New features

    This release includes APIs for registering named permanent, named session-temporary, and anonymous session-temporary stored procedures. It also includes APIs for calling stored procedures, both registered in Snowflake and to run locally.

    For related APIs, refer to the following.

  • Session.tableFunction function now also works with DataFrame columns.

    Previously, the Session.tableFunction method only supported literal function arguments. With this release, you can specify DataFrame columns from a single frame as an argument. For more information, refer to tableFunction in the reference documentation.

    Note that all DataFrame columns used as arguments should come from the same DataFrame.

Version 1.7.0 (January 7, 2023)

Compatible Snowflake release: 7.0.x

New features

  • Added methods that support PARTITION BY and ORDER By when joining a DataFrame with the output of a UDTF.

Improvements

  • Made more predictable the result when column heads are duplicated across joined DataFrames. As of this release, duplicated column names will be presented as found in the DataFrames that were joined. Previously, aliases were used for duplicated column heads. Aliases will still be used for duplicated column heads when the result of a join is saved to a table or cached – you should deduplicate before saving or caching.

Behavior changes

  • Changed from int to long the return value data type of methods that return a count of rows merged, updated, or deleted. For these methods, see the MergeResult, UpdateResult, and DeleteResult types.
