select orderid, orderno,
(select companycode from company where companyid = orderid),
(select companyname from company where companyid = orderid),
(select vendorcode from vendor where vendorid = orderid),
(select vendorname from vendor where vendorid = orderid),
(select vendoraddress from vendor where vendorid = orderid),
(select vendorphone from vendor where vendorid = orderid)
from orders
))

is better than:

select orderid, orderno, companycode, companyname, vendorcode, vendorname, vendorphone
from orders
left outer join company on orders.companyid = orderform.companyid
left outer join vendor on orders.vendorid = vendor.vendorid

or that:

select orderid, orderno,
(select companycode from company where companyid = orderid),
(select companyname from company where companyid = orderid),
(select vendorcode from vendor where vendorid = orderid),
(select vendorname from vendor where vendorid = orderid),
(select vendoraddress from vendor where vendorid = orderid),
(select vendorphone from vendor where vendorid = orderid)
from orders
where
companyid in (select companyid from company where companycode like ‘%C’)
and
vendorid in (select vendorid from vendor where vendorcode like ‘%V’)

it’s better than:

select orderid, orderno, companycode, companyname, vendorcode, vendorname, vendoraddress, vendorphone
from orders, company, vendor
where
orders.companyid = company.companyid and companycode like ‘%C’
orders.vendorid = vendor.vendorid and vendorcode like ‘%V’

and here I made a simple example, the more complex the more disastrous the so called “new best practices” wants you to work.

Not to mention the difficulties in .NET of getting the database table name or column name from a column in a dataset (especially if you have aliases). Yes I know you can call GetSchemaInfo but it does not return for instance the real table if the original SQL script has Aliases (the last time I have checked).

So first they told us the story that the way to work with database is only using stored procedures, then they added LINQ, then they realized that people was still struggling and they added Entity Framework.

If you follow the evolution of the .NET framework you would have to rewrite your app every year (focusing on the flavour data-access method of the day (all flawed in real world cases) and less on what you need to do.

In Powerbuilder you just collect all tables you need for your data entry graphically and without effort with few clicks, select the table that needs to be updated and then write:

dw_1.AcceptText()
dw_1.Update()
commit using sqlca;

And that works on multiple databases (SQL Server, Sybase, Oracle etc).

3 lines, yes, I know it’s horrifying that it’s so easy to do database applications with Powerbuilder, but for us, it’s better to be productive than trendy.
I know people that stated: I can’t accept that the system writes the CRUD for ME! ADO.NET allows me to do it myself and this is the correct separation between presentation and logic
(and they end up 99.99% writing by hand the same statement PB would write automatically).
For one table it’s ok, but when you start something serious it becomes incredibly tedious.

I can recompile an application from version 5 of Powerbuilder to version 11.5 almost without changes (and not because there are no difference between the versions but because PB always improved something that works and does not require a different way of doing the same things every 6 months)

Visual inheritance in Powerbuilder is an absolutely brilliant work of productivity.
Visual Studio does not even come close.
Now I remember I have to check out PB 12 (it seems that PB supports visual inheritance for WFC that is generally not supported by the .NET framework ).

Sorry for my bad English, it’s not my first language

% emca -config dbcontrol db -DBCONTROL_HTTP_PORT 1158

Could u pls explain what exactly the meaning of ‘mutex’ ?

It works with 4.0 U1 for sure (Bob’s comments above are simply not true)!
Also, guys, keep in mind that you will need to update the oem.tgz according to you own hw.

BTW – It also works for 4.1 but I am getting another error that has nothing to do with the SATA drivers – “unable to find image to install image not being mounted correctly”.

I will settle for the 4.0 U1 for now…

Many thanks,

Ben.
