Getting error on connecting to a local SQL Server database to databricks via JDBC connection

问题

Basically I'm trying to connect to a SQL Server database on my local machine from databricks using a JDBC connection. I'm following the procedure mentioned in the documentation as shown here on the databricks website.

I used the following code as mentioned on the website:

jdbcHostname = "localhost"
jdbcDatabase = "TestDB"
jdbcPort = "3306"

jdbcUrl = "jdbc:mysql://{0}:{1}/{2}".format(jdbcHostname, jdbcPort, jdbcDatabase)
connectionProperties = {
    "jdbcUsername" : "user1",
    "jdbcPassword" : "pass1",
    "driver" : "com.microsoft.sqlserver.jdbc.SQLServerDriver"
     }

pushdown_query = "SELECT * FROM dbo.customer"
df = spark.read.jdbc(url=jdbcUrl, table=pushdown_query,properties=connectionProperties)
display(df)

But I'm getting this error

IllegalArgumentException: requirement failed: The driver could not open a JDBC connection. Check the URL: jdbc:mysql://localhost:3306/TestDB

Can anyone explain why is it happening? How can I fix this error?

回答1:

Usually 3306 port used for mysql databases.

Try with 1433 port for Sql server databases.

in jdbc url use sqlserver instead of mysql jdbcUrl = "jdbc:sqlserver://{0}:{1};databaseName={2}"

---

Example Jdbc url:

jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks
