You’re my master PinalDave. How do you think about HADR in denali??

For me, It’s like HA with cluster mixed with HA with Database Mirroring.

The correct table name is syslogins

SQL server stores the password in sysxlogins(master database).
Howver SQL Server creates the user’s password hash before storing it

but i want sp name because i want to execute the query with short cut. goto tools -> options -> keyboard -> place ths sp name on the corresponding short cut and click ok..

advantage of this short cut is u can write the table name and select it and hold u r shortcut key..

We had a postgres database once upon a time and it had the sequence ability. I always wondered why SQL never had it. With all that said, could we see sequence as an identity replacement in certain databases? It offers a unique id for a row not only across the table itself but across all tables. That may provide for some benefits on the application side.

Good to know that SEQUENCE has been introduced in Denali, i think this concept existed in oracle before. The SEQUENCE can be used for key generation type scenarios.

Hi Srikanth,

Varchar data type can be defined in two ways:
1) VARCHAR(n) where max value of “n” can be 8000
2) VARCHAR(max) where “max” indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes.

For ex:
– Created temporary table #test in temp database
create table #test (test varchar(max))

–Inserted 8010 character in column test
insert into #test values (REPLICATE(‘a’,8010))

– Stores more than 8000 char
select * from #test

Drop table #test

Regards,
Animesh

Hi, I am a newbie with SQL 2008, I can’t figure out how to sort a varchar column that has numbers and alpha mixed. I need the alpha to be listed first which contains CO1, CO2, A, B, C, then 1,2,3,
I tried “order by” and the numbers are showing as 1, 10, 100 and the alpha is listed last. Thank you for any help with this!

It could be used for generating Alpha-numeric primary keys .
