-----------------------------------------------------------------
[~xtern] The changes look good to me. But I can't understand why the behavior
is different for explicit and implicit transactions. The code changes don't
answer this question for me.

> Sql. Unexpected DML results with explicit TX and single column table.

> Key: IGNITE-19176
> URL: https://issues.apache.org/jira/browse/IGNITE-19176
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Pavel Pereslegin
> Assignee: Pavel Pereslegin
> Priority: Major
> Labels: ignite-3
> Time Spent: 50m
> Remaining Estimate: 0h
>
> When we try to insert values into a single column table using explicit
> transaction, those values are not visible in the same transaction.
> Example
> {code:java}
> create table test(id int primary key) // single column table
> {code}
> {code:java}
> // case 1
> start explicit tx
> insert into test values (0), (1)
> select count(*) from test // returns 0 instead of 2
> finish tx{code}
> {code:java}
> // case 2
> start explicit tx
> insert into test values (0), (1)
> commit tx
> start explicit tx
> select count(*) from test // returns 0 instead of 2
> finish tx{code}
> If we do this using implicit transaction - all works fine.
> If we add a column to the table, everything will work fine.
> Reproducer
> {code:java}
> @Test
> public void test() {
> sql("CREATE TABLE myTbl (id INT PRIMARY KEY) WITH REPLICAS=2,
> PARTITIONS=10");
> Ignite ignite = CLUSTER_NODES.get(0);
> ignite.transactions().runInTransaction(tx -> {
> sql(tx, "INSERT INTO myTbl VALUES (0), (1)");
> List<List<Object>> rows = sql(tx, "SELECT count(*) from myTbl");
> assertEquals(2L, rows.get(0).get(0));
> });
> } {code}
