Getting all the table details from Azure database to Databricks

Hello @Sandhya ,

Thanks for the question and using MS Q&A platform.

There are couple of methods to connect Azure SQL Database using Azure Databricks.

Method1: SQL databases using JDBC

The following Python examples cover some of the same tasks:

#Create the JDBC URL  
jdbcHostname = "<DBNAME.database.windows.net>"  
jdbcDatabase = "<DatabaseName>"  
jdbcPort = 1433  
jdbcUsername = "<UserName>"  
jdbcPassword = "<Password>"  
jdbcUrl = "jdbc:sqlserver://{0}:{1};database={2}".format(jdbcHostname, jdbcPort, jdbcDatabase)  
connectionProperties = {  
  "user" : jdbcUsername,  
  "password" : jdbcPassword,  
  "driver" : "com.microsoft.sqlserver.jdbc.SQLServerDriver"  
}  
#Push down a query to the database engine  
pushdown_query = "(select * from employees where emp_no < 10008) emp_alias"  
df = spark.read.jdbc(url=jdbcUrl, table=pushdown_query, properties=connectionProperties)  
display(df)  

Push down query to get the tables details from Azure SQL Database:

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

Method2: SQL databases using the Apache Spark Connector

There are two versions of the connector available through Maven, a 2.4.x compatible version and a 3.0.x compatible version. Both versions can be found here and can be imported using the coordinates below:

Prerequisites: You need to install the Apache Spark Connector.

Python code to Read from SQL Table using Apache Spark Connector:

server_name = "jdbc:sqlserver://<ServerName>.database.windows.net"  
database_name = "<DatabaseName>"  
url = server_name + ";" + "databaseName=" + database_name + ";"  
  
table_name = "<TableName>"  
username = "<UserName>"  
password = "<Password>" # Please specify password here  
  
jdbcDF = spark.read \  
        .format("com.microsoft.sqlserver.jdbc.spark") \  
        .option("url", url) \  
        .option("dbtable", table_name) \  
        .option("user", username) \  
        .option("password", password).load()  
display(jdbcDF)  

Hope this will help. Please let us know if any further queries.
