Question

我使用此步骤Oracle 10g - Write queries results to file来创建xml文件。所以这是我加载的

的sql脚本

c：＆gt; sqlplus -s username /password@database.domain.com＆lt; tmp.sql＆gt; output.txt的

  set pagesize 0;
    set serveroutput on
    set termout off       
    set verify off     
    set heading off    
    set long 999
    set lines 999
    SET FEEDBACK OFF
    SET HEAD OFF

    SELECT '<?xml version="1.0" encoding="UTF-8"?>' || chr(10) ||
           '<!--Sample XML file generated by XMLSpy v2010 rel. 2 (http://www.altova.com)-->' || chr(10) ||
           '<HarpeML_CBS_IMX_ExchangeRate_Flow  xsi:noNamespaceSchemaLocation="HarpeML_CBS_IMX_ExchangeRate(REF-IMX-1)_v0.0.00.xsd"  xmlns:harpeml="http://www.harpeml.com"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">'||chr(10)||

            FROM dual;
    SELECT '<ExchangeRates>'||chr(10)||'<ExchangeRate>'||chr(10)||

    SELECT  '<harpeml:baseCurrencyCode>'||abrev||'</harpeml:baseCurrencyCode>'  FROM(SELECT abrev FROM v_domaine where type = 'DEVISE' ORDER BY  dbms_random.normal)WHERE rownum = 1;
    SELECT 
            '<harpeml:counterCurrencyCode>'||abrev||'</harpeml:counterCurrencyCode>'FROM(SELECT  abrev FROM v_domaine where type = 'DEVISE' ORDER BY  dbms_random.normal)WHERE rownum = 1;
    SELECT 
            '<harpeml:startValidityDate>'||''||to_char(sysdate -  4,'DD/MM/YYYY')||''||'<harpeml:startValidityDate>'||chr(10)||
             '<harpeml:countryCode>'||abrev||'</harpeml:countryCode>'FROM(SELECT  abrev FROM v_domaine where type = 'pays' ORDER BY  dbms_random.normal)WHERE rownum = 1;   
    SELECT
            '<harpeml:exchangeRate>'||rpad ( imk.nextval, 3, '51' )||'</harpeml:exchangeRate>'||chr(10)||
            '<harpeml:appreciationOrDepreciationReport>'||'1'||'</harpeml:appreciationOrDepreciationReport>'||chr(10)||

            '</HarpeML_CBS_IMX_ExchangeRate_Flow>'
            from dual;
    /

结果如下：

有谁知道为什么最后一次出现两次？你能给出任何建议如何从输出文件中删除空行吗？

Answer 1

在SQL * Plus中，分号执行一个语句。斜线也是如此。

您已使用执行它们的;终止了每个选择。然后，您使用/终止了脚本，这会导致最后一个语句再次执行。

至于空行，这只是运行几个不同语句的工件。我不担心他们。当然XML并不关心。

Hawever这是一种生成XML文件的繁琐方式：Oracle拥有大量XML功能：you should learn to use them。

Answer 2

最后一个块出现两次，因为脚本末尾有一个/ - 这会再次执行上一个查询。

只需将/替换为退出，就应该解决这个问题。

如何格式化用sqlplus创建的输出文件？为什么其中一个输出块出现两次？
