I have a central db as publisher on SQL Server 2005, which has SUPERVISOR user having sysadmin rights.
And created another client db with subscriber user (not having sysadmin rights on the publisher SQL Server 2005), say U1, on SQL Express 2005 instance. As subscriber is the owner of db of subscriber db, so has sysadmin rights on the SQL Express 2005.
Done all the pre-requisite for merge replication.
When I try to replicate between the publisher db & subscriber db with subscriber user, it gives error
"The Publisher failed to allocate a new set of identity ranges for the subscription. This can occur when a publisher or a republishing Subscriber has run out of identity ranges to allocate to its own subscriber or when an identity column data type does not support an additional identity range allocation. If a republishing subscriber has run out of identity ranges, synchronize the republishing subscriber to obtain more identity ranges before restarting the synchronization. if a publisher runs out of identity....."
Although, if the subscriber user is created as sysadmin on the publisher i.e. SQL Server 2005 then the synchronization works perfectly and synchronizes the data.
I would like to know why SYSADMIN right is needed to be given to the subscriber user at the publisher i.e. SQL Server 2005 instance???

Hi i think this is critical probs...,
But i think some solution will be there..,
If u know plz clear to me...,
I have one table like...,
Id s1 s2 s3 s4 s5
1 100 200 0 0 0
2 400 0 100 0 150
3 500 150 <null> 50 0
...................
...................
Like this i have records in my table...,
Now my question is, i want to show my record...,
what are the fields have values those only...,
Suppose if i like to show my 2nd record...,
I want to show the records like...,
Id s1 s3 s5
2 400 100 150 only...,
Suppose if i like to show my 3rd record...,
The query want to display like...,
Id s1 s2 s4
3 500 150 50
Means what are the fields have 0 or null values those records dont want to display...,
Using stored procedure or query anything if its possible plz tell me...,
Advance Thanks,
Regards,
Magi

Hi M.
I tried it , But only found that you can replace Null value at the most
select IsNull(fldCol,1) from tblTest where fldcol2 ='abc'
hope someone comeup with the required stuff,May be Next version provide this facility.

Hey all,
Are Stored Procedures always preferable to PQ's, when possible? Reason I ask is that i've used PQ's extensively during the last 3 years (or so) of development, and I'm wondering if I should "progress" (given that all my work has been, and probably will remain, with SQL Server, I'm not too worried about having to port anything to Oracle or whatever).
Some sites mention security concerns, but I had thought that PQ's were pretty good anyway, and certainly avoid SQL Injection style attacks. Are there other considerations?
Cheers,
Martin.

I use stored procedures only in all of my code. They are cached on the sql server so they will perform quicker. It also allows you to limit the rights of your user to only execute the stored procedures. They don't need any rights to tables at all. So that is more secure. I would suggest moving toward only using stored procedure.

The compiled query plan for a stored procedure has a slightly higher weighting than that for a parameterized ad-hoc query, so it will tend to stay around in memory for a little longer.
In security terms, you can GRANT access to EXEC a stored procedure without having to grant access to the tables that the stored procedure accesses. This allows you to control the entry points to your database. This is a defence-in-depth measure in case you happen to accidentally allow a SQL injection or disclose the credentials used to connect to the database, or they're compromised. Best practice is to only permit each user and/or application the rights they actually need to get their job done.
Don't go overboard, though. Some people are seduced by the idea of building a single stored procedure to handle querying a table or view with optional parameters (e.g. looking for books by title or by author). This often looks something like:
CREATE PROCEDURE SelectBooks
(
@title varchar(50),
@author varchar(50)
)
SELECT *
FROM books
WHERE
(title = @title OR @title IS NULL) AND
(author = @author OR @author IS NULL) They've found a syntactically valid solution, but it makes harder work for the optimizer. Further, the query plan gets compiled the first time the procedure is used, using the parameters supplied. If you specify @title the first time round, leaving @author set to NULL, the optimizer might choose to seek through an index on title. If you then call it with @author rather than @title, it may still try to use that index and fall back on a table scan (i.e. reading every row in the table), even if there was an index on title that it could have used. In this case, I think parameterized queries are better.
[EDIT:]
I've just tried an equivalent query on SQL Server 2000 SP4, with no primary key on the table but with a separate single-column index on each of the columns in the query. The table has 240,000 rows. SQL Server elected to do an Index Scan (that is, reading the index from start to finish) on the title column, whether you specified title or author. If instead you run the parameterized query specifying only the columns you actually want to filter on, it correctly picks an Index Seek to the value you're after. I'm not yet sure about SQL Server 2005.
In fact if you specify EXEC ... WITH RECOMPILE it's using the opposite index from the value you specify! Flushing the data from the cache using DBCC DROPCLEANBUFFERS causes the query using the above stored procedure to take 46 seconds! The database is 160MB but my laptop, a Core 2 Duo T7200 [2GHz], has 2GB of RAM so if you don't run from cold, it's sub-second. The index scan is so fast, even from cold, that the Client Statistics view in Query Analyzer shows a time of 0.

Thanks for taking the time to investigate that Mike - I'll try a similar test in 2005 to measure the performance of SP's vs PQ's... I remember reading somewhere that 2005 can optomise and cache PQ's, so it'll be interesting to see.

This subject is hotly debated and is often the cause of religious wars! Well on the web anyway 
http://www.google.co.uk/search?hl=en&q=stored+procs+vs+dynamic+queries&meta=[^]
Personally I like Stored Procs, they appeal to my OO side with their encapsulation of data access sql code in the database. Another advantage is not having to update your application to change a query. But as others have said dynamic sql definatly has its place and shouldn't be completely dismissed.

That's why I thought I'd ask you guys - everytime I searched Google the whole debate turned into a semi-religious debacle!

Hi All,
Any can help me out by telling what is the alternative of " Convert(Varchar(10), Date, 101) As MY_DATE " this in MS Access. this function is actually used in query to get short date. How can i get this type of short date in MS ACCESS
|
|
|
|
|
If you open up a blank query and go to the functions under date/time there is a formatdatetime function. I believe 2 is the option for the short date.

hello
In webform i have 4 date picker.
which are 1. Create date (that is todays date)
2. expirydate (i.e display automatically i write code todays date + 28 days)
3. warning date (i.e also automatically display. expiredate + 2 days)
4.updateDate(which we will select)
all code is correct
but when program run that time runtime error ocurrs.
i.e
The conversion of a char data type to a datetime data type resulted
in an out-of-range datetime value. The statement has been terminated.
In table i am taking datetime datatype.
pls give me a quick solution for this problem.
my code is ----
DateTime intWarningDate = DateTime.Now.Date.AddDays(28);
dtpWarningDate.SelectedDate = intWarningDate.Date;
DateTime intExpiryDate =dtpWarningDate.SelectedDate;
DateTime date1 = intExpiryDate.AddDays(2);
dtpExpireDate.SelectedDate = date1.Date;

date format of date picket depends on regional settings of control panel.
use convert() function while inserting into table.

convert cannot be used with MS Access.

Hi,
can u help me the datatypes of the dates in the table. Probably, I think the datatype is datetime (dd/mm/yyyy or so on) whereas the date value being passed could be either dd/mmm/yyyy or any character is included in that date
Thanking you in Advance
