Re: Re: Does Table API connector, csv, has some option to ignore some columns

No, I did not mean.

I said 'Does Table API connector, CSV, has some option to ignore some columns in source file?'

Hi, did you mean `insert into table1 select col1, col2, col3 ... from table2`?

 

If this doesn't meet your requirement, what about using UDF to custom what you want in runtime.

I want to control what I insert in table not what I get from table.

Hi. 

 

In Flink SQL, you can select the column that you wants in the query. For example, you can use 

 

```

SELECT col_a, col_b FROM some_table;

```

 

Best,

For instance read only first, second, nine... but not the others?

 

Or any other trick?

CREATE TABLE some_table (
  some_id BIGINT,
  ...
) WITH (
 'format' = 'csv',
 ...
)
