### mssql 数据库连接方法封装 ```rust use mssql_quick::{ ms_run_vec, mscount, msdel, msfind, msget, msset, mssetmany, msupdate, msupdatemany, EncryptionLevel, MssqlQuick, MssqlQuickSet, }; const MSSQL_URL: &str = "server=tcp:localhost,1433;user=SA;password=ji83laa;database=dev_db;IntegratedSecurity=true;TrustServerCertificate=true"; let mut client = MssqlQuick::new(MSSQL_URL, EncryptionLevel::NotSupported) .await .unwrap() .client; ``` ### mssql sql执行 | 运行sql | 说明 | | ---------- | ---------------------------------------------- | | ms_run_vec | 执行sql,返回vec类型数据,无数据则返回`vec![]` | ```rust // 执行 sql 语句 let data: Vec = ms_run_vec(&mut conn, sql).unwrap(); ``` ### sql快捷生成 | sql快捷生成方法 | 说明 | | --------------- | ----------------------- | | mscount | 返回计数的sql | | msdel | 删除一条数据的sql | | msdelmany | 批量删除数据的sql | | msfind | 查寻数据的sql | | msget | 查寻一条数据的sql | | msset | 新增一条数据的sql | | mssetmany | 批量新增数据的sql | | msupdate | 更新一条数据的sql | | msupdatemany | 批量更新数据的sql | | 自定义 | 可以直接写自己的sql语句 | 以下内容,则为常用sql的快捷方法 ```rust // 新增一条数据 ms_run_vec(&mut client, msset!("for_test", { "content": "ADFaadf", "uid": 9, "info": Some("a"), })).await.unwrap(); // 删除一条数据 ms_run_vec(&mut client, msdel!("for_test", 50)).await.unwrap(); // 更新一条数据 ms_run_vec(&mut client, msupdate!("for_test", 56, { "content": "更新后的内容", "tatol": Some(200), })).await.unwrap(); // 批量 新增数据 mssetmany!("for_test", vec![ Item {uid: 1, content: "批量更新00adf"}, Item {uid: 2, content: "2342341"}, Item {uid: 3, content: "mmmmm"}, ]) ms_run_vec(&mut client, msql).await.unwrap(); // 批量 更新数据 let sql = msupdatemany!("for_test", "uid", vec![ Item {uid: 1, content: "批量更新00adf"}, Item {uid: 2, content: "2342341"}, ]) ms_run_vec(&mut client, sql).await.unwrap(); // 获取一条数据 let sql1 = msget!("for_test", 33, "id, content as cc"); #[derive(Serialize, Deserialize, Debug)] struct Feedback { id: u64, cc: String } let res_get: Vec = ms_run_vec(&mut client, sql1).await.unwrap(); // 查寻数据 let sql_f = msfind!("for_test", { p0: ["uid", ">", 330], r: "p0", select: "id,content as cc", }); let res_find: Vec = ms_run_vec(&mut client, sql_f).await.unwrap(); // 获取计数 let res_count: Vec = ms_run_vec(&mut client, mscount!("for_test", {})).await.unwrap(); // 自定义查寻 let list: Vec = ms_run_vec(&mut client, "select distinct type_v3 from dishes".to_owned()).await.unwrap(); ``` ### 组合查寻 通过 Sql 包裹 ```rust use mssql_quick::Sql; let sql1 = msfind!("Hospital", { p0: ["HospitalName", "like", "信息%"], r: "p0", select: "HospitalId", }); let sql2 = mscount!("DataBase..Patient", { // 对其他库的表查寻 p0: ["InvestigationId", "=", Sql("Investigation.InvestigationId")], r: "p0", }); let sql = msfind!("Investigation", { j1: ["HospitalId", "inner", "Hospital.HospitalId"], p0: ["HospitalId", "in", Sql(sql1)], p1: ["InvType", "=", "门诊"], r: "p0 && p1", select: "InvestigationId, HospitalId, (".to_string() + sql2.as_str() + ") as patient_count", // 如果自己写sql语句,要注意sql注入 }); println!("sql>>>>> {} \n", sql); ```
