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
I have checked these pages : https://stackoverflow.com/questions/3397121/how-to-show-row-numbers-in-postgresql-query
This is my query:
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
this is the error:
ERROR: syntax error at or near "over" LINE 1: select row_number() over (ORDER BY cgcode_odc_mapping_id)as
