mybatis插入时,当插入clob类型时报错,ORA-01461:仅能绑定要插入LONG列的LONG值。
mapper文件SQL如下
<insert id="addDutyPost" parameterType="dp">
insert into sds_duty_post(id,title,content,creator,create_date)
select SEQ_SDS_DUTY_POST.NEXTVAL,#{title,jdbcType=VARCHAR},#{content,jdbcType=CLOB},#{creator,jdbcType=VARCHAR},sysdate
from dual where not exists(select 'x' from sds_duty_post where title=#{title})
</insert>
这个SQL在长度<4000时,工作正常;大于4000,会提示ORA-01461.
修改SQL
<select id="selPostByTitle" parameterType="string" resultType="dp">
select id as postid,title,content,creator,create_date,updator,update_date from sds_duty_post where title=#{value}
</select>
<insert id="addDutyPost" parameterType="dp">
insert into sds_duty_post(id,title,content,creator,create_date)
values (SEQ_SDS_DUTY_POST.NEXTVAL,#{title,jdbcType=VARCHAR},#{content,jdbcType=CLOB},#{creator,jdbcType=VARCHAR},sysdate)
</insert>
或者
<select id="selPostByTitle" parameterType="string" resultType="dp">
select id as postid,title,content,creator,create_date,updator,update_date from sds_duty_post where title=#{value}
</select>
<insert id="addDutyPost" parameterType="dp">
declare
cntnt clob:=#content#
begin
insert into sds_duty_post(id,title,content,creator,create_date)
values (SEQ_SDS_DUTY_POST.NEXTVAL,#{title},cntnt,#{creator},sysdate);
end;
</insert>
