Re: Inserting a record into the middle of a subfile--suggestions?

Michael,

Arrays are not limited to 9999 records.

Perhaps you are referring to the limit of the size of a subfile? But,
then, this wouldn't be a reason to store the data in a file in QTEMP...
it'd merely be a reason to write a page-at-a-time subfile (which could be
loaded from an array just as well as a file.)

My understanding is that this thread was about inserting a record into the
middle of a subfile. To me, that's a very different question than "how do
I have more than 9999 rows in a subfile".

Load your subfile into an array in your program, then clear the subfile,

and reload it from the array, inserting the new row(s) where needed.

This is very easy, and runs very fast. I can't see any good reason to
use a file (in QTEMP or otherwise) that would only hurt performance.
Unless, of course, you need to do that because you need it saved to
disk...

I need to insert records into the middle of a subfile. The user can

enter
a keyword that's attached to a long description and I need to get that
description into the body of the subfile.

I could add records to the end and then resequence when writing to the
database but that won't be satisfactory from a user experience
perspective--the user needs to see the full text in order as part of the
entry process. My subfile record length (including hidden fields) is
about
400 bytes and I should have less that 50 records most of the time. I
have
four 132-character subfile records on the screen and already have used
the
fold/unfold option.

Copying the subfile to a variable-size array, inserting the records
where
needed, and then reloading the subfile is an option.

Another option is to have A/B subfile control/detail set up records copy
from the "A" subfile (+ inserts) into the "B" subfile and then display
the
"B" control record. SQL temporary tables and memory-resident tables are
possibilities also.

Where's a linked list when we really need it?

I'll be grateful for any suggestions and wish you all a Happy New Year.

thx...
