【问题描述】：

我创建了一个生成此错误的脚本，但它仍然可以完美执行。我能做些什么来解决这个错误？我尝试了一些常见的修复方法，例如 SET SQLBLANKLINES ON，但没有奏效。

错误：SP2-0734：以“CONCAT('IN...”开头的未知命令 - 忽略行的其余部分。

这是产生错误的脚本部分：

PROMPT 'ENTER THE PERCENTAGE YOU WISH TO INCREASE THE PRICE BY: '
ACCEPT V_PCT_INCREASE NUMBER
PROMPT
PROMPT 'ENTER THE PRODUCT SEARCH CRITERIA: '
ACCEPT V_PRODUCT_DESC
PROMPT
PROMPT 'YOU HAVE CHOSEN TO UPDATE PRODUCTS WHOSE DESCRIPTION BEGINS WITH &V_PRODUCT_DESC WITH A PERCENTAGE INCREASE OF &V_PCT_INCREASE PERCENT.'
PROMPT
SET TERMOUT OFF;
SET VERIFY OFF;
SET SQLBLANKLINES ON;
SPOOL c:\runscripts\insert_prices.sql;
SELECT CONCAT('INSERT INTO TAR_TEMP_PRICE (PRODUCT_ID, START_DATE, LIST_PRICE, MIN_PRICE, END_DATE)
    VALUES (', P.PRODUCT_ID||', '''||PR.START_DATE||''', '||PR.LIST_PRICE * (1+(&V_PCT_INCREASE/100))||', '||PR.MIN_PRICE * (1+(&V_PCT_INCREASE/100))||', CURRENT_DATE'||');')
FROM TAR_PROD P
JOIN TAR_PRICE PR
ON P.PRODUCT_ID = PR.PRODUCT_ID
WHERE UPPER(P.DESCRIPTION) LIKE UPPER('&V_PRODUCT_DESC%');
SPOOL OFF;
SET FEEDBACK ON;
SET TERMOUT ON;
PROMPT 'A SCRIPT insert_prices.sql HAS BEEN CREATED AT c:\runscripts\insert_prices.sql'
PROMPT
PROMPT 'THE FOLLOWING PRODUCTS WERE ADDED TO THE INSERT SCRIPT WITH THE ADJUSTED PRICES: '
SELECT P.PRODUCT_ID, P.DESCRIPTION, PR.LIST_PRICE, PR.MIN_PRICE,
PR.LIST_PRICE * (1+(&V_PCT_INCREASE/100)) AS "ADJ_LIST_PRICE", 
PR.MIN_PRICE * (1+(&V_PCT_INCREASE/100)) AS "ADJ_MIN_PRICE"
FROM TAR_PROD P
JOIN TAR_PRICE PR
ON P.PRODUCT_ID = PR.PRODUCT_ID
WHERE UPPER(P.DESCRIPTION) LIKE UPPER('&V_PRODUCT_DESC%');
@C:\runscripts\insert_prices.sql
PROMPT 'INSERT SCRIPT IS COMPLETE.'
PROMPT 'SEE BELOW FOR RESULT VALIDATION.'
SELECT *
FROM TAR_TEMP_PRICE;
ROLLBACK;

它仍然有效，但我想抑制错误。

以上代码生成的插入语句：

CONCAT('INSERTINTOTAR_TEMP_PRICE(PRODUCT_ID,START_DATE,LIST_PRICE,MIN_PRICE,END_DATE)VALUES(',P.PRODUCT_ID||','''||PR.START_DATE||''','||PR.LIST_PRICE

INSERT INTO TAR_TEMP_PRICE (PRODUCT_ID, START_DATE, LIST_PRICE, MIN_PRICE, END_DATE)                                                                  
    VALUES (100861, '01-JAN-89', 43.68, 34.944, CURRENT_DATE);                                                                                           

INSERT INTO TAR_TEMP_PRICE (PRODUCT_ID, START_DATE, LIST_PRICE, MIN_PRICE, END_DATE)                                                                  
    VALUES (100870, '01-JAN-90', 3.136, 2.688, CURRENT_DATE);

    VALUES (100870, '01-JAN-89', 2.688, 2.128, CURRENT_DATE); 

由于某种原因，它从上面的代码中添加了部分选择语句。

这是输出：

'ENTER THE PERCENTAGE YOU WISH TO INCREASE THE PRICE BY: '
12

'ENTER THE PRODUCT SEARCH CRITERIA: '
DYN

'YOU HAVE CHOSEN TO UPDATE PRODUCTS WHOSE DESCRIPTION BEGINS WITH DYN WITH A PERCENTAGE INCREASE OF      12 PERCENT.'

【问题讨论】：

也许你的脚本有一些控制字符。你从 unix/windows 运行它？

我在 Windows 8 的 SQLPlus 上运行它。

您实际上在 INSERT 中形成了 SELECT ，但您的输出在此处显示为列？？

该输出用于验证。我添加了脚本的其余部分以显示假脱机后会发生什么。

你能显示文件“insert_prices.sql”的前几行吗？我想也许引号可能会弄乱 SQL 字符串 ...

【参考方案1】：

将此添加到您的 SQL*Plus 提示中。 (SET HEAD OFF)

SET TERMOUT OFF;
SET VERIFY OFF;
SET SQLBLANKLINES ON;
SET HEAD OFF /* This turns of the headers in result */
SET FEEDBACK OFF /* Turns off the result feedback */

问题是您的SELECT 的结果列具有以CONCAT(.. 开头的默认名称作为别名。

原来如此……

CONCAT('INSERTINTOTAR_TEMP_PRICE(PRODUCT_ID,START_DATE,LIST_PRICE,MIN_PRICE,END_DATE)VALUES(',P.PRODUCT_ID||','''||PR.START_DATE||''','||PR.LIST_PRICE
------------------------------------------------------------------------------------------------------------------------------------------------------

当您执行 INSERT 脚本时，甚至会与您的其他插入一起执行。所以，我们必须关闭标题。

我在阅读您的评论之前修复了它。我将 pagesize 设置为 0 并且它起作用了。您的解决方案也应该有效，因此我将其标记为答案。谢谢！
