Question

我的查询在这里，我需要选择哪个选项作为mule应用程序运行。

 <http:inbound-endpoint exchange-pattern="request-response"  host="myhost" port="${port}" path="offcycle" doc:name="HTTP"/>
        <set-variable variableName="companies" value="${companies.torun}" doc:name="Variable"/>
        <db:insert config-ref="hrlites_Configuration" doc:name="Database" >
            <db:dynamic-query>
insert into PAYRNUM (PAYGROUP,T2_PAYROLL_NUM,SEPCHK,NAME....)

        select T2_SOURCE_COMPANY,T2_PAYGROUP_TYPE,...
        from   (
        SELECT T2_SOURCE_COMPANY,T2_PAYGROUP_TYPE,PAY_END_DT,...
        FROM   CHK_STG2
        WHERE  COMPANY = #[flowVars.companies]
          AND  T2_PAYGROUP_TYPE = 'ZZ'
          AND  PAY_END_DT =  '30/JUN/2013'
        ORDER BY PAY_END_DT,
              CASE WHEN T2_INVOICE_NBR LIKE 'IN%' then 1
                   WHEN T2_INVOICE_NBR LIKE 'CM%' then 2                   
                   ELSE 3
              END
        ) a,
        (
        select t2_invoice_nbr, OFF_CYCLE, CASE When b.OFF_CYCLE ='N' THEN 0
                    ELSE rownum
                    END as T2_PAYROLL_NUM
        from   (
                select distinct t2_invoice_nbr, OFF_CYCLE
                from   (
                        SELECT T2_INVOICE_NBR,...
                        FROM   PS_T2_INV_CHK_STG2
                        WHERE  COMPANY = #[flowVars.companies]
                          AND  T2_PAYGROUP_TYPE = 'ZZ'
                          AND  PAY_END_DT =  '30/JUN/2013'
                        ORDER BY PAY_END_DT,
                            CASE WHEN T2_INVOICE_NBR LIKE 'IN%' then 1
                                  WHEN T2_INVOICE_NBR LIKE 'CM%' then 2                                 
                                  ELSE 3
                            END
                      )
               ) b
        ) bb
    where a.t2_invoice_nbr = bb.t2_invoice_nbr      
    ORDER BY PAY_END_DT,
        CASE WHEN T2_INVOICE_NBR LIKE 'IN%' then 1            
             ELSE 5
        END;
        </db:dynamic-query>
        </db:insert>        
    </flow>

1）如果运行查询，它在db中执行正常。但如果我在骡子流中运行，我会收到以下错误：

我选择了type作为参数而不是Dynamic，但没有用。

2）如何在控制台中显示执行的查询，以便我知道传递的参数和最终查询。

Answer 1

我看到您在查询中使用了flowvar。您是在查询执行之前定义公司flowvar吗？如果不是，您的查询就像

.. 公司= 和 ...

这将是invalida。

您可以使用Mule调试器并在数据库消息处理器中添加断点，以查看属性和变量的值。

如果在执行查询后想要记录查询结果，可以尝试添加一个对象到字符串的转换器，然后添加一个带有＃[payload]表达式的记录器。

mule基于条件执行查询
