Обсуждение: Defining a Connection String in Windows XP
I would like to learn how to set a connection string.
I am running pgsql 9.0 on an XP. I found a list of connection string
examples:
» dotConnect for PostgreSQL (former Core Labs PostgreSQLDirect)
(PgSqlConnection)
» Npgsql (NpgsqlConnection)
» PostgreSQL OLE DB Provider
» .NET Framework Data Provider for OLE DB (OleDbConnection)
» PostgreSQL ODBC Driver (psqlODBC)
» .NET Framework Data Provider for ODBC (OdbcConnection)
I am trying to connect with SQL Maestro. Since pgsql provides an ODBC
driver, it seemed appropriate to work with the PostgreSQL ODBC Driver.
The suggested connection string is:
Driver={PostgreSQL};Server=IP
address;Port=5432;Database=myDataBase;Uid=myUsername;Pwd=myPassword;
I do not know if I should leave the {PostgreSQL} as is or should it be
replaced with something.
For Server, the connection is on the same machine so I would think the
value should be ‘localhost’ (without quotes).
For Database, I don’t know if this should be the name of a database
inside of my pgsql server or something else.
When I run:
Driver={PostgreSQL};Server=localhost;Port=5432;Database=myDataBase;Uid=user101;Pwd=pw101;
I get a message window that says “[Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified”.
The driver is supposed to be inside of a pgsql DLL but I don’t know
how Windows is supposed to find it. How should I set up the
connection string?

Yes, that's right.

Yes, it's the specific database to which you want to connect.

What you're doing above is creating a DSN-less connection. I haven't
done it that way, but have had no problems when creating a DSN first. Go
to Administrative Tools -> Data sources (ODBC) and create a data source
for the database. You can then use a connection string something like this:
dsn=yourDsnName;uid=myUsername;pwd=myPassword;

Ray,
Thank you for responding. OK, that was my first trip into DSN setup
and I got lost:
The first step is to choose and existing MS driver for an Office app
or 'Add' one from this 'User DSN' tab. The other tabs are:
System dSN, File DSN, Drivers, Tracing, and Connection Pooling.
I did not see a pgsql listed in any - what is the next step (or two)?

Hi Ray,
If you don't see the PostgreSQL driver listed under "Drivers", then it
hasn't been installed properly. How did you install it? You usually need
to run the downloadable installer:
http://www.postgresql.org/ftp/odbc/versions/msi
Once the driver is installed, you create a DSN of the type of your
choice (system, user or file) by going to the appropriate tab and click
"Add".
Ray.

If, when you click Add, you don't see 'PostgreSQL ANSI' as one of the choices, you don't havethe ODBC driver installed. If you do, just fill in the boxes with the database name, password, etc. Susan C. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Just for reference, the bat file would not run because there was not an existing pgsql driver. The msi file worked right off. I used a System DSN and it worked. Now to figure out what to do with it. BTW, what are some of the considerations for choosing DSN types System, File, User? Thank you very much, ray
