Question

我创建了一个生成此错误的脚本，但它仍然可以完美执行。我该怎么做才能解决此错误？我尝试了一些常见的修补程序，比如SET SQLBLANKLINES ON，但它没有用。

错误：SP2-0734：未知命令开始“CONCAT（'IN ...” - 忽略其余行。

这是生成错误的脚本的一部分：

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，但我希望能够抑制错误。

上面代码生成的insert语句：

由于某种原因，它正在从上面的代码中添加部分select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.'

SP2-0734: unknown command beginning "CONCAT('IN..." - rest of line ignored.

Answer 1

将此添加到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SELECT的结果列的默认名称以CONCAT(..作为别名开头。

所以就像..

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，甚至会与其他插件一起执行。所以，我们必须关闭标题。

如何使用CONCAT在SQL Plus中解决SP2-0734？
