<if test= "birthdate lt '20-10-2000'">
it works but is there a better way which mybatis documentation approves?
I am looking for a query where i can use either internal query returned value or direct SQL in when test= in Mybatis.
<foreach item="ID"
index="index"
collection="selectionIds"
separator=";">
UPDATE TABLE_1 SET
ACT_IND ='N', upd_by = 1234
WHERE SLCT_ID = #{ID}
AND rem= select REM from TABLE_1 where SLCT_ID=#{ID}
<choose>
<when test="rem == 3">
AND Bbsid=#{nsid}
</when>
<otherwise>
AND asid=#{asid}
</otherwise>
</choose>
</foreach>
From the above query, how can i get the rem value and use in when condition.
Thanks
I have a MyBatis query that looks like this:
<if test="userIdList != null and userIdList > 0">
AND galleries.id IN (
SELECT gallery_id
FROM gallery_users
WHERE gallery_id IN (
<foreach collection="userIdList" item="item" separator="," open="(" close=")">
#{item}
</foreach>
)
GROUP BY gallery_id HAVING COUNT(gallery_id) = ???
)
</if>
That part I'm stuck on is getting the collection size which will be dynamic. So how can I get the collection size so that I can properly fill in the '???' value?
You can invoke the Collection#size() method using OGNL expression. i.e.
GROUP BY gallery_id HAVING COUNT(gallery_id) = ${userIdList.size}
Note that #{userIdList.size} won't work here because the expression in #{} is parsed by MyBatis' internal expression parser and not by OGNL.
I have query written in Oracle in MyBatis Mapper xml file like below:
<select id="getUserList" resultMap="userListResult" parameterType="org.user.UserNumber>
select * from user
WHERE (1=1)
<if test="num != null">AND rownum <= #{num}</if>
</select>
I need to make this Postgres Compliant. So, converted as below:
<select id="getUserList" resultMap="userListResult" parameterType="org.user.UserNumber>
select * from user
WHERE (1=1)
<if test="num != null">AND LIMIT #{num}</if>
</select>
But it is not working and throwing exception:
PSQLException: ERROR: syntax error at or near \"LIMIT\"\n
Can anyone help me please how to replace rownum here in Postgres?
Okay, I am trying to generate sql for a Map<String,List<String>>, I am having a nested foreach statements to generate sql. This is my mybatis xml mapper file:
<select id="UserScaleResult.listAccordingToScaleBrief" resultType="java.util.Map">
select distinct uu.id as uid, uu.fullname, ucn.card_number,
uu.mobile_number
from
<include refid="UserScaleResult.baseCondition.from" />
<include refid="UserScaleResult.UserType.from"/>
<include refid="UserScaleResult.listAccordingToScale.from"/>
<include refid="UserScaleResult.baseConditions.where" />
<include refid="UserScaleResult.UserType.where" />
<include refid="UserScaleResult.listAccordingToScale.where" />
limit #{offset}, #{pageSize}
</select>
<sql id="UserScaleResult.listAccordingToScale.where">
<if test="#Ognl#isNotEmpty(type)">
and musr.type = #{type}
</if>
<if
test="#Ognl#isNotEmpty(createTimeBegin) and #Ognl#isNotEmpty(createTimeEnd)">
and musr.create_time between #{createTimeBegin} and
#{createTimeEnd};
</if>
<if test="#Ognl#isNotEmpty(missionId)">
and musr.mission_id = #{missionId}
</if>
<if test="#Ognl#isNotEmpty(scaleId)">
and musr.scale_id = #{scaleId}
</if>
<if test="#Ognl#isNotEmpty(sdl)">
and (
<foreach collection="sdl.entrySet()" item="item" open="(" separator=") or (" close=")">
tsrdl.dimension_id = #{item.key}
<if test="#Ognl#isNotEmpty(item.value)">
and
<foreach collection="item.value" item="iitem" open="(" separator=" or " close=")">
tsrdl.level_id = #{iitem}
</foreach>
</if>
</foreach>
)
</if>
</sql>
The log shows the #{iitem} are all null when it put it down to sql, although the number of parameters are correct:

EDIT:
Just did some experiment, when I substitute the '#' sign in #{iitem} with '$', the value appears and the sql gets parameters all good.
We need to use ${dataBaseTable} instead of #. The difference is that # is used for PreparedStatement substitution. $ is for direct String substitution.
Replace your #{iitem} with ${iitem}
....
<foreach collection="item.value" item="iitem" open="(" separator=" or " close=")">
tsrdl.level_id = ${iitem}
</foreach>
....
