Java中SQLServer中文字段如何处理和查询？

我们平常库表字段一般都是英文的，标准也是这样，如果碰到中文的应该如何处理呢？库表如下

先把实体类改成属性字段改成英文

@ApiModelProperty(value = "付款方名称")
    @TableField("付款方名称")
    private String payName;

    @ApiModelProperty(value = "付款条件")
    @TableField("付款条件")
    private String paymentClause;
	
	//其他太长不贴了哈

自写SQL语句，对中文字段取别名，as 成实体类属性（付款方名称 as payName）

where跟的属性还是数据库的字段名

<select id="selectKeyAccountByCompanyCodeAndPayCode" parameterType="string" resultType="FinCommercialOnestopshop001Keyaccount">
        select ID as id, [Index] as newIndex, 付款方代码 as payCode, 付款方名称 as payName, KAorEC as kaOrEc,
               [BU(By Management)] as bu, CompanyCode as companyCode,
               Company as company, 付款条件 as payClause, 城市 as city,
               KACustomerGroup as kaCustomerGroup, 销售经理 as salesManager,
               销售负责人 as directoSales, POA账龄 as poaBookAge
        from Fin_Commercial_OneStopShop_001_KeyAccount
        where
            CompanyCode = #{companyCode}
        and 付款方代码 = #{payCode};
    </select>

Mapper方法

FinCommercialOnestopshop001Keyaccount selectKeyAccountByCompanyCodeAndPayCode(@Param("companyCode") String companyCode, @Param("payCode") String payCode);

问题：为什么where后面不能跟别名

sqlserver查询执行顺序是如下

1. FROM JOIN ON
2. WHERE ♥
3. GROUP BY
4. HAVING
5. SELECT DISTINCT TOP() ♥
6. ORDER BY

可以看到，在where执行的时候，还未执行select，别名也就还没生效，而order by的时候select已经执行，所以已经存在 最后，还是建议用英文配合驼峰命名哈~
