арифметическое исключение, числовое переполнение или усечение строки

я использую firebird в качестве базы данных и mybatis для управления данными, но когда я запускаю запрос с ключевым словом, длина которого больше 5, то происходят следующие ошибки:

### Cause: org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544569. Dynamic SQL Error
SQL error code = -303
arithmetic exception, numeric overflow, or string truncation
No message for code 335544914 found.

если длина меньше 6, она работает нормально. Я обновляю mybatis и firebird до последней версии, и результат тот же.

подробный sql, как показано ниже:

 select b.*, bt.type_no as "type.id" , bt.type_dsc "type.name", 
  bt.show "type.show", bt.del "type.del" 
from 
  book b,book_type bt 
where 
  b.type_no=bt.type_no and bt.del=0 
  and b.del=0 and b.type_no in (74) 
  and (( lower(title) like '%aaaaaaaaa%' ) or ( lower(content) like '%aaaaaaaaa%' )) 
order by bt.show desc,b.type_no,b.id 

с последующим журналом ошибок:

и mybatis в SQL defination:

 <select id="findByTypeTitleContent"  parameterType="map" resultMap="booknoteMap">
          select
             b.*,
             bt.type_no as "type.id" ,
             bt.type_dsc "type.name",
             bt.show "type.show",
             bt.del "type.del"
          from
               book b,book_type bt
          where
              b.type_no=bt.type_no
              and bt.del=0
              and b.del=0
              <if test="typeNos!=null">
                 and b.type_no in (
                  <foreach collection="typeNos" item="t" separator=",">
                      #{t.id}
                 </foreach>
                 )
             </if>

             <if test="keys!=null">
                  and ((
                 <foreach collection="keys" item="key"  separator="and" >
                         lower(title) like #{key}
                 </foreach>
                 ) or (
                  <foreach collection="keys" item="key"  separator="and" >
                         lower(content) like #{key}  
                 </foreach>
                 ))
            </if>
          <choose >
                 <when test="typeNo>0">
                     order by bt.show desc, b.id
                 </when>
                 <otherwise>
                     order by bt.show desc,b.type_no,b.id
                 </otherwise>
             </choose>
        </select>

Я сделал больше тестов и обнаружил,что заголовок нравится, независимо от того, как долго ключевое слово, контент, например, вызывает ошибку, когда длина больше 5. столбец заголовка-varchar (100), содержимое -Blob sub_type 1, но в любом случае это совершенно нормально в консоли sql, что делает меня настолько запутанным, ошибка просто происходит при запуске в java

какие идеи? Давно не виделись.
