Read/Write Data from Sql Database using JDBC

jdbc connect to database

Define the JDBC URL and connection properties

jdbc_url = "jdbc:sqlserver://<server>:<port>;databaseName=<database>"

connection_properties = {
    "user": "<username>",
    "password": "<password>",
    "driver": "com.microsoft.sqlserver.jdbc.SQLServerDriver"
}

Read data from the SQL database

df = spark.read.jdbc(url=jdbc_url, table="", properties=connection_properties)

Write data to the SQL database

df.write.jdbc(url=jdbc_url, table="", mode="overwrite", properties=connection_properties)

example

# Parameters
server_name = "myserver.database.windows.net"
port = "1433"
database_name = "mydatabase"
table_name = "mytable"
username = "myusername"
password = "mypassword"

# Construct the JDBC URL
jdbc_url = f"jdbc:sqlserver://{server_name}:{port};databaseName={database_name}"
connection_properties = {
    "user": username,
    "password": password,
    "driver": "com.microsoft.sqlserver.jdbc.SQLServerDriver"
}

# Read data from the SQL database
df = spark.read.jdbc(url=jdbc_url, table=table_name, properties=connection_properties)

# Perform any transformations on df if needed

# Write data to the SQL database
df.write.jdbc(url=jdbc_url, table=table_name, mode="overwrite", properties=connection_properties)
