> Support parameterized prepared statements in ExecuteSQL
> -------------------------------------------------------
>
> Key: NIFI-978
> URL: https://issues.apache.org/jira/browse/NIFI-978
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Daryl Teo
> Assignee: Matt Burgess
> Priority: Minor
>
> PutSQL and ExecuteSQL are highly inconsistent and leads to confusion.
> - PutSQL relies on FlowFile content to execute it's statement.
> - ExecuteSQL relies on SQL Select Command attribute
> - PutSQL supports parameterized statements through sql.args attributes
> - ExecuteSQL relies on Expression Language to insert dynamic properties
> The reliance on expression language for ExecuteSQL may also lead to potential
> SQL injection if one is not careful as it is a string replacement.
> Therefore in the interest of reliability and consistency I highly recommend
> that the SQL processors be standardised.
> Note: I prefer the sql command attribute for running SQL as opposed to the
> (lower visibility) content based command specification. Having the query
> attribute of ExecuteSQL, with the sql.args attributes of PutSQL would be a
> great improvement. If you support this, I will create a new issue in Jira.
