> New PhoenixStatement API to return old row state in Atomic Updates
> ------------------------------------------------------------------
>
> Key: PHOENIX-7646
> URL: https://issues.apache.org/jira/browse/PHOENIX-7646
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Fix For: 5.3.0
>
>
> PHOENIX-7462, PHOENIX-7398, PHOENIX-7434, PHOENIX-7411 and PHOENIX-7630 Jiras
> have introduced support for PhoenixStatement to return ResultSet for updated
> new row version.
> The purpose of this Jira is to add support for returning the old row state
> (before update) in atomic update operations. This enhancement allows
> applications to retrieve the previous state of a row when performing
> conditional updates, enabling better audit trails.
> New API signature:
>
> {code:java}
> /**
> * Executes the given SQL statement similar to JDBC API executeUpdate() but
> also returns the
> * old row (before update) as Result object back to the client. This must be
> used with
> * auto-commit Connection. This makes the operation atomic.
> * If the row is successfully updated, return the old row (state before
> update), otherwise
> * if the row cannot be updated, return non-updated (old) row.
> *
> * @param sql The SQL DML statement, UPSERT or DELETE for Phoenix.
> * @return The pair of int and ResultSet, where int represents value 1 for
> successful row
> * update and 0 for non-successful row update, and ResultSet represents the
> old state of the
> * row.
> * @throws SQLException If the statement cannot be executed.
> */
> public Pair<Integer, ResultSet> executeAtomicUpdateReturnOldRow(String sql)
> throws SQLException {{code}
