[Bug] [flinkx-connector-oracle] sink data duplication

### Search before asking

- [X] I had searched in the [issues](https://github.com/DTStack/chunjun/issues) and found no similar issues.

### What happened

I use oracle-x as sink,and the flinksql is "SELECT ROUND(actor_id,0) as round_id,actor_bio,actor_chName FROM table_a",but finally the result is beyond expectation.

### What you expected to happen

The result of sink should be like this.

### How to reproduce

The flinksql is "SELECT ROUND(actor_id,0) as round_id,actor_bio,actor_chName FROM table_a",I put the results into a new table(table_b),and then execute the sinksql
"INSERT INTO `table_c` SELECT * FROM `table_b` ".
chunjun version is 1.14_beta.
flink version is 1.14.4.
