what is the unique id of informix temp table?

I create a temp table which consist of several table with UNION ALL statement like here below. I want later map this table to the entity for repository in spring. With other words I wanna map temp table to entity in spring jpa or hibernate.
select * from name UNION ALL
select * from soft where id >3
into temp namesoft_tmp
I tried the following.
select * from namesoft_tmp
but i can't see what is the column which can point me to the conclusion that this is primary key.
What is the unique id(primary key) of table namesoft_tmp?
How can i add auto generated id to temp table?
How can i excute select statement based on unique id?**

In general, the result of a UNION ALL query does not have a primary key; there is no guarantee that there are not duplicate rows in the result set.
Imagine a table describing the table of elements — called elements.
SELECT * FROM elements WHERE atomic_number < 10
UNION ALL
SELECT * FROM elements WHERE symbol MATCHES '[A-F]*'
INTO TEMP union_all;
Here, the elements Boron (B), Carbon (C), Beryllium (Be) and Fluorine (F) are all listed twice.
However, you can use:
SELECT ROWID, * FROM union_all ORDER BY atomic_number;
to get a unique identifier, the ROWID, in the result set. Note that this unique identifier is unique at any given time, but is not guaranteed to be stable. If you delete rows and add them again, the ROWID of the replaced rows may be different from before. But the ROWID will be unique until you edit the table.

Spark Java API, Dataset Manipulation?

I'm new spark Java API. My dataset contains two columns (account, Lib) . I want to display accounts having differents lib. In fact my dataset is something like this.
ds1
+---------+------------+
| account| Lib |
+---------+------------+
| 222222 | bbbb |
| 222222 | bbbb |
| 222222 | bbbb |
| | |
| 333333 | aaaa |
| 333333 | bbbb |
| 333333 | cccc |
| | |
| 444444 | dddd |
| 444444 | dddd |
| 444444 | dddd |
| | |
| 555555 | vvvv |
| 555555 | hhhh |
| 555555 | vvvv |
I want to get ds2 like this:
+---------+------------+
| account| Lib |
+---------+------------+
| | |
| 333333 | aaaa |
| 333333 | bbbb |
| 333333 | cccc |
| | |
| 555555 | vvvv |
| 555555 | hhhh |

If groups are small you can use window functions:
import org.apache.spark.sql.functions._
import org.apache.spark.sql.expressions.Window
df
.withColumn("cnt", approx_count_distinct("Lib").over(Window.partitionBy("account")).alias("cnt"))
.where(col("cnt") > 1)
If groups are large:
df.join(
df
.groupBy("account")
.agg(countDistinct("Lib").alias("cnt")).where(col("cnt") > 1),
Seq("account"),
"leftsemi"
)

Threads Running Indefinitely While Parsing Addresses

For the past year, I've been developing a system that uses ANTLR for parsing. Now in UAT and running on a Tomcat server, we are regularly having performance issues due to threads running indefinitely while attempting to parse certain street addresses. For instance, we've found some running over 7.5 hours before we caught and killed them. When enough get in this state, they will tie up all the cores and cause every request sent to the system to timeout. Although we've upgraded to ANTLR 4.7 (previously 4.5.3) and reduced the occurrence frequency through grammar changes over the past few weeks, we still haven't been able to fully resolve the issue. Below is the log for one of these threads as well as the grammar. Does anyone have an idea of the cause?

if (board.gameEnd() || depth == 0)
{
return null;
}
//Tree oldTree = new Tree(board);
for (int i = 0; i < potBoards.size() - 1; i++)
{
Tree newTree = new Tree(potBoards.get(i));
createTree(newTree, !isHuman, depth - 1);

Hi there. I'm trying to make a gameTree that will be handled by minimax in the future. I think the error either happened in the AddChild function or the potentialMoves? The potentialMoves returns all potential moves a player or computer can make. For example in Othello a player can either go

for the first turn. The potential moves does not permanently change the board that is being played on. It returns an ArrayList.
I have this in my main:
Tree gameTree = new Tree(boardOthello);
Tree pickTree = gameTree.createTree(gameTree, true, 2);
Does the addChild() function look ok or is there something else I'm missing in my code?
