select sysdate from dual in oracle

you can simply assign it

eg. today’s adte := sysdate;

why can’t you do similar in sqlserver?

why not just mention getdate() as opposed to select getdate().

Yeah if you want a database that struggles with high user concurrent connectivity, handles locking of data in the most inefficient way possible, has poor tuning capability, isn’t very scalable (compared to Oracle), handles locks/latches etc horribly, locks data when there is no need, can’t perform anywhere near the capability of oracle, the list is almost endless….

I’ve worked for numerous large banks and NONE use sqlserver as their main database, there are many many reasons for this.

To its credit Sqlserver is very easy to use, that’s its attraction, but to say it is better than Oracle is at best uninformed and worst a total joke where you simply don’t know the facts and are exposing your ignorance.

Don’t write Oracle off simply because as I suspect you have never used it properly and don’t understand it.

SELECT dual.dummy
FROM (SELECT ‘X’ dummy ) dual

insert into actions_log(operatorsid, actiontext) select o.id, ‘actions etc’ from operators o where o.operatorcode = @opcode;

Quote: “…you can’t run this sql anywhere but oracle …”

And it’s the only place that you WOULD run it (and you’d also be an unqualified, untrained, clueless web developer with an art degree (in the biggest, most disorganised mish-mash of UNIX-centrix crep out there)).

UNIX and Oracle are like Apple – a dying breed, in the minority, massively over-priced, massively unsupported (attitude of: better to restrict functionality – than support it), full of fan-boys, full of ‘information squirrels’ (it took me 20 years to learn – why should I help you, noob?).

It say’s it all that Oracle deals with banks – banks being responsible for bringing countries to their knees through corruption.

Good one Microsoft – keep your 99% coverage – let Oracle deal with the scum. Keep your business-model, with all users of all levels happy to help all others (that’s why UNIX and Oracle and Apple are failing).

Show me ‘dual’ in the SQL standards.
If it ain’t there, then don’t use it in customer solutions – period (that’s called ‘best-practise’), and if you can’t use it as best-practise, then it isn’t very useful – is it?

You spouting about ‘dual’ suggests that your customers have ‘dual’ scattered about their solutions – I as your customer would be asking why have you given me a lead-weight as a solution?

I’m having to learn PL / SQL atm and the help out there is so disjointed and ‘non-standard’ – you may as well make up your own standards – as you go.
Oracle really is atrocious.

Faster with exponential maintenance cost is no competition against slower with predictable maintenance cost (it’s only banks that don’t need to care about cost – they simply invent a new thieving scam to cover it).

SE

Since it doesn’t look like anyone has responded to you, “select seq_XXXXX.nextval from dual” (presumably from Oracle) returns the NEXT SEQUENCE NUMBER (aka “next value”) from the SEQUENCE “seq_XXXXX”.

This handy feature of Oracle allows for UNIQUE ids to be returned to MUTLIPLE queries (executing “simultaneously” [or as close to simultaneously as the scheduler will allow]).

THIS is another “feature” that cannot be mapped to SQL Server (espeically NOT with creating a DUAL table with a single column).

declare @opcode varchar(6)

SET @opcode = ‘fred’

Insert into actions_log(OperatorsID, ActionText)
select O.ID, ‘Actions that might or might not have an operator associated’
from dual
left join operators O on operatorcode = @opcode

Pinal Dave is our hero!

Are you insane?

select ‘anything you want’ from dual;
return -> anything you want.

select function(param) from dual;
return -> what function returns.

select builtinFunctions from dual;
return -> what function returns.

you CANNOT achieve a functionality of the magical dual table by creating single column single record table.

you CANNOT compare sql s*it with Oracle (by the way its name is Oracle =)

you can create a “PRIMARY KEY” constraint on column which has duplicated records with sql, where is integrity?

you can’t run this sql anywhere but oracle

select f_giantCalculator(f_anotherFunctionThatOnlyReturnsAnId(complicatedTable.id), anotherFunctionProvideSomethingToGiantCalculator(complicatedTable.sillyColumn)) from complicatedTable
where complicatedTable.color = f_colorChooser(‘mycolor’);

aaah, I’m using mysql for web projects, it does’nt care if i using php or .net Single thing to do with sql server is uninstall it and don’t criticize about Oracle without knowledge you expert.

Do you know what Microsoft says to Communication or Bank IT’s?
“We cannot provide service for your demands, go to Oracle”

do we have equivalent for
SELECT 1
FROM DUAL
CONNECT BY LEVEL <=

in sql server.

in one of the app am supporting i found that a select statement is being used to retrieve value from dual table:
“select seq_XXXXX.nextval from dual” and as i saw the dual table has only 1 column i think its not able to proceed with the next value and here its failing. correct me if i am wrong… and suggest me what shall i do?

Thanks in Adv.
