the last years I solved tons of "problems" with plain SQL, but
I think this one will require some programming...
a stored procedure, a vb, I don't know ...
Here is the point:
I'm trying to build a simple OLAP-cube out of personal data.
I get table_person with number, name, birthdate, and so on.
I get table_costcenter with costcenternumber and description and
I get a table_person_costcenter with the following structure:
person-number, costcenter, FROM-Date (and some other data, e.g.
workinghours per week(this and headcount are the measures in the cube))
so...
Person 1 is on costcenter CC01 FROM-Date: 01.01.1998
person changed next year
1 CC02 FROM-Date: 01.01.1999
...
2 CC02 01.05.1999
2 CC03 01.01.2000
and so on....
I can think of loops reading the hole table (roundabout 2000 records),
than the one, two or more records with the person-number 1 and so on
and fill in the missing Dates (every first of a month) BETWEEN the
first FROM-Date to the next FROM-Date and so on till the last record with personnumber X which will lead to CURRENT DATE....
but I never programmed in MS SQL. :-(
So every code examples are heartly wellcome...
many thanks in advance
Michael
PS:
The result-table should look like this
person costcenter date
1 CC01 01.01.1998 january
1 CC01 01.02.1998 feb
1 CC01 01.03.1998 march
..
1 CC02 01.01.1999
1 CC02 01.02.1998
.. when no other connections "1" to costcenter ...
1 CC02 01.02.2004 (current month)
I am trying to write a Stored proc to retrieve only records from my table tat do not have a DateTime value ie DateTime is NULL and for some reason simply adding a DateRemoved = NULL does not work. Can anyone please help me with solution to this issue please??? Thanks in Advance
In the database I am querying, there is a field called "group". I can find out when "group" changes with a time field that was logged whenever group changes. I am trying to find what the value was changed into.
Code: SELECT Assignment_Log.DBID, Assignment_Log.Assigned_Group, Assignment_Log.Submit_Date FROM Assignment_Log
This will tell me:
The unique ID of the database The group it was assigned FROM The time the assignment took place
I need to find the assignment TO
so what I need to do for the last column is something along the lines of...
Find the next record after the current record by looking at the next Submit_Date and view the Assigned_Group.
If no "next record" can be found, leave the cell empty.
I need to write a sp to fill a date field, if another field in another table is true. need the date to reflect todays date(the date the field was marked true). I know this is an easy one but I am over thinking it. please help.
I currently have a stored procedure that selects sales entries from a table and inserts them into a temp table. To execute this procedure you must enter the store number and the dates required.
What I am looking to do is run this procedure daily for one store daily to load the previous days sales into the temp table.
If I wanted to search for Jobs as a particular status (e.g. 0130) and wanted to keep the jobs at this status until it has reached 0500, 0125, or 0900 in it's subsequent status log entry, how can I write the SQL for it to achieve it?
I have the following SQL which searches for the Jobs at 0130, but don't know how to develop it further to search on the requirement above.
------ SQL ------- SELECT job.job_number, (SELECT MAX(jsl.job_log_number) FROM job_status_log jsl WHERE job.job_number = jsl.job_number AND jsl.status_code = '0130') as Last_Early_Warning_Status_Entry
[code].....
In the job_status_log table above, there is a job_log_number field which increments by 1 when there is a new status log entry.

Currently we have tables (in sql 6,5), many of them do not have primary keys. While I was trying to re-index (re-org), many of them got an error: "fillfactor 204 is not a valid percentage; fillfactor must be between 1 and 100." (many tables' fillfactor exceed 100 or more...) How can I fix them so I can upgrade to sql 7 ? Thank you for your help.
I am really confused about this whole fill factor thing. The way I understand it, is if you have a table whose data remains pretty much static, you should use a higher fill factor. Suppose you had a database where you had at most 150 transactions a day that changed the data, should the fill factor be left at the default(0) or increased? How do you determine how much to increase it? Is there a rule of thumb that suggests if you have x number of changes against a table, you should have a fill factor between y and z percent?
Hi all, While creating indexes for a table, I specified a fill factor of 70%. I then inserted a few hundred rows into the table. Is it possible to check to what percent the pages are full after the rows have been inserted?
You have a db with 50,000 records and you want to add 100,000 more. What should the right fill factor be? Is there a way to "calculate" a fill factor if you don't want to use default? Any help is appreciated. Thank you.
I have a web online table that is inserted about 1500 record one day. Each night, a DST is running to pull all data to anther database. How to set fill factor on a one column index to get the best performance? Current fill factor is 80%.
Hi experts, I would like to ask regarding FILL FACTOR. I observed that our system's loading is a bit slow, and some of the modules take 1 to 2 minutes loading. Maintenance activity is regularly executed based on the scheduled sets. Then I tried to checked the tables indexes/keys turns out that the FILL FACTOR is set to ZERO(0). I would like to know if the FILL FACTOR set to zero will be a factor for the system to slow down..????
How do you fill out an order form; there is an Order(OrderID, CustomerID, Subtotal, Tax, Total), Orderdetail(OrderID, ProductID, Qty, UnitPrice, ExtendedPrice)
How do I get those tow together in the same form, which can be called order, or invoice it doesn't matter as long as I can get them in the same form numberd like order 1, then order 2, ect. is it by stored procedure, or by ado.net, or both ? or is there anywhere I can find information? like a book? or website ?
I have one complicated problem with SQL data files. Say that we have four data files:
F1=2000MB F2=1000MB F3=3000MB F4=1500MB
We want to add 3000 MB on these files, and in the same time we want to make the files proportional one with each other:
Will do:
F1 + 500=2500MB F2 + 1500=2500MB F4 + 1000=2500MB
With my logic, the final result we’ll be:
F1=2500 MB F2=2500 MB F3=3000MB F4=2500MB
There is an algorithm or a formula to calculate the right value to add to each F1, F2….Fn files having S1, S2….Sn sizes for a T total value to add? Thank you in advance.
P.S. The problem can be complicated when we deal with more than one filegroups and with disk space availability.
All,SQL Server uses a proportional fill method to add data to file groups wherea file group has multiple files. In general this is a good thing.Unfortunately, the method appears to get switched off when new file(s) isadded. Other than exporting the data out of the filegroup, recreating thefilegroup and putting the data back in, is there a way to respread theexisting data back out and switching the proportional fill method back on?Thanks,Danny

Hello guys! I am relavtively new to ASP.NET programming ang was just starting out on my first project. I am using ASP.NET2.0 technology by using Visual Web Developer 2005 Express Edition and of course with SQL 2005 Express Edition. I would like to develop a database for our IP addresses, so one field of my table in a SQL data is the field for IP addresses.I would like to write a program wherein after clicking the button, that field will be automatically filled up with IP addresses (e.g, from 192.168.0.0 to 192.168.0.255).How do I accomplish this kind of dynamic filling up of fields? Thanks a lot!

You have 50,000 records in a database file and you know you want to add another 100,000 records in the next several weeks. What fill factor would you use to maximize performance? A.0(default setting) B.30 C.70 D.100 which one is correct? And how to calculate fill factor?
I am a little confused about what fill factor to use in creating a clustered index on one of our major tables. This table has about 4.5 million rows and currently there are 14 indexes associated with it, but no clustered index. I want to create a clustered index (on datestamp )on this table, but cannot really grasp what fillfactor I should use. The main use of this table is in daterange reporting. No deletes are applied to this table(except archiving on an annual basis). It grows by about 5 000 rows daily. From what I have read in BOL, a high fillfactor(100) is only applicable for a read only table, and I feel that at the time of creating a clustered index on this table, it is readonly, cos the data will never need to be reorganised to insert a new row into it, only at end. BOL states that a low fillfactor could degrade database read performance, and where the vast majority of our processing(reporting) hits this table,that is a major concern. BUT BOL also says that a low Fillfactor is recommended where there are changes to the data. Space is obviously important, but access speed is overwhelmingly more important. Should I use a fillfactor of 70/80/90 etc. Any help would be appreciated
I have some non-clustered , non-unique indexes on a medium sized table (25,000 rows). The fill factore is showing 248% on these indexes. I have tried setting the fill factor to various values 100% or less. The re build index seems to work, however the est min/avg/max size of the index all show appx 160Kb, whilst the actual size is in excess of 50Mb !!
We run a weekly rebuild of all indexes overnight, without any fill params and following this the fill on these indexes goes back to 248% !
I have also dropped and re-created the index with a fill of 100%, and it has still reverted to 248% following the weekly rebuild.
I have also looked at the server config, and the fill factor there shows a running value of 171% !!, although the current config is set to 0.
The server is stopped every evening, so no way should the config have a value of 171, especially since the max allowed value is 100.
Any advice/assistance would be gratefully received.
I know what fill factor is ... and know that I should set it high when I have static data tables (where the data rarely changes) and low when I expect to have page splits ...
but does anyone know what affect on performance this setting has ? I don't quite get what Books Online says about it.
Can u plz tell me what is fill factor and what its role in defining the indexes. It is by default 0% and can be set upto 100%, but what it makes difference if i change the percentage? Where it is exactly impacts? If u know any links then plz forward me.
