Hello all
This is my first question.

Im pulling data out of an oracle database with asp.

Im trying to construct an email address on the fly from payroll data. Unfortunately the forename field also contains middle names, so i want to remove all text after the space (chr(32)).

Im using this code which does the job if the field contains a middlename (ie a space), but leaves the field blank if only the first name is entered.
I need it to return the fistname irrespective of whether it contains a middle name.

select substr(per_forename,1,(instr(per_forename,chr(32),1,1)-1))as email from mytable

"julian gregson" returns "julian"
"julian" returns ""

Hope you can help
Thanks in advance.

Julian

Hi JGregson,

> select substr(per_forename,1,(instr(per_forename,chr(32),1,1)-1))as email from mytable
How about

select substr(per_forename,1,(instr(per_forename + Chr(32),chr(32),1,1)-1))as email from mytable

As this always ensures that there is a space at the end so your statement will always return everything up to the first space.

Thanks
Had to slightly alter the code to:

select substr(per_forename,1,(instr(concat(per_forename,chr(32)),chr(32),1,1)-1)) as email

Many Thanks
Julian
