Hi,

 

I am trying to setup the Powerbuilder application in my local laptop and it is working fine from citrix environment. I am using powerbuilder 2022 R3 version and trying to connect to SQL server. I have the SQL native client 2012 installed on the laptop. The Database is allowing successful login from SSMS tool for Dev environment. However when trying to run the application from powerbuilder it is throwing an error - 'Could not open a connection to SQL server [53]. 

The DB profile is working fine from Powerbuilder. Please resolve this issue at the earliest.

 

Thanks,

Sailaja.

Microsoft EOL'd SQL Server 2012 Native Client years ago. You should switch to the supported driver:

Microsoft OLE DB Driver 19 for SQL Server

https://learn.microsoft.com/en-us/sql/connect/oledb/download-oledb-driver-for-sql-server?view=sql-server-ver16

In PowerBuilder use the MSOLEDBSQL interface.

SQLCA.DBMS = "MSOLEDBSQL SQL Server"
SQLCA.LogPass = "*****"
SQLCA.ServerName = "*****"
SQLCA.LogId = "*****"
SQLCA.AutoCommit = False
SQLCA.DBParm = "Database='mydbname',Provider='MSOLEDBSQL19'"

Hi Sailaja;

  If the PB IDE connects OK then have a look at the DB Profile that your using and it's settings in the preview tab. Make sure that your App is using the same settings to connect. The debugger is your friend.  ;-)

Just before you connect to the database, put a break pint in the debugger. Then you can check all your database parameters are correct. Look at the values in sqlca or the transaction object that is connecting.

I suspect one is wrong, then you can track the source of that in your code and fix the problem.
