Hi,
I've written a N + 1 query in Ibatis such a way that it will return the
nested results as below :
Customer - First object
DealFacility - An array list of objects within Customer
Facility - An array list of objects within
DealFacility
LoanInfo - An array list of objects within
Facility
The Customer object is having a 'strCustomerId' as an attribute. I need
to use this 'strCustomerId' in the WHERE clause of the query used for
populating 'LoanInfo' (<select id="getFacilityLoans" ) i.e, 3 level
below the Customer, in addition to 'Facility' class above.
I've placed my Login.xml query below.
<resultMap id="customersResults"
class="com.ge.cf.myaccounts.domain.Customer">
<result property="strCustomerId"
column="CUSTOMER_CODE"/>
<result property="strCustomerName"
column="CUSTOMER_NAME"/>
<result property="alDealFacilities"
column="CUSTOMER_CODE" select="Login.getDealFacilities"/>
</resultMap>
<select id="getCustomerDetails" resultMap="customersResults"
parameterClass="com.ge.cf.myaccounts.domain.Customer">
SELECT CUSTOMER_CODE,CUSTOMER_NAME
FROM STG_INTM_CUSTOMER_INFO
WHERE CUSTOMER_CODE=#strCustomerId#
</select>
..
..
..
<select id="getDealFacilities" resultMap="dealFacilityResults"
parameterClass="java.lang.String"> (selecting Facilities here)
<select id="getFacilities" resultMap="facilityResults"
parameterClass="java.lang.String"> (Selecting facility loans here)
<select id="getFacilityLoans" resultMap="facilityLoanResults"
parameterClass="java.lang.String"> (In this query, I need to use the
"strCustomerId" from the first Customer object within the N+1 query.
Any suggestion would be much helpful.
Regards,
Tamil
