Question

SELECT [Column1] FROM VIEW1 WHERE ROW_NUMBER = 5;

gives an error:

Msg 207, Level 16, State 1, Line 2 Invalid column name ‘ROW_NUMBER’.

Any suggestions as to why? ROW_NUMBER is colored in a shade of pink automatically, which means from my knowledge “keyword” – so why does Sql Server think it should be a column and says the column doesn’t exist?

Thank you in advance.

Answer 1

The way you handle the query is wrong because

ROW_NUMBER Returns the sequential number of
a row within a partition of a result set,
starting at 1 for the first row in each partition.

You can try

Select 
from 
(
        Select row_number() over (partition by x order by x)SrNo,* from x
)A
where A.SrNo=1
