Automatically Reducing Precision On Numerics
Mar 26, 2008
Hi all,
I'm running a transformation script that's taking decimal(18,10) data and trying to shoehorn it into a numeric(9,6). generally this works, as most of the data in the original table is not using anywhere near the precision it's capable of, but once in a while I run into one that does use it.
Is there any way to automagically reduce the precision so that i can cram the data into the destination table?

Hi - just found this site yesterday. Does anyone have experience converting a numeric(11,2) column to a 'mainframe' format with 'trailing sign overpunch'. Any old mainframe programmers will recognize this: there is no punctuation (- or + or , or .) and if the sign is negative, the last character is } for 0, J for 1, K for 2, etc.
I wrote the following command to convert the 'openrtl' column, but is there some other way?
oprtl =
CASE
WHEN openretl >= 0 THEN str((abs(openretl*100)),11,0)
WHEN openretl < 0 THEN substring(str((abs(openretl*100)),11,0),1,10) +
CASE
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '0'
THEN '}'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '1'
THEN 'J'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '2'
THEN 'K'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '3'
THEN 'L'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '4'
THEN 'M'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '5'
THEN 'N'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '6'
THEN 'O'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '7'
THEN 'P'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '8'
THEN 'Q'
WHEN substring(str((abs(openretl*100)),11,0),11,1) = '9'
THEN 'R'
END
END,

I tried searching forums for the last hour and could not find much.
Rather then doing...
REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(RE PLACE(ISNULL(PHONE, ''), ' ', ''), '(', ''), ')', ''), '-', ''), '.', ''), ':', ''), '+', '')
I was hoping there was an equally efficient alternative that utilizes PATINDEX('%[^0-9]%', PHONE)
to some capacity (i.e. uses regular expressions to strip all non-numeric characters from the phone field)
I am certain this has been addressed before, just not sure if the "REPLACE to the nth degree" is the only solution.
THANKS!

I'm trying, through the SQL 2005 Mgt Studio, to export a simple table in a delimited format. I'm selecting a double quote as the text qualifier. My expectations were that only text type fields would be exported with the double quotes an numerical fields would not have any quotes around them. SQL 2000 does this just fine, but 2005 is exporting all my text type and numeric fields with double quotes. Is this a change to SQL 2005 or am I doing something wrong.
Thanks for the help,
Tim

Hi guys, how are you?
Ive got a little question, i hope you can help me up
in sql server i have 3 tables
Code:
user
id_user - autoincremental int, primary key
username - varchar 30
car
id_car - autoincremental int, primary key
carName - varchar 30
user_car
id_user - int, foreign key
id_car - int, foreign key
what i want to do, is to
1.- insert a row in User,
2.- insert a row in Car
3.- using SCOPE_IDENTITY, to insert a new row in user_car that relates the ids of the last added car with the last added user.
But i need that to be done in one single transaction.
Once that is done, i have another question
how can i do the same but where i can add a variable number of different cars? in other words, i add 1 user and then add 5 cars, then create 5 rows in the user_car where i have the id of the last added user with the incremental id of the last 5 added cars
how can this be done in one single transaction, i cant make it in 3 transactions cuz it would cause me a lot of trouble. Any help?
my transaction should be something like this
Code:
insert into user(username) values('user1');
insert into car(carName) values('car1');
insert into user_car(???,???)
but im not sure how to do this in one single transaction

Hi,
If I understand it correctly, you only need an LDF file to restore to a point in time after the last full backup? If this is so, then Could the LDF file not be reduced in size on perfoming a full backup?
Most of the time it's not an issue as there is enough space on the HDD, but is it possible to reduce the ldf file size periodically (manually would be fine). Is changing the recovery mode from FULL to SIMPLE and then back to FULL an option?
If so, is anyone able to tell me how, exactly, I can do this? ... I've sifted through the documentaion to no avail ... :eek:
Many thanks
Rob

I am trying to reduce the size of my tempdb using the DBCC SHRINKFILE command and get the following error.
DBCC SHRINKFILE: Page 1:1164376 could not be moved because it is a work table page.
How can I get around this so I can shrink the db?

Hi!
I'm quite new to SQL Server. I need to set a float datatype to display something like 3.55. However, all values that are stored in the float column are truncated to 4 or some other single digit. How can this be prevented?

Hello everyone,
I am sure this is a newbie question as I am new to Microsoft SQL server but any help is greatly appreciated. I am populating a SQL database from an AS400. The decimal numbers from the AS400 are coming accross with extra decimals. (ie. 63.02 is coming accross as 63.0200001)
Is there a way to limit the number of decimals in a float or real field - or a SQL command I can put in a script to truncate each field to 2 decimal places after they are populated.
Thanks,
Randy

Hello,
I have been trying to develop an automatic way of programmatically accessing datasources and performing some predefined(-supported) processing on them.
The question I would like to ask you people has to do with numeric fields. What exactly is precision? Is it the maximum length in digits of a field, or is there more to it? What about a "field's scale", what is it and how does it affect a field's value handling?
Thank you very much,
Dave

I have a table with a 'quantity' column (decimal 9:3) and a 'price' column (9:3). I have a third column 'amount' with a formula of (price * quantity). The formula gives the correct answer, but the precision is automatically set to 5. Is there any way to set the precision of the result to 2?
Thanks.

Hi All
I am trying to pull data from Oracle to SQL Server but if I use Oledb Source than I get this error
Error at Data Flow Task [DTS.Pipeline]: The "output column "CUST_ID" (590)" has a precision that is not valid. The precision must be between 1 and 38.
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC0204018 (Microsoft.SqlServer.DTSPipelineWrap)
The only solution I found is use DataReader Source,
But if I use DataReader Source everything works fine , I mean I am able to see the records and convert it desired data type (using Data Convertion component).
My question is what component should I use as Destination, coz if I use OLEDB Desination I get a red cross on the components although I can map all the columns.....

Hi all,
I have started to look at the way our production DB has been defined and set up, with the view to improving performance.
The DB is now 11gb, and the original size was set up as 3000mb, the rest has been take in 10% additional extents.
Now, back in my DB2 DBA days, this was a bad thing to have any data spread across extents as they may not be contiguous. I am assuming that is the same with SQL Server. Can someone confirm/deny this?
If this is the case, how can I get the DB back into one primary partition?
Thanks in advance.
Mike

If I have a transaction log in a database of size 1GB ( space allocated is during creation of database) currently only 300 mb of its space is used i.e. nearly 700 mb is free. If I want to reduce physical file size of transaction log by 200 mb and release it for operating system then How can I do it???

I have a production database of a size of 70 GB. Half of the data was archived and deleted from the current database. What is the best way to
reduce the size of the database, as we cannot shrink an entire database to be smaller than its original size? Thanks a lot!

I created few jobs that would archive the production DB and delete the archived data...
but it looks like the DB size is not reducing!!! Some times it looks like the size has increased!!
I think this is because of the log file size has increaded by the DELETE operations....But what can I do for this???
Please Help!!

Having difficulty achieving an end-result in transforming the results of a rowset query into XML.
Here is simplified test code that displays my problem:
declare @TimesheetHdrs table (EmpID int,EntryYear smallint,EntryPeriod tinyint,AdminNotes varchar(max),UserNotes varchar(max))
declare @TimesheetDtls table (EmpID int,EntryYear smallint,EntryPeriod tinyint,ProjCode varchar(25),ActCode varchar(25),ExpendCode varchar(10),EntryDate date,EntryQty decimal(7,2))
declare @Projects table (ProjCode varchar(25),ProjName varchar(200))
[Code] ....
The result of the above code is the following:
Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">
[Code] ....
Notice how there is a tremendous amount of redundancy in the XML. I was hoping to come up with an XML result of the following, which transmits the same data, without the redundancies.
Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">
<expenditure expcode="1" expname="Regular Hours">
[Code] ....

I'm trying to insert all the rows from a table to a new table.
(insert A select * from AA)
The reads on Profiler shows ar really high value (10253548).
First I created a unique clustered index and the reads shows (3258445), then I created a non clustered index expecting to have lower reads. Instead the reads shows (10253548).
I read creating indexes helps reduce reads. But it's not happening.
Any ideas what is going on?

Hi all,
We currently have an e-commerce app written in .NET with SQL Server backend and built-in CMS that works just fine. We are now implementing a service to remove the need for the CMS by automating the synchronisation of the e-commerce database with a back-office database (non SQL Server). The problem we have run into is that during some of the larger updates to the website (i.e. new product information), the e-commerce system is experiencing timeouts. The synchronisation service uses transactions while performing updates and so I am assuming that the timeouts are being caused by the transactions locking tables and data.
What steps can I take to try to reduce these locks? The transactions are as short as possible so I do not think we can reduce the amount of processing each transaction deals with. I was looking at different isolation modes, Snapshot in particular, to reduce the locks, but would like some advice from someone who may have dealt with this type of situation before I start messing around here. (The synchronisation service uses the default ReadCommitted level, BTW)
Any advice you have to offer will be much appreciated.
Regards,
Stephen.

I have a database who is in full recovery mode. I have four maintenence plans setup: database backup, log backup, optimization and integrity checkup. The last two plans run weekly and the first two run daily. I found that the log size often increase to a dramatically size in a very short period, almost same size as the database file (4G). Further I found that the size seems increase a lot after the last two plan runs.
My question is that the optimization operation(reconstruct index page) will write any reocord to log file? Is this possible a reason?
Now the log file occupy too much disk space (90% of space can be free). What I should do? Shrink database weekly?
Thanks

Hi I am in the process of creating a new db in sql. In my users table I wish to set the UserIds as Integer datatype. It defualts on precision 4. Does this mean that when the column auto increments as its my primary key with a seed of one, my highest number allowed in the table would be row 9999. ???
Also if you where to store a phone number in your db, what column type would you give it. I have used varChar but its all numbers i want to store. Would this suffice.
Thanks
