Hi All,
What is the difference betwen real and float datatype of SQL server.
Please one exapmle for each.
The real datatype is like a float except that real can only store numbers.What does it mean: float can store even characters.
Thanks

I need to write a 'select' statement to fetch data from different tables, which are located on different servers.
Can any one help in writing this 'select' statement with out moving the tables on to same server.
Thanks in Advance.

I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT,
@BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125,
@BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original],
CAST(@SomeNumber AS BINARY(8)) AS [Binary],
dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted],
@SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float
(
@BinaryFloat BINARY(8)
)
RETURNS FLOAT
AS
BEGIN
DECLARE@Part TINYINT,
@PartValue TINYINT,
@Mask TINYINT,
@Mantissa FLOAT,
@Exponent SMALLINT,
@Bit TINYINT,
@Ln2 FLOAT,
@BigValue BIGINT
SELECT@Part = 1,
@Mantissa = 1,
@Bit = 1,
@Ln2 = LOG(2),
@BigValue = CAST(@BinaryFloat AS BIGINT),
@Exponent = (@BigValue & 0x7ff0000000000000) / EXP(52 * @Ln2)
WHILE @Part <= 8
BEGIN
SELECT@Part = @Part + 1,
@PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT),
@Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0
BEGIN
IF @PartValue & @Mask > 0
SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1,
@Mask = @Mask / 2
END
END
RETURNSIGN(@BigValue) * @Mantissa * POWER(CAST(2 AS FLOAT), @Exponent - 1023)
END
Thanks again Jeff!

i have 3 fields: start_inspect_datetime, end_inspect_datetime, Diag_Hrs.
so i want to get the difference of start and end datetime=Diag_Hrs.
here i am using the below stored proc.
but i am getting only the hours or minutes or seconds.
so how to get the hours(if diff>59 mins),minutes(if diff>59 sec),seconds.
for Ex: here diff=185 sec. then Diag_hrs should be 3 hours,0 mins, 5 secs.
so how we'll get this.
pl help me out asap.
Thanx
reddy
select Asset_Diag_Hrs= DATEDIFF(hh,start_inspect_datetime,end_inspect_dat etime) from asset_diag_trans_table

Can i restore a diff. backup alone without a complete backup?
(what i am trying is this.....there are two different servers at two diff. places....i need to have both servers in sync. at all times.modifications will take place in one server and the modifications have to be reflected in the other server.i could not go for replication as the servers cannot be connected.sending complete backups daily will be a overhead .hence planning to take complete backup once and send diff. backups alone on subsequent days to the other server.
how can i achieve this?)
Dear all
I am new to the MS SQL, my problem is as follows.
I am having a online database on sql 2k.
every 15 days we have to give payout from our system, so we
have a offline server in our office, we take the complete backup of that day & restore the same on the offline server,
& start the payout process.
The problem is that the full backup is a big file & take a lot of time for downloading from online server.
is it possible that we take on diff. backup of that day & will restore the same on the offline server so the file will take less time to download.
but my offline backup is 15 days old, will that update all the records or not?
regards
Abhijit
I have 2 databases:
1 from production and 1 from development.
None of the developers kept a changelog so i need to know what has changed (or what is different between the 2).
Any Ideas on how to do this?
In playing with differential backups, i have taken a full last night, 17GB, took my first diff today 16.5GB, took another diff right after, it was still 16.5GB, took another diff right after 16.5 GB. This database has 0 activity during the day, the import takes place @ night, and select's are done to it during the day. Any help would be greatly appreciated

Hello,
I wanted to know the difference between SQL Server 2005 ( RTM) Version and the regular SQL Server 2005 SP2. And does the RTM version have any service packs.
Thanks
Are there any tools/utilties that can diff 2 sql server databases. I know the DB Pro Edition of VSTS can do it, but its hard to justify a jump from my $800 copy of VS2005 Pro to a $5k-6k version of VS just to get database diff. The tablediff looks promising but I need it to do SPROCS and SFUNCS too. Any helps or recommendations would be appreciated.

Hi, I need to know the difference between Numeric and Decimal datatypes. In which we case we use numeric and in which case we use decimal? I searched in some sql related websites and came to know that both are same. Then what is the need of these two datatypes? Either Numeric or Decimal is alone enough? Please explain me in detail ....
Awaiting your replies...

I have a handful of jobs that I need to troubleshoot, but this one will hopefully give me enough insight to do the rest myself. I need to figure out why a Maintenance Plan that performs a Diff Backup on 4 databases, and then a transaction log back up on the 4 databases is failing. I just get the following error message, and I cannot tell what failed.

I need a to build a result as shown above in matrix, many countries will be in resultset and each country performance is evaluated based on previous year. (90-80)/80=12.50%. the problem is this year and segment values are calculated based on aggregate functions and is derived by means of specific formaule. for country1 in year 2006 for segment1 the value 80,90 is arrived by using sum(leadtime*Ordervalue)/sum(Ordervalue).
So i cannot store these current and previous year values for calculating the % bymeans of custom code, runningvalue cannot be used as the formulae already has an aggregate, is there any direct way to locate the cell references just like excel R1C1 with matrix? if so then i can refer the cells for calculating my %. please help.
Thanks in advance.

Is it possible to add a command into the query to output diff/compare scenario?
Thanks in advance for any help.
Friends,
I have taken backup of a database, of which Data (MDF) & Log (LDF) files are located on "E:...." directory.
Now, I am using the same backup file to restore on another PC which is having no partitions at all. I mean now I have to restore the database using same backup file, of which Data & Log files should be located on "C:...." directory only, as it has no partitions.
This restore process gives me error :
Restore failed for Server 'HSVMMICROFIT'.
Details : System.Data.SqlClient.SqlError: The operating system returned the error '5(Access is denied.)' while attempting 'RestoreContainer::ValidateTargetForCreation' on 'C:Program FilesMicroFitHealthStar v6.0 Server EditionDataMICROFIT_HealthStar_Data.mdf'.
What is to be done, in order to restore the database from the same back up file successfully, regardless whether the original physical location of the MDF & LDF file, is existing on current PC ??????????????
Please try to solve the same for me.... W8ing...
Hi @all,
I designed a query in report designer, data tab. This query runs 24 secs, when I execute it from the data tab in report designer.
Publishing the report and running it from the report server. The query needs 40x the time as in report designer.
Looking at the Execution Log, the report needs 800 secs for TimeDataRetrieval.
Why is it so much slower to run the query from report server? The report designer has also to retrieve the data, and runs so much faster.
Thanks for any hints

Hi ,
What is the diff between Logins & Users in SQL Server?
thanks

The DB Enginee is SQL2005 SP1. In MSSMS
the following query always finishes within 1 minute
SELECT *
FROM t1 INNER JOIN t2 ON t1.key= t2.key
where t1.StartTime >= '3/19/2008' AND t1.EndTime <= '3/20/2008'
AND t2.StartTime >= t1.StartTime AND t2.StartTime < t1.EndTime
however, the following always takes 10+ minutes
declare @pStartDate datetime
declare @pEndDate datetime
set @pStartDate='3/19/2008'
set @pEndDate='3/20/2008'
SELECT *
FROM t1 INNER JOIN t2 ON t1.key= t2.key
where t1.StartTime >= @pStartDate AND t1.EndTime <= @pEndDate
AND t2.StartTime >= t1.StartTime AND t2.StartTime < t1.EndTime
Both return same result. The only diff. is the blue part. Why the second one performances so badly?
Thanks.
We recieve about 4 million rows of data from a client per week. Each file is a complete snapshot of their data, we need to be able to find the rows that are different or new in the current weeks file compared to last weeks file.
Is this possible using 2 Flat file sources and some kind of sort/merge join?
If you are familiar with ORACLE or postgres its similar to a "MINUS" or "EXCEPT" respectively. Right now we load both files to separate tables and compare them in sql server which is very slow.
Diff. b/w Stored Procedures and Function??
When any of them is appropriate to use?
wots the diff b/w ncharand integer....??
