VFP Access Data from Cursor Alias

Posted on 2012-09-11

I'm trying to figure out how to access data from a cursor alias.
Normally I do this:

Open in new window

and the data is at cursorname.fieldname

I am trying to do this:

lcCursor = "cCursor"

Open in new window

and ALLTRIM(cCursor.fieldname) doesn't work.

maybe it's cause I've been up for nearly 30 hours now that it's not working??

Changing from string literal to a variable containing the cursor name can't be the problem. Simply check lnResult and used(lcCursor) in the first place. If lnResult<0, check for errors. If lnResult=0 check your default setting for asynchronous execution of SQLEXEC.
If lnResult>0 and Used(lcCursor) is .f., do you really do a SELECT?  Inserts and Updates don't create a result set. Calling stored procs it depends on the return type.

ALLTRIM(cCursor.fieldname)  must work but
ALLTRIM(lcCursor.fieldname)  cannot work and you have to use
ALLTRIM(EVALUATE(lcCursor + ".fieldname"))

or better

SELECT (lcCUrsor)

Thanks for the help. I just stuck with doing things the way I have done before and works.
Less work for me too ;)
