return nil

In the function FW_OpenAdoConnection:
Please replace
SQLEXPRES with your Server name
FWH with the Database name you want
Secret with your password

Next release of FWH includes TRecSet class.
This will be fully compatible with ADO syntax and also TData/TDatabase syntax.
Existing applications will run without any change. Just replace
oRs := TOleAuto():New( "ADODB.RecordSet" )
with
oRs := TRecSet():New()
Advantages are :
a) We can use oRs:Fields( "HireDate" ):Value or oRs:HireDate
b) We need not check if record set is empty before using MoveFirst(), etc.
We can safely use MoveFirst() or GoTop() etc everywhere. Error checking is builtin
c) Field Access and Assign provide for padding/trimming/null values/ and other necessary conversions and error checking. Also takes care of differences between different databases.

Hi,

Is this code valid for MySQL?

Thanks

Thanks.

Hi Tim,

I just sent you PRG.

Sincerely,

Darrell,

Thank you for the updated function file. The conversion now works perfectly.

Mr. Rao,

If you would like someone to test your new tRecSet( ) functions, I would be happy to do so. I now have a successful conversion of all 108 data files to SQL, and my application is being built with FWH / Harbour / MS Visual Studio 2013. It will be a slow process in rebuilding this app, but that is not a problem.

Tim

Dear Mr. Rao,

I am willing to test as well. We are converting a very large application to MS SQL.

Sincerely,

Mr Hakan ONEMLI

FWH Ado functions work for Access, MS Sql, MySql, Oracle and SQLite3.

Mr Tim and Mr Ortiz

In the next version, we propose to include export function based on bulk inserts which are ten times faster than the present export function. To start with they will work for text only data for MySql and MSSql only. While you may test the present functions, you may wait for a few days and check the new functions for your production software.

It is also a good idea that these functions and TRecSet are beta tested before release. I shall inform you in a few days.

Mr. Rao,

I will only be using MS SQL at this time. I realize that different versions have variants in the commands.

The function to import the DBF files to an MSSQL database worked perfectly. I am looking forward to the additional functions.

Tim

Mr. Rao,

Any progress on test versions of this capability ?

Thanks.

Tim Stone

Hi Mr. Rao,

I trying to connect MySql. I have installed mysql-installer-community-5.6.19.0 with developer edition.

My code :


I could not connect to mysql.


Can you help me?

MySql information:


My ODBC window.

Version 5.3 support was not there.

Please open adofuncs.prg and modify the part of static saProviders array relating to MYSQL
Present line:

Please replace this line with the following:

Please compile adofuncs.prg with this modification and link with your application.

Hi Mr. Rao,

I have added and no change. It still does not connect.

I was installed 64 bit connector. instead I have installed 32 bit connector again.
It connects now.

But there is a cInitCat variable in the sample. what should it be?
