Here is the psudo code ..

1) Create your .dbf
2) Open your recordset ...

Code: Select all | Expand

oRs:MoveFirst()

Do While .not. oRs:Eof
      
     Select 1
     Append Blank

     a->Field1 := oRs:Fields("Field1"):Value

Rick,
Thanks for reply,

1) Create your .dbf

That is my problem ... i cant create .DBF becouse i dont know fields ...
becouse RecordSet is openet berore that and contains data from executed SQL
I want to export data from opened recordset to .dbf file
So i mean to read first the fields from recordset, (filedname, fieldtype, fieldlen, fielddec )
and after that to create .dbf and insert data in .dbf file

Any solution please ?

Best regards,

FWH already provides a ready made function for this.

FW_AdoExportToDBF( oRs, cDbf, lEditStruct )

BTW I use Informix and i am not ready now to test it.

Can i find the source of functions:
function FWAdoDelRecord( oRs ) --> lSuccess
function FWAdoFieldType( oRs, n ) --> cType (xbase type)
function FWAdoFieldDec( oRs, n ) --> nDecs (xbase)
function FWAdoFieldSize( oRs, n ) --> nSize (xbase)
function FWAdoLoadRecord( oRs ) --> aRecord
function FWAdoSaveRecord( oRS, aRecord, nRecNo ) --> nil
function FWAdoStruct( oRs ) --> aStruct
function FWAdoFieldStruct( oRs, n/cname/ofield) or (oField)
-> field strut info { cName, cDbtype, nDblen, nDbdec, nAdotype, lReadwrite }
function FW_AdoExportToDBF( oRs, cDbfName, [lEditStruct] ) --> lSuccess

Understand.

We might consider expanding the coverage to other SQL DBMSs depending on the users' requirements.

Best regards,

They are all functions in the later versions of FWH and the proper way to get the source code of these functions is by upgrading FWH.
FWH being a priced product, we can not share the source code of FWH libraries freely over the forum or otherwise.
But the above functions are not really difficult and one can write by himself.

Avista,

We can help you with FW_AdoExportToDBF() (I will check it with Rao and I may send you some code by email) but as Rao has clearly explained to you, if you want to use the result of our hard work, you should upgrade your FWH version, thanks for understanding it.

[Antonio Linares]

You can keep using FWH 13.04, upgrade to FWH 14.06, copy the required functions that you need and continue using 13.04.

I am sure that you also ask your customers to get paid by your work

[avista]

Thanks to all

So probably FW_AdoExportToDBF( oRs, cDbfName, [lEditStruct] ) will not help for informix database

But the above functions are not really difficult and one can write by himself.

If possible i need some help about that how to write function which detect filedname, fieldtype, fieldlen, fielddec from ado recordset and after that i will create .dbf aind insert data from ado recordset.

Antonio,
If you can please send me some start sample source code

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

That means "all" functions in adofuncs.prg work for these DBMSs. Just a clarification. Many functions work for *all* DBMSs.

For example, for creation of Table on DBMS, we need to know specific datatypes of the DBMS. Also if keywords are used as some field names we need to know how to quote such field names which conflict with keywords. This is different for different DBMSs.

Except create table and sql generation functions, all pure ADO functions work for all DBMSs.
In particular,
Fw_OpenAdoConnection( cConnString )
FW_OpenRecordSet(...)
And all function listed above in this post including FW_AdoExportToDBF(..) work for all DBMSs.
