Ef執行Sql查詢
阿新 • • 發佈：2020-07-27
1、無引數查詢
varmodel = db.Database.SqlQuery<UserInfo>("select* from UserInfoes ").ToList();
2、有參查詢
varmodel = db.Database.SqlQuery<UserInfo>("select* from UserInfoes where id=@ID ",newSqlParameter("@ID",id)).ToList();
3、結合linq查詢
varmodel = (frompindb.userinfo.SqlQuery("select * from UserInfoes where id=@ID",newSqlParameter("@ID", 1))selectp).ToList();
4：EF原始查詢單獨表
model = db.userinfo.OrderByDescending(a => a.ID).Skip(10 * (當前頁 - 1)).Take(10).ToList();
5，EF 執行儲存過程或delete 刪除語句
SqlParameter[] para =newSqlParameter[] {
newSqlParameter("@ID",id)
};
db.Database.ExecuteSqlCommand("delete UserInfoes where id=@ID", para);
儲存過程 刪除，有幾個引數，儲存後面要帶幾個引數以逗號分隔
SqlParameter[] para =newSqlParameter[] {
newSqlParameter("@ID",id)
};
db.Database.ExecuteSqlCommand("sp_Userinfos_deleteByID @ID", para);
