How to select row number in postgres.
I tried this:
select
row_number() over (ORDER BY cgcode_odc_mapping_id)as rownum,
cgcode_odc_mapping_id
from access_odc.access_odc_mapping_tb
order by cgcode_odc_mapping_id
and got this error:
ERROR: syntax error at or near "over" LINE 1: select row_number() over (ORDER BY cgcode_odc_mapping_id)as

this is the error:
ERROR: syntax error at or near "over" LINE 1: select row_number() over (ORDER BY cgcode_odc_mapping_id)as
