Question

I need to get for each company_name and node_name the first text (the row who has the lowest row_id) from table T_TBL_DATA. Something like:

SELECT company_name, node_name, [text]
FROM T_TBL_DATA
GROUP BY company_name, node_name
WHERE the selected [text] is from the row with the smallest row_id within each group

Any idea?

Answer 1

select company_id, node_id, [text]
from t_tbl_data
where row_id in
(
    select min(row_id)
    from t_tbl_data
    group by company_id, node_id
)
