select deptno,dname,dtype,dphone,dfax,ddescription,dupper,dcreatedate from dept where deptno=1
SQL语句在PLSQL下执行没有问题,但是放在程序中报下面的错。
if (rs.next()) {
dept.setDeptNo(rs.getInt("deptno"));
dept.setDeptName(rs.getString("dname"));
dept.setDeptType(rs.getString("dtype"));
dept.setDeptPhone(rs.getString("dphone"));
dept.setDeptFax(rs.getString("dfax"));
dept.setDeptDescription(rs.getString("ddescription"));
dept.setDupper(rs.getInt("dupper"));
dept.setDeptCreateDate(rs.getString("DCreateDate"));
}

把语句注释之后没有问题,后来经过排查,原来是对数据库中的date字段处理不当
把dept.setDeptCreateDate(rs.getString("DCreateDate"));改成dept.setDeptCreateDate(rs.getDate("DCreateDate").toString());以后问题随之解决。(PS:为了方便处理,我在程序中对日期用STRING类型处理,进行数据库插入,更新操作的时候用to_date()转换)
