Hi all,
I have got a database in mysql and i need to use the gis and that was in
VFOXPRO.I need to display my data which is mysql on the map which database
is in VFoXPRO.Is there any way to have communication betweeen these two DBs.
Thanks and regards,
venu.
Hi Venu,
I would like to know the OS your using (for mysql server), BTW if
your using window. Try installing the myodbc and configure it so that
vfoxpro can communicate with it.

Changing various buffer sizes can improve performance significantly,

Also, make sure you are using not debugging version of the server.

Hi guys!
Ok, I'm closer to beat Rushmore (VFP optimizer) now!
After some reading about MySQL optimization techniques,
here is the summary of what I've done:
1. Add a compound index to the table
2. Use EXPLAIN to check out the query (with GROUP BY on multiple fields)
3. Create the summary table
And

It's just occured to me that you're basically copying and entire table from
one place to another. If I recall correctly, FoxPro cheats somewhat in this
situation - it just copies the concerned files!

Indexes? hmmm... I knew those were useful for something :)
In Visual FoxPro I don't use indexes for this table... so I didn't
considered them
necessary in MySQL (now I think I need to get to the basics of RDBMS).
This table I'm talking about is a CDR (call detail record), so
is Rushmore.
Which indexes do you have on the tables in the query?

Hector,
I migrated from Visual FoxPro too. VFP has different style to work with a
table. MySQL gives you some advantage which you don't have it in VFP. for
example, try to connect to the work server from home and run this query. it
will take 5 days to finish it, but still MySQL takes 3 min.s
Sorry, but what did dou mean with 'Are you still using VisualFoxPro...'?

has anyone got any experience of this ? Does it work ?
We're using MySQL as backend for our VFP6-Application. It's working with the

Hi, it works very well via MyODBC with either SQLCONNECT(), SQLEXEC() into local
cursors or Remote Views stored in a local VP database.
