If you leave your identifiers as they are (i.e. mixed case, unquoted) then use your existing mixed case names in Access, and lower case names in PostgreSQL, everything should be OK.

Wow.
Ok, since I started on this particular project using an Access database for the backend with the idea now of migrating to PostgreSQL, if I change my syntax as you suggest for mixed case, will the Access db choke on it? If I were to switch to SQL Server or Oracle, etc after changing the syntax, would they accept the quoted syntax?
Thanks.
Larry

Hi Larry,
 
Try:
 
SELECT * FROM "People" WHERE "NameType" = 2 ORDER BY "LastName","FirstName","MiddleName"
 
Mixed case names must be quoted in PostgreSQL. The other easy way around it is to create (or rename) all your objects with lower case names.
 
Regards, Dave.

Thank you Dave, we figured it out using dropdb.
 
Another question: what is the proper .Provider string or .ConnectionString to connect to a PostgreSQL db from VB6 using ADO?
Here is what I tried:
 
.ConnectionString = "driver={PostgreSQL};server=ABCDATA;uid=lreagor;pwd=test123;database=BodyBuilder"
My SQL string to open the recordset is:
 
"SELECT * FROM People WHERE NameType = 2 ORDER BY LastName,FirstName,MiddleName"
It seems I get an error once I try to connect and open a recordset:
 
"Error while executing the query; ERROR: relation 'People' does not exist." (error -2147467259)
 
Larry

The code that *should* work was written was left in. I suppose it should be commented out though. If you're interested, the reason you can't drop the database is because Microsoft ADO helpfully keeps the connection open for reuse should we need it (a technique called pooling).

I was able to drop an unwanted one earlier from pgAdmin (pgAdmin II) when I was just testing the Access migration plug in.  Why is there a drop command available for databases if I can't do it from pgAdmin?

I attempt to delete (drop) a database and get the following message.
 
 
I am the only user. What do I have to do to delete an unwanted database?

Unfortunately you can't using pgAdmin (see http://www.pgadmin.org/pgadmin2.php?ContentID=9). The best way is to close pgAdmin and use psql on the server.
 
Regards, Dave.
