SQL BCP exporting to ASCII

Posted on 2014-07-25

Hi

I am trying to export data from an SQL table using BCP using the script below:

select @sql = 'bcp "exec bloc700dummy.dbo.reptoolGetCustomers @Salesman = MS" queryout "C:\Reptool\CustomerMS.txt" -T -c -S'

The resultant datafile is then used as data for a dropdown within a VB.Net application. I have an issue where if a data column within the SQL table contains nothing, it is exported as what apperas to be 0X0 which I believe is HEX for a space. The problem I have is that when I try to concatenate fields of data together (address details), as soon as an empty field is encountered, any data after that field is lost!

Can anyone advise if there is a different switch combination I can use within BCP to stop this happening or can I code around this within my application?

Many thanks

Steve

Nope. 0x0 is NUL. This has an undefined meaning in the context of an ASCII file. It has not character representation. E.g. in many languages the byte 0x0 indicates the end of a string. Thus your "data loss".

Use COALESCE(yourColumn, '') to return non-null, but empty values.

Well, no. You need either to adjust the procedure or embed in a SQL script used for BCP.
