Renaming

P: n/a

I'm updating a legacy app with table naming that makes baby jesus cry.
It's a bit of a spider web though... no telling when and where the
tables will be called by name. So I wrote this for renaming tables (I
guess it would work for queries also). It changes the table name,
changes the table name, queries that refer to it, form and report
control sources, combo and list box row sources etc.

Anyone inspired enough to figure out how to make it update modules and
macros? Not sure if it's possible...

P: n/a
These days, if you open Tools | Options, go to the General tab, and check
everything under Name Auto Correct, you have a good chance that many names
changes can be made and propagated through queries and form/report
recordsources. To my amazement, I just found that changing a field name in
a table or changing a table name is recorded, even if you use vb to make the
change.

References in code are still a problem.

I think that Speed Ferret (http://www.speedferret.com, $200) takes care of
the source code problem, plus gives you some pretty nifty other abilities.

If you don't go for built-in or Speed Ferret, and try to take it on
yourself, be very careful.

First question, when you say that you are changing "queries that refer to
it", do you mean that you are opening the querydef, parsing the SQL, and
replacing old table names with new table names? If not, then you're going
to be in for a shock the first time you try to run a query and find out that
your tables (as named in the queries) do not exist. Good luck restoring
your queries to operational status.

(I'll dispense with one thing first: I would't even bother with table
naming oddities myself on a wholesale basis. So someone used weird names.
So what? Put your own desription in the description field and get on with
life. But hey, that's me.)

If I were going to take on the renaming of all the tables without Speed
Ferret, I'd do it in phases. I'd make a list of the table names in another
table. I'd add a mark to indicate those whose names just have to change.
I'd add a column to contain the new name I intend to use.

I would do the next step with about 20 lines of code in vb, but it would
work doing it manually just as well.

For each table whose name just must change, I'd create a query that selects
from the old name and save the query as the new name. Each query is just
"Select t.* From oldtablename As t". That's it. Now I have all the lovely
new table names in place and haven't butchered anything in my application.

Next, I might use some vb to open forms or reports in design view and notice
if the recordsource is one of the old names. When I find one, I would
simply replace it with the new name.

Next, I would put together a query based on msysobjects and msysqueries so
that I could find all references in queries to any of the old table names.
I would probably not try to use VB to go through querydefs and automate
table name changes. Way to many variables in the parsing necessary.
However, driven by my query on msysobjects and msysqueries I could filter
for a single old table name and see all queries that use it. I would open
each in turn and replace references to the old table name with the new table
name. The query will still work because I have a query under the new name.

And so on and so on. YOu can even create a form with a listboxes to display
the list of all queries, and use code for instance in a double-click event
to open the query in design view, etc etc.

And as you pointed out, you have to search through modules to find explicit
code references to the old table names. While you're cleaning this up, why
don't you make a list of public constants set to the table names and replace
hard-coded referenes to name strings with references to the costants. Then
you don't have to deal with names everywhere on the next pass of something
like this.

Eventually, when you are pretty sure you have ferreted out all references to
the old table names, make a final backup copy (I assume you will back up
frequently doing stuff like this) and then start removing the queries and
renaming old tables to their new names.

Per Rick Wannall:
I think that Speed Ferret (http://www.speedferret.com, $200) takes care of
the source code problem, plus gives you some pretty nifty other abilities.


Also worth a look: FindAndReplace from Rick Fischer

http://www.rickworld.com/
I've used SpeedFerret, but I find Rick's utility faster and easier to use. It's
also costs less....

>These days, if you open Tools | Options, go to the General tab, and check

apart from turning the app into a scene from cocoon, name auto correct
only goes so far. would be ok if it didnt have any forms or reports or
code or macros.
First question, when you say that you are changing "queries that refer to

replacing old table names with new table names? If not, then you're going

"Select t.* From oldtablename As t". That's it. Now I have all the lovely
new table names in place and haven't butchered anything in my application. <snip>and then start removing the queries and renaming old tables to their new names.
doubling the number of queries (already at 600ish) with a cryptic
naming scheme only to remove them again is not really a runner, this
will only hide problems that will surface once the queries are removed
and greatly complicate things along the way.
Next, I might use some vb to open forms or reports in design view and notice
if the recordsource is one of the old names. When I find one, I would
simply replace it with the new name.
seriously, dude - READ THE CODE!!!! it takes care of all of that -
querydefs, forms, reports, recordsources, control sources...
msysobjects and msysqueries so <snip>even create a form with a listboxes to display the list of all queries, and use code for
instance in a double-click event to open the query in design view, etc etc.
....or i could select a query in the db window and click edit... (which
i dont even need to do because i've already looped through them all in
code and changed them)
make a list of public constants set to the table names and replace
hard-coded referenes to name strings with references to the costants.


you mean:
Public Const pStrTblMyTableName = "tblMyTableName"

so that i can change this to to:
Public Const pStrTblMyTableName = "tblNOTMyTableName"

....seriously, trying to clear things up here. Unify, homognise and
simplify.

ok, I appreciate your attempting to help here - you didnt have to
reply, so thanks for your time. But next time you feel moved to offer
your tupence, RTFP... I'll check out speed ferret thanks. That might
have what I need for code and macros. if not, there's always find and
replace - i was just trying to create a on click comprehensive solution
to table renaming.

Many, possibly most, people who help in the newsgroups just don't have the
time or energy to spend reading lengthy (or even not-so-lengthy) code posts
unless the poster has a specific error they are encountering that may show
up by "skimming" what's there.

Even so, we do our best to help, so please don't hold it against us if we
can't provide the level of support you'd like.

For good suggestions on effective use of newsgroups, take a look at the FAQ,
http://www.mvps.org/access.

Your code, it appears to me, is replicating what has been done in commercial
and shareware products that many use, and have suggested to you. There are
many "nooks and crannies" inside an Access database where information may
"hide," so be prepared for lots of testing. Third-party tools such as Speed
Ferret (http://www.moshannon.com) and Find and Replace
(http://www.rickworld.com) have the advantage of having been around, used by
lots of developers for many years, and have had the opportunity to fill in
the gaps that might have been there in their early versions.

Best of luck with your project.

awww, now i feel bad for being rude!! i should probably cut back on my
coffee intake.
Seriously, whenever i get good help either through reading old posts or
posting a question, I try to help out others by posting answers to
questions I can answer... so i'd hate you to think i'm an @ss who is
just out looking for free help and berating respondants for providing
silly answers.
many "nooks and crannies"


and you can double that for this project, which has all the continuity
of a plate of spagetti. Thinking I may just save myself the heartache
and [learn to_live with It]

I'll check out those links though, thanks all!

cheers!

That wasn't what I was thinking about you. It is easy to get "wound up" in
the problem at hand, though, and not realize what we are asking others to
do. And, as for "silly answers," that's just a feature of newsgroups... I
give some silly ones, myself, at times.

I've been tempted to do a "How'd they _do_ that" presentation for my user
group, showing some _examples_. But, given the very reasonable price of the
software that does the job well, I've not really been tempted to try to do
the same complete application!

Again, good luck with your project.
