--------------------------------------
Labels: ignite-3 (was: )
> Index alive after drop indexed column
> -------------------------------------
>
> Key: IGNITE-19305
> URL: https://issues.apache.org/jira/browse/IGNITE-19305
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 3.0
> Reporter: Alexander Belyak
> Priority: Major
> Labels: ignite-3
>
> In
> [documentation|https://ignite.apache.org/docs/3.0.0-beta/sql-reference/ddl#alter-table-if-exists-table-drop-column-if-exists-column1-column2-int]
> I see: "If the column was indexed, the index has to be dropped manually in
> advance by using the 'DROP INDEX' command." But it seems like an alpha
> version limitation.
> Unable to create index with the same name after dropping indexed column:
> {noformat}
> create table tindex(
> id int primary key,
> v1 int,
> v2 int);
> create index titest on tindex(v1, v2)
> alter table tindex drop column v1;
> create index titest on tindex(v2);{noformat}
> error:
> {noformat}
> [Code: 0, SQL State: 50000] Exception while executing query [query=create
> index titest on tindex(v2)]. Error message:IGN-SQL-17
> TraceId:5f61df67-cc61-4eb1-98be-3bbaa25a7c44 IGN-SQL-17
> TraceId:5f61df67-cc61-4eb1-98be-3bbaa25a7c44 Index already exists
> [name="PUBLIC"."TITEST"]{noformat}
> Expected behaviour:
> 1) index titest drop while dropping v1 columnd
> 2) index titest successfully created on the last DDL operation.
