Good Day

I am trying to convert a nvarchar to bigint and getting this error msg:
Error converting data type nvarchar to bigint.

Below is the piece of code i've used:

select subnet,CAST(subnet as BIGINT)
from IP_Subnet_Table

The field (subnet) does not have null values

Please assist.

make sure you dont have any non numeric data in column

try this first and see if it works


select subnet,CAST(subnet as BIGINT)
from IP_Subnet_Table
WHERE ISNUMERIC(subnet)=1

A fast shot:
cast(replace(subnet,'.','') as BIGINT)

how do you think you can convert this to bigint? the closest you can get is


select subnet,CAST(replace(subnet,'.','') as BIGINT)
from IP_Subnet_Table
