUMN_2, ...);
INSERT INTO CUST_TABLE (COLUMN_1, COLUMN_2, ....)
VALUES (CUST3_COLUMN_1, CUST3_COLUMN_2, ...);

关于如何在我的脚本中执行该操作的任何想法（我在Oracle和SQL中有一些背景知识）？

这些方面的一些东西，也许是：

sqlplus -silent uid/pw@db <<+EOF
set heading off
set feedback off
set pagesize 0
set linesize 32000
set trimspool on
set termout off
set echo off
set verify off
set sqlblanklines off
spool somefile.sql
WITH cust_table AS 
(SELECT 1 id, 'San Francisco' city, 'C1V1' col1, 'C2V1' col2 FROM dual
 UNION ALL SELECT 2, 'Los Angeles', 'C1V2', 'C2V2' FROM dual
 UNION ALL SELECT 3, 'San Jose', 'C1V3', 'C2V3' FROM dual
 UNION ALL SELECT 4, 'San Francisco', 'C1V4', 'C2V4' FROM dual)
SELECT 'INSERT INTO cust_table (id, city, col1, col2)'||CHR(10)||'VALUES ('||
       id||','''||city||''','''||col1||''','''||col2||''');'
  FROM cust_table
 WHERE city = 'San Francisco';
quit;
+EOF

这导致文件somefile.sql包含以下内容：

INSERT INTO cust_table (id, city, col1, col2)
VALUES (1,'San Francisco','C1V1','C2V1');
INSERT INTO cust_table (id, city, col1, col2)
VALUES (4,'San Francisco','C1V4','C2V4');

作为查询请求的结果生成Oracle SQL文件
