best regards

Yes.
First, you need to install either ODBC connector or preferably OLEDB provider for PostgreSQL.

Then
oCn := FW_OpenAdoConnection( cConnectionString, .t. )

Please refer to the documentation of www.connectionstrings.com to determine the correct connection string to be used.

[kajot]

ask for an example , because none work

[kajot]

with MSSQL works well

Does anyone use Postgres ?

If you have installed Postgre server on your computer, build the samples pgre01.prg and testpgre.prg in the fwh\samples folder. Go to the folder \fwh\samples and build with either buildh.bat or buildx.bat

I have just installed Postgre server on my PC.
Both the samples pgre01.prg and testpgre.prg worked for me.

I have also installed Postgre Oledb provider and I am able to connect to the server using ADO, with this connection string.

Code: Select all

Provider=PostgreSQL OLE DB Provider;Data Source=myServerAddress;
location=myDataBase;User ID=myUsername;password=myPassword;
 

Still testing with ADO. We propose to make improvements, where necessary, to the ado functions in the FWH version under release now.

in pgre01.prg and testpgre.prg occurs

TPQServer():New( cHost, cDataBase, cUser, cPassword, , cSchema )

when I compliling , I got error
xLINK: error: Unresolved external symbol '_HB_FUN_TPQSERVER referenced from (t.obj)'.
xLINK: error: Unresolved external symbol '_HB_FUN_PQEXEC referenced from (t.obj)'.

[nageswaragunupudi]

please go to \fwh\samples folder.

If you are using xharbour, then buildx pgre01
If you are using harbour, then buildh pgre01.

You will not get any unresolved externals.

I am using xHarbour.com (simplex ) with Pelles ISO C compiler 3.0

and get error
xLINK: error: Unresolved external symbol '_HB_FUN_TPQSERVER referenced from (t.obj)'.

xLINK: error: Unresolved external symbol '_HB_FUN_PQEXEC referenced from (t.obj)'.

Both Harbour and xHarbour provide a library "pgsql.lib" for connecting to PostGre server.
So users of both free xHarbour and Harbour with bcc can straight away connect to PostGre server and start working with.

You need to link the pgsql.lib provided with your commerical xharbour.com
In addition, you need to create an implib for libpq.dll ( available in fwh\samples ) folder and link that too.

when I add pgsql from FWH s:\lib ( FWH there is in S:)

I get error

The lib provided by FWH is for Harbour and xHarbour with bcc only. It is not compatible with your xhabour.com
As I said before you need to get it from xhabour.com's libs or build it yourself with xharbour.com's compiler from the contrib sources.

[kajot]

when I am using lib from xHarbour.com (R: there is path to xHARBOUR.COM)

[R:\lib\sql.lib]
[R:\lib\libpq.lib]

I get error

xLINK: error: Unresolved external symbol '_HB_FUN_TPQSERVER referenced from (t.obj)'.

xLINK: error: Unresolved external symbol '_HB_FUN_PQEXEC referenced from (t.obj)'.

[nageswaragunupudi]

Please see my posts above.

You need to link "pgsql.lib".
If this is not available, you need to build it using xhabour.com's compiler from the contrib sources.
I hope the paid xharbour.com provides the sources.
If not, download the sources from free xharbour and build the library.
