How can MyBatis query the CLOB field?

To query a CLOB field in MyBatis, you can follow these steps:

1. Convert to Character Large Object

<select id="getClobData" resultType="String" parameterType="int">
    SELECT TO_CLOB(clob_column) AS clob_data
    FROM your_table
    WHERE id = #{id}
</select>

1. Please choose one option.

String clobData = sqlSession.selectOne("getClobData", 1);

This way, you can query the value of a CLOB field and convert it to a string for processing.
