使用springjdbc提示无效的sql语句

t-sql语句拼接的方式也用了，预处理的方式也用了，但是还是抛出如下异常(在Oracle数据端能查到插入的信息)：
在控制台打印的sql语句如下：
insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values (2,'个人','张三',88886,sysdate,'私人')

错误信息如下：
HTTP Status 500 - StatementCallback; bad SQL grammar [insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values (2,'个人','张三',88886,sysdate,'私人')]; nested exception is java.sql.SQLException: ORA-00900: 无效 SQL 语句

type Exception report

message StatementCallback; bad SQL grammar [insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values (2,'个人','张三',88886,sysdate,'私人')]; nested exception is java.sql.SQLException: ORA-00900: 无效 SQL 语句

exception

org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values (2,'个人','张三',88886,sysdate,'私人')]; nested exception is java.sql.SQLException: ORA-00900: 无效 SQL 语句

java 代码如下：
public class IJzxxDaoImpl implements IJzxxDao {
JdbcTemplate temp = new JdbcTemplate(DBUtil.getDs());

@Override
public int insertJzxx(Jzxx jz) {
    Integer dw_id = jz.getDw_id();
    String jz_type = jz.getJz_type();
    String jz_person = jz.getJz_person();
    Integer jz_money = jz.getJz_money();
    String jz_remark = jz.getJz_remark();
    //String sql = "insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values(?,?,?,?,sysdate,?)";
    String sql = "insert into jzxx(dw_id, jz_type, jz_person, jz_money, jz_date, jz_remark) values ("+dw_id+",'"+jz_type+"','"+jz_person+"',"+jz_money+",sysdate,'"+jz_remark+"')";
    System.out.println(sql);
    return temp.queryForInt(sql);
}

各种方法试过了还是搞不定，请大家帮帮忙，谢谢！

是我方法用错了，应该是update()方法而不是queryForInt().

仔细检查下每个字段的字段名，类型，是否少字段等
