我收到以下错误：
org.apache.jasper.JasperException: An exception occurred processing JSP page /paging.jsp at line 67
64: String sqlPagination="SELECT SQL_CALC_FOUND_ROWS * FROM employee limit "+iPageNo+","+iShowRows+"";
65:
66: psPagination=conn.prepareStatement(sqlPagination);
67: rsPagination=psPagination.executeQuery();
68:
69: //// this will count total number of rows
70: String sqlRowCnt="SELECT FOUND_ROWS() as cnt";
造成这种情况的原因是什么？
