json字段查询

[mansai]

表达式树没有对应的json字段查询 https://freesql.net/guide/expression-function.html

例如下图ExtraProperties字段为json存储，json里对应的字段为Cpu,Ram,Price三个动态字段

declare @jsontable table(userName varchar(50),ExtraProperties varchar(max)) insert into @jsontable values('name1','{"Cpu":"Intel I7","Ram":"32GB","Price":"1999"}') insert into @jsontable values('name2','{"Cpu":"Intel I3","Ram":"16GB","Price":"1699"}') select * from @jsontable

例如要模糊搜索内存为32的数据行对应sql句语如下 select * from @jsontable where JSON_VALUE(ExtraProperties, N'$.Ram') LIKE '%32%'

能否加入到SqlExt里面

不支持动态传参，jsonMap类型为Dictionary<string, object?>

[FreeSql.DataAnnotations.JsonMap] public Dictionary<string, object?> ExtraProperties { get => base.ExtraProperties; protected set => base.ExtraProperties = value; }

var sql=_repository.FreeSql.Queryable().Where(t => t.ExtraProperties["Cpu"]== "32GB").ToSql();

动态这种情况，需要定义类似 SqlExt.xxx 解析
