使用[此链接] [1]设置我的Databricks笔记本以连接到Azure SQL。我正在尝试在笔记本中运行SQL查询。但是得到错误

输入以下内容后：

%scala 

Class.forName("com.databricks.spark.sqldw.DefaultSource")

import org.apache.spark.sql.functions._ import org.apache.spark.sql.{DataFrame, SQLContext}

spark.conf.set(
  "fs.azure.account.key.<your-storage-account-name>.blob.core.windows.net",
  "<your-storage-account-access-key>")

    // Load data from a SQL DW query
   val df: DataFrame = spark.read
  .format("com.databricks.spark.sqldw")
  .option("url", "jdbc:sqlserver://xxxxx.database.windows.net:1433")
  .option("tempDir", "wasbs://xxxxx@xxxxx.blob.core.windows.net/https:")
  .option("forwardSparkAzureStorageCredentials", "true")
  .option("query", "select * from xxxx.xxxx")
  .load()
