I have a databound dropdownlist that returns an integer (listID) I have a listbox that should return all the people on a membership list that aren't on the committee list with the ListID returned by the dropdownlist. The listbos code is:
<asp:ListBox ID="ListBox1" runat="server" DataSourceID="SqlDataSource2" DataTextField="ListID" DataValueField="ListID"></asp:ListBox>
SqlDataSource2 code is:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:mainshipsystemsConnectionString %>" >
</asp:SqlDataSource>
When the user clicks on the button for the dropdownlist to make their list selection I have the following in the code behind:
Protected Sub BtnSelect_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnSelect.Click
'make visible panel containing code to move members
Dim sListID As Integer = DDLGetList.Text
SqlDataSource2.SelectCommand = "SELECT MemberID, First, Last, Prefix, Suffix FROM Mainship.CE_Members WHERE (MemberID NOT IN (SELECT MemberID FROM Mainship.CE_Emails WHERE (ListID = 1)))"
End Sub
I get the following error:Description:
An unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the error and
where it originated in the code.
Exception Details:
System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not

I have listID = 1 in the above example for testing purposes.

So at the moment, I don't have a function by the name CONCATENATE. What I like to do is to list all those different values that go with a single CASE_ID to appear as a a comma separate list. You might have a better way of doing without even writing a function
I know I can do a JOIN(parameter, "some seperator") and it will build me a list/string of all the values in the multiselect parameter.
However, I want to do the same thing with all the occurances of a field in my result set (each row being an occurance).
For example say I have a form that is being printed which will pull in all the medications a patient is currently listed as having perscriptions for. I want to return all those values (say 8) and display them on a single line (or wrap onto additional lines as needed).
Something like: List of current perscriptions: Allegra, Allegra-D, Clariton, Nasalcort, Sudafed, Zantac
How can I accomplish this?
I was playing with the list box, but that only lets me repeat on a new line, I couldn't find any way to get it to repeate side by side (repeat left to right instead of top to bottom). I played with the orientation options, but that really just lets me adjust how multiple columns are displayed as best I can tell.
Could a custom function of some sort be written to take all the values and spit them out one by one into a comma seperated string?
Ok, I want to write a stored procedure / query that says the following: Code: If any of the items in list 'A' also appear in list 'B' --return false If none of the items in list 'A' appear in list 'B' --return true
In pseudo-SQL, I want to write a clause like this
Code:
IF (SELECT values FROM tableA) IN(SELECT values FROM tableB) Return False ELSE Return True
Unfortunately, it seems I can't do that unless my subquery before the 'IN' statement returns only one value. Needless to say, it returns a number of values.
I may have to achieve this with some kind of logical loop but I don't know how to do that.
I have a select list of fields that I need to select to get the results I need, however, I would like to insert only a chosen few of these fields into a table. I am getting the error, "The select list for the INSERT statement contains more items than the insert list. The number of SELECT values must match the number of INSERT columns." How can I do this?

I have a a table that holds a list of words, I am trying to add to the list, however I only want to add new words. But I wish to return from my proc the list of words with ID, whether it is new or old.
Here's a script. the creates the table,indexes, function and the storeproc. call the proc like procStoreAndUpdateTokenList 'word1,word2,word3'
My table is now 500000 rows and growing and I am inserting on average 300 words, some new some old.
performance is a not that great so I'm thinking that my code can be improved.

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.
I am trying to set up the relationship (Primary Key and Forign Key) in several tables. I would like to find a way also be able to set 'Fill Factor = 90%' in the script. Here is the code that i have so far:
