> Sql. Infer dynamic parameter types for scripts.
> -----------------------------------------------
>
> Key: IGNITE-21097
> URL: https://issues.apache.org/jira/browse/IGNITE-21097
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Maksim Zhuravkov
> Priority: Minor
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> After https://issues.apache.org/jira/browse/IGNITE-20778 was resolved it is
> now possible to infer types of dynamic parameters for a single SQL statement.
> Since SQL engine also provides API to execute SQL scripts, it should be
> possible to extend dynamic parameter type inference to scripts as well.
> There some limitations on supported statement types in SQL scripts to support
> type inference of dynamic parameters - type inference won't work if a script
> includes a DDL statement (because DDL statements can make add/remove/change
> type columns, thus making type inference without DDL interpretation
> impossible).
> So if a script contains any DDL statement a process of inference of dynamic
> parameter type should report an error, indicating that type inference cannot
> be perform in presence of DDL statements.
