mssql 数据库连接方法封装
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";

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![] |
// 执行 sql 语句
let data: Vec<serde_json::Value> = 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
// 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<Feedback> = 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<Feedback> = ms_run_vec(&mut client, sql_f).await.unwrap();
// 获取计数
let res_count: Vec<MssqlQuickCount> = ms_run_vec(&mut client, mscount!("for_test", {})).await.unwrap();
// 自定义查寻
let list: Vec<serde_json::Value> =
ms_run_vec(&mut client, "select distinct type_v3 from dishes".to_owned()).await.unwrap();
组合查寻
通过 Sql 包裹
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);
