Mule：JDBC选择不适用于＃[variable]值

Question

I have this piece of code in my configuration where I am using a variable as part of the 'WHERE' clause to retrieve some values from a database.

    <logger message="ZIP CODE:#[zipcode] " level="INFO" doc:name="Logger"></logger>
    <jdbc-ee:outbound-endpoint exchange-pattern="request-response" queryTimeout="-1" 
     connector-ref="Database" doc:name="Get Information" queryKey="Select MKT">
    <jdbc-ee:query key="Select MKT" value="SELECT PRIMARY,SECONDARY FROM MKT 
     WHERE  MRZIP=#[zipcode]"/>
    </jdbc-ee:outbound-endpoint> 
    <logger message="VALUES Selected for MKTREL : #[message.payload]" 
    level="INFO" doc:name="logger"></logger> 

This line does not give the output as in there are no results coming back from the DB.

    ZIP CODE:59718 
    INFO  2014-02-11 14:58:19,057 [[salesorderservice].SalesOrderProcess_pickOut.stage1.02]     
    INFO  2014-02-11 14:58:19,093 [[salesorderservice].SalesOrderProcess_pickOut.stage1.02]  
    : VALUES Selected for MKTREL : []

However when I hardcode the value I get the correct result:

    <jdbc-ee:query key="Select MKT" value="SELECT PRIMARY,SECONDARY FROM MKT 
     WHERE  MRZIP=59718"/>

Output is:

    VALUES Selected for MKTREL : [{PRIMARY=76, SECONDARY=45}]

Am I missing something here?

Answer 1

Try setting the zipcode variable to Integer, or use WHERE MRZIP=#[Integer.parseInt(zipcode)] . I guess you have an issue with your database not liking quoted integers.

Answer 2

Try to cast value in query to number by using DB specific function.

eg ORACLE/PLSQL and TO_NUMBER function:

<jdbc-ee:query
    key="Select MKT"
    value="SELECT PRIMARY,SECONDARY FROM MKT WHERE  MRZIP=TO_NUMBER(#[zipcode])"
/>
