>             Project: Ignite
>          Issue Type: Bug
>          Components: sql

> 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}
>
