Hi,
I've another use case for a possible if check:
- if the parameterType long it fails for the if check:
<select id="getMegaList" resultType="Mega" parameterType="long">
Select
id, descr, description from mega_t
<where>
<if test="id != -1">
id = #{id}
</if>
</where>
</select>
Thank you in advance,
Andreas

Sorry, I had a missunderstanding, it works this way:
...
<if test="id != -1">
and x.id = #{id}
</if>

Hi,
how can I deal with numeric class properties for dynamic sql in iBatis
3.x? In the older 2.x release there exist a `<isGreaterThan>' tag and
the user guide for 3.x only mentioned the <if> condition. For that, I
get a NumberFormatException:
Caused by: java.lang.NumberFormatException: For input string: "{0=null}"
The example looks like:
<select id="getSomeList" resultType="SomeClass"
parameterType="SomeConditionClass">
select
<include refid="someColumns"/>
from
hmm_t t, context_x x
where
t.id = x.id_hmm <if
test="#{id} != -1">
and x.id = #{id} </if>
</select>
Thank you in advance,
Andreas
