工作中有一个需求，将五个字段大批量数据一次性插入到数据库中，考虑到效率问题，使用了Oracle批量插入，由于数据量很大，可能会超过15000条，在执行的过程中出现了如题的异常，后来经过查阅资料，才明白这是占位符超过65535的原因，优化之后，每10000条插入一次，就没有这个问题了，具体报错信息如下：

### Cause: java.sql.SQLSyntaxErrorException: ORA-01745: invalid host/bind variable name

; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: ORA-01745: invalid host/bind variable name

xml文件如下：

<insert id="insertEducationCardBatch" parameterType="java.util.ArrayList">
        INSERT INTO TF_EDUCATION_CARD (CARD_NO,DEAL_DATE,DEAL_TIME,ROUTE_CODE,CAR_CODE)
        <foreach collection="list" item="item" index="index" separator="union all">
            SELECT #{item.cardNo},#{item.dealDate},#{item.dealTime},#{item.routeCode},#{item.carCode}
            FROM DUAL
        </foreach>
    </insert>
