New AdoRDD (free)

[Rick Lipkin]

This could be a complicated issue for Antonio and the ADO rdd developers .. RDD is so engrained with the concept of indexes .. for me ( with your help ) .. I have been able to leverage my rdd knowledge in substituting the ADO methods and have almost finished my complete re-write of a very complicated and robust application in MS SQL.

I see where the current ADO rdd builds on indexes for relations .. to me .. going into this ADO project .. I have totally abandoned indexes and sharpened my SQL to to just query what I want and not ( never, never ) do a SELECT * from TABLE unless I have to do an APPEND addnew() and that cursor is a bit UGLY 25k worth of records with a complete field recorset.

For the most part .. ( day to day ) data entry is limited to editing existing records and adding or editing related records spun off with a seperate recordset SELECT * ( or fields ) from <relational table> where <condition> = <primary key> .. returns only a cursor with limited records and I might add with no INDEXES... very fast.

I have noticed a 'severe' limitation to the SQL part of the ( open ) connection string in that if you list fields to limit your query .. if you add more than 6 or 7 .. xHarbours ADO will lock up .. apparently there is a limit on the length of the charactor string you can pass ..

I have taken a fresh approach to ADO and have totally wiped indexes off my radar scope. Now .. with that said .. I think the FIND method could be wrapped up into seek .. however if you use .dbf and ADO in combination you are going to have a translation problem .. what perhaps could happen is leave traditional seek in the ADO rdd for those developers that can use those databases that support indexes .. but spin off a new command like SeekAdo ( cSQL ) that one could use the oRs:Find() wrapper.

Also needed is the <order by> clause in the USE command which I have found to have very little overhead in presenting a records fetch.. plus I think it helps if the <order by> is your primary key ..

Lots of potential here .. could open up the whole RDMS world to xBase !!

I have installed a free MS SQL 2005 server on a server.

I've build a database with some tables.

How can I connect to it. Do I have to use a path or an ip adress.

Do I need a client dll ??

I think the examples in the adordd are working for a local file.

Thanks,

Willy Hermans.

Hi Willy,

try http://fivetechsoft.com/forums/viewtopic.php?t=7312

You can use Server Name if you use DNS Server or hosts file with names and ips.

No, you don't need a client.

Best regards,

Felix

Use "MediBank" Via "ADORDD" Table "Provider" FROM "Server\SQLEXPRESS" User "sa" PASSWORD "" SQL

If I run this I have an error code 16389 E_Fail:Open

The User is sa and there is no password

It works in visual studio

Any idea

Thanks,

Willy Hermans

Ehab,

You have to link usrrdd.lib too

Hello Antonio

is it possible create a table with MySql ?
I try this but doesn't work

DbCreate( "licenze;rag;MYSQL;localhost;root;mauri",;
{ { "FIRST", "C", 10, 0 },;
{ "LAST", "C", 10, 0 },;
{ "AGE", "N", 8, 0 } }, "ADORDD" )

Regards MAurizio

[Antonio Linares]

Maurizio,

In our tests we have not been able to create it, probably because we were using a remote MySQL host free website. If you are able to create it using standard ADO, then ADORDD should also work as ADORDD is just a wrapper on top of ADO and USRRDD

[gibaf]

O ADORDD funciona com Postgres ?
Se sim, como ?

Obrigado
