Vladimir Ozerov commented on IGNITE-11331:
------------------------------------------
A lot of test failures observed. Root cause: parameter type might be important
when it is returned as a column. E.g. {{SELECT col_a, ? FROM tbl}}. Principal
places:
# {{GridSqlQuerySplitter#collectColumns}} - where types are collected and where
exception due to {{GridSqlType.UNKNOWN}} is thrown
# {{GridReduceQueryExecutor#createMergeTable}} - where collected types are used
> SQL: Remove unnecessary parameters binding

> URL: https://issues.apache.org/jira/browse/IGNITE-11331
> Project: Ignite
> Issue Type: Task
> Components: sql
> Reporter: Vladimir Ozerov
> Priority: Major
> Fix For: 2.8
>
> Time Spent: 10m
> Remaining Estimate: 0h

> See usages of {{H2Utils#bindParameters}}. Note that it is used both in SELECT
> and DML planners without any reason. Let's remove it from there.
> Be careful with splitter - we will have to pass or calculate parameters
> number there.
