Hello

I have carefully followed Bruce Armstrong' tutorial for connecting PowerBuilder 2017 R2 to PostgreSQL, but I have a trial version of Powerbuilder 2019 R2 which I am trying to connect to a PostgreSQL 10 database. So far, I have not been successful.

Is there similarly definitive information for making the connection in Powerbuilder 2019? and if so where?

I have a successful ODBC DSN connection and an ODBC datasource in PB where I can see the tables, but I can't access the data in the tables.

Any advice would be appreciated.

Thanks in advance. :)

Hi James;

   If you can connect and see the tables, then the ODBC connection sounds OK. If you cannot access the datum, then it could be because your DB User ID does not have "Select" privileges. I would suggest checking this in your  DB Schema.

Hi All

And thank you.

I have resolved the problem by

  1. eliminating upper and lower case letters in table and column names, 
  2. reducing VARCHAR  lengths to 255
  3. ensuring that user has all priviledges in the db.

(1 & 2) give access to the data

(3) I think, is letting me edit it.

(1 & 2) may be a bug, and I think it is because PostgreSQL is case-sensitive about lables and the PowerBuilder system files convert labels to lower case.

NB: PostgreSQL comes with a number of free tools that make modification pretty easy, but you have to create a new connection in PowerBuilder for them to be recognized.

From the beginning, I started naming the table field names in lower case letters.

I do have few (varchar) columns with length more than 255, all working without issues so far.

We have been connecting to Postgresql since PB 2017 (R1) through PB 2017 (R3), successfully, using the following DSN less connection, without any issues.

@ RunTime

SQLCA.DBMS=ODBC
SQLCA.DBParm="ConnectString='Driver=PostgreSQL ODBC Driver(UNICODE);Database=<Database>;Server=<ServerName>;Port=5432;UID=<UserID>;PWD=<Password>;',DisableBind=1"
SQLCA.Lock="RC"
SQLCA.AutoCommit = False

* Substitute <Database>, <ServerName>, <UserID>, <Password> with correct values.

*****************

Inside the IDE < DB Profile - ODB ODBC >  Need a DSN to connect

// Profile BaseTwoWheeler
SQLCA.DBMS = "ODBC"
SQLCA.AutoCommit = False
SQLCA.DBParm = "ConnectString='DSN=<DSN>;UID=<userid>;PWD=<******>'"

********************

If you face any other difficulties, do explain with more details.

Olan,

I use IP address to connect PostgreSQL db.

Sample from my ini file



[Profile Test_db1]

DBServer=Postgres

DBMS=ODBC

ServerName=192.168.1.25

LogId=<userid>

LogPassword=<pass>

Database=test_db1

DBParm="ConnectString='Driver=PostgreSQL ODBC Driver(UNICODE);Database=test_db1;Server=192.168.1.25;Port=5432;UID=<userid>;PWD=<pass>;',DisableBind=1"

Driver=PostgreSQL ODBC Driver(UNICODE)

Port=5432

Lock="RC"



// Note : DBServer is to connect different database < Postgres / SQL Server >

1) Do you get the "Select Data Source" popup window when you connect in the IDE?



I don't remember anything like that pop out..
