Ruslan Dautkhanov updated SPARK-21488:
--------------------------------------
Summary: Make saveAsTable() and createOrReplaceTempView() return dataframe
of created table/ created view (was: Make saveAsTable() return dataframe of
created table)
> Make saveAsTable() and createOrReplaceTempView() return dataframe of created
> table/ created view
> ------------------------------------------------------------------------------------------------
>
> Key: SPARK-21488
> URL: https://issues.apache.org/jira/browse/SPARK-21488
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, Spark Core, SQL
> Affects Versions: 2.2.0
> Reporter: Ruslan Dautkhanov
>
> It would be great to make saveAsTable() return dataframe of created table,
> so you could pipe result further as for example
> {code}
> (sqlc.sql('''
> SELECT ...
> FROM
> ''')
> .write.format("parquet").mode("overwrite")
> .saveAsTable('test.parquet_table')
> .createOrReplaceTempView('mv_table')
> )
> {code}
> ... Above code returns now expectedly:
> {noformat}
> AttributeError: 'NoneType' object has no attribute 'createOrReplaceTempView'
> {noformat}
> If this is implemented, we can skip a step like
> {code}
> sqlc.sql('SELECT * FROM
> test.parquet_table').createOrReplaceTempView('mv_table')
> {code}
> We have this pattern very frequently.
