为什么Azure WebJob无法连接到Azure SQL,并说“存储帐户的类型不受支持,仅限Blob/ZRS”。支持的类型是“通用的”?

所以我有一个Azure Web应用,它是一个带有实体框架的ASP.NET MVC应用。它使用Azure SQL数据库。我需要定期(一天一次)对金融市场利率数字进行投票,并将其插入数据库。我为两个市场利率调查创建了两个WebJobs(一个需要在市场开放后运行,另一个是在市场关闭后运行),并安排了它们。

我无法理解。SQL Azure数据库是一个普通的数据库,有些表有blob列,但是没有MarketRates表。

string connectionString = "Copy of the the Azure SQL connection string";
SqlConnection sqlConnection = new SqlConnection(connectionString);

string selectStatement = "SELECT MAX(Id) FROM BlaBla.dbo.MarketRates";
SqlCommand selectCmd = new SqlCommand(selectStatement, sqlConnection);
sqlConnection.Open();
var id = (int)selectCmd.ExecuteScalar();
sqlConnection.Close();

string insertStatement = "INSERT INTO BlaBla.dbo.MarketRates(Id, Type, Rate, Date) " +
    "VALUES(@Id, @Type, @Rate, @Date)";
SqlCommand insertCmd = new SqlCommand(insertStatement, sqlConnection);

var now = DateTime.Now;
insertCmd.Parameters.Add("@Id", SqlDbType.Int);
insertCmd.Parameters.Add("@Type", SqlDbType.VarChar, 64);
insertCmd.Parameters.Add("@Rate", SqlDbType.Float);
insertCmd.Parameters.Add("@Date", SqlDbType.DateTime);
insertCmd.Parameters["@Id"].Value = id + 1;
insertCmd.Parameters["@Type"].Value = rateType;
insertCmd.Parameters["@Rate"].Value = rate;
insertCmd.Parameters["@Date"].Value = now.Date;

sqlConnection.Open();
insertCmd.ExecuteNonQuery();
sqlConnection.Close();

“存储帐户属于不支持的类型'Blob Only/ZRS'。支持的类型是“通用的”?

你好像在用 blob storage account 使用Azure webjob。请尝试将azurewebjobstorageconnection字符串更改为其他通用字符串 storage account 连接。

另外填充 AzureWebJobsDashboard AzureWebJobsStorage 连接字符串与通用存储帐户的连接字符串 app.settings 你的网络工作。
