Hello:
I have a select statement like so:
<select id="getExemption"
parameterType="freebird.exemption.business.QueryCondition"
resultMap="exemptionResultMap" >
select exemption.id
,exemption.account_id,exemption.customer_id,exemption.customer_name,exemption.address1,exemption.address2,exemption.city,
exemption.state,exemption.country_code,exemption.zipcode,exemption.federal_id_type,exemption.federal_id,exemption.phone_number,exemption.email,
exemption.active,exemption_locations.country_code,exemption_locations.state_code,exemption_locations.reason_code,
exemption_locations.permit_id,exemption_locations.start_date,
exemption_locations.end_date
from exemption left join exemption_locations on exemption.id
=exemption_locations.exemption_id
where exemption.account_id=#{accountId,jdbcType=VARCHAR}
<if test="exemptionId!=null">
and exemption.id=#{exemptionId,jdbcType=INTEGER}
</if>
<if test="customerId!=null">
and exemption.customer_id=#{customerId,jdbcType=VARCHAR}
</if>
and rownum <= #{maxCount} order by id
</select>
I can't connect to my Oracle DB through SqlSessionFactory.openSession(),a
NullPointerExeption object was thrown out.
When I remove the above red words,it works.Why?I think my select
statement is correct,because I tested in Oracle.
I also tried 'and rownum<=1000',but still failed.
