If you want to use substring the syntax is



SELECT SUBSTRING( MyCharField FROM 1 FOR 5) FROM MyTable



Is equivalent to VFP



SELECT LEFT(MyCharField,5) FROM TyTable





You only need to CAST if the selected field is not of character type.

Hi

Thanks for responding.

At 08:19 pm 13/09/2004, you wrote:

>for varchar fields you can use
>SUBSTRING(value FROM startpos [FOR length])

With your help I have tried this for a character field and it works

>SUBSTRING(CAST(value) as VARCHAR(100)) FROM startpos [FOR length])

Here I assume value means the field name? So I created something like

SUBSTRING(CAST(mAddress) as VARCHAR(100)) FROM 1 FOR 44)

this didn't work. Any other suggestions.




Regards
Bhavbhuti
