How can I write data from a Snowpark DataFrame to a Snowflake table?

There are a few ways to write data from a Snowpark DataFrame to a Snowflake table.

  • Using the writeTable() method: This method is available in the Snowpark API for each supported programming language. It takes a few parameters, such as the name of the table and the database in which the table resides.
  • Using the save() method: This method is also available in the Snowpark API for each supported programming language. It takes a few parameters, such as the path to the file where the data will be saved.
  • Using the Snowpark SparkSession: If you are using Snowpark with Spark, you can write data from a Snowpark DataFrame to a Snowflake table by using the Snowpark SparkSession. This class provides a number of convenience methods for writing data to Snowflake tables.

Here is an example of how to write data from a Snowpark DataFrame to a Snowflake table using the writeTable() method in Python:

Python

from snowflake.snowpark import Session
from snowflake.snowpark import DataFrame

session = Session.builder().account("myaccount").user("myuser").password("mypassword").build()

df = session.readTable("mytable", "mydatabase")
df.writeTable("mynewtable", "mydatabase")

from snowflake.snowpark import Session
from snowflake.snowpark import DataFrame

session = Session.builder().account("myaccount").user("myuser").password("mypassword").build()

df = session.readTable("mytable", "mydatabase")
df.save("/tmp/mynewtable")

Here is an example of how to write data from a Snowpark DataFrame to a Snowflake table using the Snowpark SparkSession in Scala:

Scala

import com.snowflake.snowpark._
import com.snowflake.snowpark.spark._

val session = SnowparkSession.builder()
  .account("myaccount")
  .user("myuser")
  .password("mypassword")
  .build()

val df = session.readTable("mytable", "mydatabase")
df.writeTable("mynewtable", "mydatabase")

Use code with caution. 

Once you have written data to a Snowflake table, you can query the table using SQL or use it in other Snowpark DataFrames.
