我可以通过提及定价层来创建 Azure Sql 数据库。

我正在尝试为数据库设置内存和 DTU。

我找不到正确的 Api，这是我尝试过的

PUT :    https://management.azure.com/subscriptions/<subscription-ID>/resourceGroups/<Resource-group-Name>/providers/Microsoft.Sql/servers/<Server-name>/databases/<Database-name>/?api-version=2014-04-01

请求正文：

 {
                "location": "East Asia",
                "properties": {
                    "edition": "Premium",
                    "collation":"SQL_Latin1_General_CP1_CI_AS",
                "sampleName": "blank database",
                "serviceTierAdvisors":[
                    {
                        "maxSizeInGB":"150",
                        "maxDtu":"500"
                    }   
                    ]
                }   
    }

我也没有收到正确的错误消息，任何人都可以指导我在数据库级别设置 DTU 的参数吗？

谁能指导我在数据库级别设置 DTU 的参数？

正确的 DTU 参数应该是requestedServiceObjectiveName。它的类型是枚举。您可以为此属性设置以下值。

Basic, 
S0, S1, S2, S3
P1, P2, P4, P6, P11, P15
System, System2
ElasticPool

请检查相应的 DTU 值如下。

Basic(5DTU), 
S0(10DTU), S1(20DTU), S2(50DTU), S3(100DTU)
P1(125DTU), P2(250DTU), P4(500DTU), P6(1000DTU), P11(1750DTU), P15(4000DTU)
System, System2
ElasticPool

您需要使用 API 来更新数据库，如本文所述。

例如：

{
    "parameters": {
        "subscriptionId": "00000000-1111-2222-3333-444444444444",

            }
        },
        "202": {}

}

在上面的示例中，我从标准 S0 缩小到基本层。

希望这可以帮助。

这是我所做的，它可以增加实例和 DTU。我必须进行试验才能使其正常工作，但找不到专门提到 DTU 的可靠文档：

我得到我的不记名令牌，然后调用这个方法来增加或减少 dtus。请注意对 GetUpdateSettingsJson() 的调用返回以下两个 Json 字符串，具体取决于我是增加还是减少 DTU / 实例大小： 增加 JSON：“{”sku”：{“name”：“Premium”，“tier”：“Premium ","capacity": 250} }" 减少 JSON : "{"sku": {"name": "Standard","tier":"Standard","capacity": 50} }"

private static async Task<string> UpdateDatabaseSettings()
    {
        using (HttpClient client = new HttpClient())
        {
            var updateDtuEndpoint = String.Format(@"https://management.azure.com/subscriptions/{0}/resourceGroups/{1}/providers/Microsoft.Sql/servers/{2}/databases/{3}?api-version=2017-10-01-preview",
                subscriptionId,
                databaseResourceGroup,
                databaseServer,
                databaseName
                );
            var accept = "application/json; charset=utf-8";

            client.DefaultRequestHeaders.Add("Accept", accept) ;
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue ("Bearer", bearerToken);

            //string queryParameters = String.Format(@"resource=https%3A%2F%2Fgraph.microsoft.com%2F&client_id={0}&grant_type=client_credentials&client_secret={1}", clientId, clientSecret);

            string jsonUpdateSetting = GetUpdateSettingsJson();

            using (var response = await client.PatchAsync(updateDtuEndpoint, new StringContent(jsonUpdateSetting, Encoding.UTF8, "application/json")))
            {
                if (response.StatusCode == System.Net.HttpStatusCode.Accepted)
                {
                    WriteLine("Capacity Update is Processing");
                    return "Capacity Update is Processing";
                }
                else
                {
                    Environment.ExitCode = 1;
                    WriteLine("Capacity Update failed.");
                    return "Capacity Update failed. ";
                }
            }


        }
    }

EXTRA：上面的这个方法只是把请求放进去，下面的方法被调用直到它可以确认改变是有效的。上面的方法只请求更改。该方法仅检查 RequestServiceObject = CurrentServiceObject（它不确认 DTU）。

private static async Task<bool> CheckDatabaseSettng()
    {
        using (HttpClient client = new HttpClient())
        {
            var checkDatabaseSettings = String.Format(@"https://management.azure.com/subscriptions/{0}/resourceGroups/{1}/providers/Microsoft.Sql/servers/{2}/databases/{3}?api-version=2017-10-01-preview",
                subscriptionId,
                databaseResourceGroup,
                databaseServer,
                databaseName
                );
            var accept = "application/json; charset=utf-8";

            client.DefaultRequestHeaders.Add("Accept", accept);
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", bearerToken);

            using (var response = await client.GetAsync(checkDatabaseSettings))
            {
                if (response.StatusCode == System.Net.HttpStatusCode.OK)
                {
                    var jsonresult = JObject.Parse(await response.Content.ReadAsStringAsync());
                    var jsonProperties = jsonresult["properties"];
                    if (jsonProperties == null)
                    {
                        throw new Exception("Could not find properties that are supposed to be returned in this call.");
                    }
                    var currentServiceObject = (string)jsonProperties["currentServiceObjectiveName"];
                    var requestedServiceObject = (string)jsonProperties["requestedServiceObjectiveName"];

                    string msg = string.Format("currentServiceObjectiveName = {0}; requestedServiceObjectiveName = {1}", currentServiceObject, requestedServiceObject);
                    WriteLine(msg);
                    if (currentServiceObject == requestedServiceObject)
                    {
                        return true;
                    }
                }
            }
        }

        return false;
    }

希望这可以帮助某人节省比我花在上面的时间更多的时间。

步骤 1：您需要在 azure 门户上创建 clientId、Token 和 clientSecret。使用本教程（有很多只是令人困惑）这个作品。如何获取令牌、客户端 ID 和客户端密码

Step2 : 接下来需要选择是使用其余 API 还是 SDK。我更喜欢 SDK，但这取决于你（你不需要弄清楚所有 json 值都在使用 SDK）。第 3 步假设您选择了 SDK。

要安装 SDK 的先决条件，您需要以下 nuget 包：

Install-Package Microsoft.Azure.Management.Fluent
Install-Package Microsoft.Azure.Management.ResourceManager.Fluent

对于 SQL，您需要以下内容：

Microsoft.Azure.Management.Sql.Fluent

您需要步骤 1 中的令牌进行身份验证。

Step3：接下来看这个例子如何使用SDK——很好看如何应用。 Azure SQL SDK

最后：这是一个代码片段，一旦您拥有以上所有内容 - 出色地完成了这项工作。

  string tenantId = "9596ecae-xxxxxxx";
  string clientAppId= "51c28b54-xxxxxxxxx";
  string secret = "@w6.Quv--your secret";

  credentials = SdkContext.AzureCredentialsFactory
           .FromServicePrincipal(clientAppId,
           secret,
           tenantId,
           AzureEnvironment.AzureGlobalCloud);

 var azure = Microsoft.Azure.Management.Fluent.Azure
            .Configure()
            .Authenticate(credentials)
            .WithDefaultSubscription();

 var database = azure.SqlServers
        .GetById("/subscriptions/<your specific>/resourceGroups/<your specific>/providers/Microsoft.Sql/servers/<your specific>")
        .Databases.GetById("/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Sql/servers/xxx/databases/xxx");

 var result = database.Update()
            .WithEdition(DatabaseEditions.Standard)
            .WithServiceObjective(ServiceObjectiveName.S0) <-- CHANGE LEVEL OF DB.
            .Apply();

SQL 和 DB 字符串名称的提示和帮助：获取正确的字符串来替换上面的代码是很棘手的。一个快捷方式是先调用 List，然后您可以调试并查看将什么放入 GetById 函数中，您可以先调用它并查看结果：

 azure.SqlServers.List() <-- Debug this and you will see the full names of the Database Servers string names
 Then do azure.SqlServer.Databases.List() <-- an array of objects where you can get the string for the database name.

希望有所帮助 - 文档很糟糕。
