Spark reading writing to SQL Database

The following blog post illustrates reading/writing to Fabric Warehouse from Spark notebook.

@https://community.fabric.microsoft.com/t5/Data-Engineering-Community-Blog/Spark-Connector-for-Fabric-Warehouse-Unified-Analytics/ba-p/4611309

 

Are there examples to read and write to SQL Database(preview) using Spark within Fabric notebook? Say even this (currently failing): 

 df.write.jdbc(...)

    Hi P_work 

     

    try this

     

    df.write.mode("append").option("mergeSchema", "true").synapsesql("DW1.Core.CustomerData")

      I believe the main issue was this:

      notebookutils.credentials.getToken("pbi")
       
      The examples provided were of little use.
       
      Also, ensuring using runtime 1.3 appeared to help.

    Here is how you connect to SQL DB from Fabric Notebook using SPN credentials

    host = ''
    database = ''
    sql_query = ''
    jdbc_url = f'jdbc:sqlserver://{host};database={database};authentication=ActiveDirectoryServicePrincipal;encrypt=true;trustServerCertificate=true;'
    db_properties = {
    "user": f"{client_id}",
    "password": f"{client_secret}",
    "driver": "com.microsoft.sqlserver.jdbc.SQLServerDriver"
    }
    #For Reading
    spark.read.jdbc(url=jdbc_url, table=f"({sql_query}) AS query_alias", properties=db_properties)
    #For Writing data
    df.write.jdbc(url=jdbc_url, table=table_name, mode=mode, properties=db_properties)
