I apologize if this is redundant.
How would one fill an empty column with a sequence of numbers? The
column exists in a table with aproximately 1000000 rows of data. I
believe in oracle the following would work:
update foo set bar = rownum;
....but 'rownum' does not seem to exist in mssql. The numbers do not need
to be in order, but I would like to keep them somewhat small.
Any help would be appreciated.
Hello.
I don't know if its an sql question or an ssrs question.
I have a matrix that it column are months.
In the dataset I only have part of the manth (like: 1 , 2, 3, 5, 6, 7).
The problem is that it skip the 4th month and it doesn't look good.
Is there a way to add all month to the matrix column?
Thanks.
I'm trying to simply change a column definition from Null to Not Null. It'sa multi million row table. I've already checked to make sure there are nonulls for any rows and a default has been created for the column. My log isset to autogrow and as the alter column colname char(6) Not Null runs thelog begins to grow. If I use no check BOL say the optimizer won't considerthe change. How can I change the nullability of a column that currentlycontains no nulls without using up extreme amounts of log space?Danny
View 1 Replies View RelatedHi,
I currently have a column in a table with data type char and length 500. However, not every column fills up the entire 500 length, and I would like to fill up the rest of the spaces with dots. Is there a setting in SQL to do this? I do not want to use varchar since I want a fixed length with dots at the end. Any ideas?
Thanks,
Alan
Hi, I'm new to sql server but have used oracle sequence numbers to create unique keys in my tables. I've been looking for examples on how to create a sequence type table in sql server and have also found that there is a column called identifier but am unsure how to use this... I created a table and used this column attempting to insert (thinking it would autoincrement) but it fails... Any insight into how I can accomplish a sequence type activity for unquie numeric ids would be helpful, Thank you for your help,Jay

I am looking for ways to add new column to a table with records inside. If I add the column using this statement:ALTER TABLE Table1 ADD NewColumn1 decimal(18, 2) NULLThe column would appear at the end.
Is there a way to set where the column should be placed? (Excluding dropping all columns and add the columns in sequence again). I know this might not be very important, I am interested in knowing how Enterprise Manager done this, since you can move a column up and down to change their sequence eventhough there're records inside.
We have an application which has had a big design floor and is now causing an issue which needs to be rectified. It inserted data in batches of 2000 rows which should have always been in sequence. A column was used which recorded an ever increasing numerical value for each row that was inserted. So batch 1 would have a start value of 1 and an end value of 2001. Batch 2 would have a start value of 2002 and an end value of 4002 etc.
The problem is the application which inserted these records in order, missed some records. So in actual fact we have:
Batch 1 = seq 1 - 2001 (total 2000)
Batch 2 = seq 2002 - 3998 (total 1996, 4 missing)
batch 3 = seq 3999 - 5999 (total 2000)
Now the missing data has been found, it will be inserted at the end of the table, as we cannot insert it where its should be as the sequence value has been used by the next batch already. Lets say the table is 10,000 rows so far, so the seq for batch 2, for example, will be 2002-3998, then after the missing data is inserted, 10,001 - 10,005. The application uses these sequences to show the range of data so where it should be 2000 rows being returned, it would now show 8003 rows - all the other batches between the first and last sequences for the batch!
I need to change the sequence values across the whole table so they are in order. I can select the data in the correct sort order as there is another unique key on the table, but unsure how best to use this to change the sequence column to be in order for all rows. Adding an identity column would work and then remove and rename the seq column, but I obviously cannot add this based on another columns sort order. The identity column would use the clustered key which is in the incorrect order!!

I have a Column called SaleID in some tables in a Database.The SaleID column has the int datatype. I need a stored procedure that returns the next value in sequence for the SaleID column.
For Example,
If the last value inserted into the SaleID column was 1022 the stored procedure should return 1023
If the last value inserted into the SaleID column was 1023 the stored procedure should return 1024.
If the last value inserted into the SaleID column was 1024 the stored procedure should return 1025.
Also an exclusive lock should be maintained while the the stored procedure is running.

select * from SampleI have here sample data given. What I want to do is, I want to check the RefID which is not having proper order of sequence number. If you see the RefID 1000, 1001 they are having properly sequence order in SeqNo field. But it is not in RefID 1002. RefID 1002 does not have proper order. It is because user has deleted a row which was having seqno 2. So i want to get what are all the RefID's are not having properly sequenced. So that I would be able to know these are all the RefID's are affected by delete statement that was done by user.

View 2 Replies View RelatedCurrently 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?
Please Help

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?
Thanks in advance,

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.

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 ?
For example;
Order no. 1, Customer 3,
Product 3, Qty 2, UnitPrice $20.00, ExtendedPrice $40.00
Product 2, Qty 3, UnitPrice $10.00, ExtendedPrice $30.00
Product 4, Qty 2, UnitPrice $5.00, ExtendedPrice $10.00 ---here I can be adding as many as needed
Subtotal $80.00
Tax $5.00
Total $85.00
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
