零代码、低代码对于软件市场的影响:需要入坑的小白一定要看哦_无极低码的博客-CSDN博客
无极低代码平台是作者自己定义的一套解析规则,相对mybatis来说更轻量和简单,只要会写sql基本不需要任何额外的知识就可以进行数据接口的开发。
无极低码采用的是md文件格式,当然改为txt也没问题,重要的是内容
下面是一个包含了单表增删改查的功能,是自动生成的,可以满足多条件检索,多参数修改等,先看一下内容我们稍后解释

这里面我们可以看到是一个单表数据查询,需要输出的字段我们可以自己定义,多条件组合通过@+字段方式动态拼接,而@后的这个参数是暴露给前端的字段可以随便写,如果前端在调用接口的时候传了参数就会动态拼接进去,比如:select id ,name ,phone ,pass ,headpic ,create_time createTime,org_code orgCode,user_type userType from d_base_user where 1=1
@byid
and id =#byid#
前端接口调用过程中传递了参数byid,sql的最终执行结果就是:
select id ,name ,phone ,pass ,headpic ,create_time createTime,org_code orgCode,user_type userType from d_base_user where 1=1 and id=1
前端接口调用过程中传递了参数byid和byheadpic,sql的最终执行结果就是:
select id ,name ,phone ,pass ,headpic ,create_time createTime,org_code orgCode,user_type userType from d_base_user where 1=1 and id=1 and byheadpic='http//www.baidu.com/img.png'
数据类型
数字类型:and id =#byid#
字符串类型:and byheadpic=’#byheadpic#‘
in条件
@byIn_id
and id in(#byIn_id#)
like模糊条件
@bychecks
and checks like '%#bychecks#%'
时间段条件
@bystartmodifiedTime&&byendmodifiedTime
and modified_time between '#bystartmodifiedTime#' and '#byendmodifiedTime#'
insert
===
insert ignore into d_code_manager(code_num,simple_name,name,modified_time,size)
VALUES(#codeNum#,'#simpleName#','@#name#',NOW(),#size#);
##之间表示数字
'##'之间表示字符串
'@##'之间的字符串表示该字段不允许为空
就这点规则了,我想10分钟应该可以学会了吧
