mybatis:The content of elements must consist of well-formed character data or markup

今天写了一个SQL语句，放入工程

[sql] view
plaincopy





SELECT *   

FROM GR_EDUCATION_BACKGROUND   

WHERE SYSDATE - decode(eb_end_date, null, sysdate, EB_END_DATE) < 730  

报错，The content of elements must consist of well-formed character data or markup

经查mybatis不能有小于号，把代码更换成

[sql] view
plaincopy





SELECT *   

4000
FROM GR_EDUCATION_BACKGROUND   

WHERE 730 > SYSDATE - decode(eb_end_date, null, sysdate, EB_END_DATE)   

错误消失
