找到问题所在sql语句

<select id="findList" resultType="EduBasisGrade">
		SELECT 
			<include refid="eduBasisGradeColumns"/>
		FROM edu_basis_grade a
		<include refid="eduBasisGradeJoins"/>
		<where>
			a.state_flag = #{DEL_FLAG_NORMAL} AND a.school_id = #{schoolId}
			<if test="gradeName != null and gradeName != ''">
				AND a.grade_name LIKE 
					<if test="dbName == 'oracle'">'%'||#{gradeName}||'%'</if>
					<if test="dbName == 'mssql'">'%'+#{gradeName}+'%'</if>
					<if test="dbName == 'mysql'">concat('%',#{gradeName},'%')</if>
			</if>
			<if test="gradeYear != null and gradeYear != ''">
				AND a.grade_year LIKE 
					<if test="dbName == 'oracle'">'%'||#{gradeYear}||'%'</if>
					<if test="dbName == 'mssql'">'%'+#{gradeYear}+'%'</if>
					<if test="dbName == 'mysql'">concat('%',#{gradeYear},'%')</if>
			</if>
		</where>
		<choose>
			<when test="page !=null and page.orderBy != null and page.orderBy != ''">
				ORDER BY ${page.orderBy}
			</when>
			<otherwise>
				ORDER BY a.update_date DESC
			</otherwise>
		</choose>
	</select>

其中

a.school_id = #{schoolId}

school_id未赋值导致报错
