ORA-00900：无效的SQL语句-NamedParameterJdbcTemplate

Question

我有此查询作为属性常量：

get.policy.list=SELECT policy FROM table WHERE policy IN (:policyList) AND state = :state

从jdbcTemplate获取和获取列表时，我得到：

引起原因：java.sql.SQLSyntaxErrorException：ORA-00900：无效的SQL语句

在try块的第一行。

@Override
    public List<MyVO> areValidPolicies(String state, List<String> policyList) {

        MapSqlParameterSource namedParameters = new MapSqlParameterSource().addValue("state", state)
                .addValue("policyList", policyList);

        List<MyVO> retrievedPolicyList = new ArrayList<MyVO>();

        try{
            retrievedPolicyList = myNamedJdbcTemplate.query("SELECT policy FROM table WHERE policy IN (:policyList) AND state = :state", namedParameters, new RowMapper<MyVO>() {

                        @Override
                        public MyVO mapRow(ResultSet rs, int rowNum) throws SQLException {
                            MyVO myVO = new MyVO();
                            MyVO.setPolicy(rs.getString("policy"));
                            return myVO;
                        }
                    });
        } catch (Exception ex){
            System.out.println(ex.getMessage());
            ex.printStackTrace();
        }

        retrievedPolicyList.stream().forEach(System.out::println);

        return retrievedPolicyList;
    }

请指导我在哪里弄错了。

table是SQL中的保留字。 我建议重命名该表以避免将来出现麻烦，但是如果不这样做，则可以使用双引号（ " ）对其进行转义：

 retrievedPolicyList = 
     myNamedJdbcTemplate.query("SELECT policy FROM \"table\" WHERE policy IN (:policyList) AND state = :state", namedParameters, new RowMapper<MyVO>() {
     // Here --------------------------------------^^-----^^
