anyway to handle numbers larger than the float data type can handle?

Documenting Large Numbers Of SPs
Jul 27, 2007Hi All,
I have a large number of SPs that I would like to be able to document and provide this documentation to prospective clients. That is, provide them enough information without giving them the source code for the procedures.
I have found that all the parameters are in the sys.parameters table.
But I was wondering. Are the fields that are sent back out of an SP captured and recorded somewhere in the SQL Server catalog?
Is there an easy way to find out what fields are coming out of an SP?
Thanks in Advance

Dealing With Large Numbers Of Parameters
Sep 11, 2007Hi there,
I am getting a headache trying to research what to do when you have a large number of parameters to include in a query. For example, if I have a large number of checkboxes for the user to pick criteria for a report and they select several, I'm assuming it would be bad practise to say:
WHERE Field = "a" OR Field = "b" OR Field = "c" OR Field = "d" OR Field = "e" OR.....etc etc etc
Is there a good solution for this, given that the number of parameters may vary dramatically depending on what the user selects to include in a report?!
I'm running SQL Server 2000 with an ASP front end.
Any help would be greatly appreciated!
Thanks in advance!

How To Transfer Large Numbers Of Records Programmatically?
Nov 26, 2007Hello,
I have a VB.NET Windows Application with a SQL 2K5 back end.
The application creates a view which produces approximately 5 million records. I am attempting to transfer these records to a table programmatically, but every attempt causes a timeout. The name of the source server and view will change depending on the client's installation.
Using the standard SQL connection/command objects with the "INSERT INTO TABLE (SELECT * FROM VIEW)" doesn't work at all.
What is the best way to transfer these records programmatically?
Thanks,

SQL Server 2014 :: Index Dates To Numbers With A Large Data Set?
Jun 16, 2015I am trying to index dates to numbers with a large data set.
The first colums is index, the next is FactorsS, the next is value and the next is Date and the last is Lag.
Would it be difficult to write code that would determine the lag values. The lag value is based on the date value.
Index FactorS Value Date Lag
1 XYZ 2.3 12/31/2014 1
2 XYZ 1.4 12/30/2014 2
3 XYZ 3.3 12/29/2014 3

Viewing Large Numbers Of Stored Procs In SQL Server Management Studio
Jul 13, 2007I work with a large and complex reporting system with several hundred reports: the Programmability; Stored Procedures node of the object explorer has become very difficult to navigate.
Is there any metadata that can be embedded in the stored procs that would create subfolders like the existing System Stored Procedures node in this node of the object explorer?
I suspect that the correct answers are:
Rename all your queries with a rational naming convention;
Cull the deadwood;
Assign them to categories then export them to separate databases.
Unfortunately, one of these has already been done, and the other two will break several hundred dependent processes - the recoding and retesting is neither economical nor desirable.
Still, all advice is welcome. Pitch your answers at a banking geek who does intermediate to advanced stored procedures and triggers, but isn't allowed to play with sharp things (like sys objects) - but I can probably get help from a grown-up on the sysadmin team: I have discovered that the rumours about human sacrifice are baseless, and they will perform favours in return for beer.
This is also a good time to ask: just how many stored procs and functions are you allowed in SQL Server 2005?

Sql SORT Order Not Working On Numbers?
Jul 20, 2005Hello all... I'm using asp to get records from an access database, verysimilar to the way datagrid would work. The title of each column in my tableis a link that alternates the sort order between ascending and descending...my problem is that text WILL change its sort order just fine but nubers arenot always in order. ie: if sort order is ASC (ascending) I might see 2000,234, 789 (should be ordered but its not). I'm guessing that ASP is handingthe string as a text string (?) and getting confused, is there a way toforce ASP into treating the string as numerals if this is the case? anyother ideas? Thanks so much.here is one of my sql commands in case you want to see it. "sort" is avariable containing the recordset to sort by depending on which link isclicked. I hope I didn't confuse the whole issue because of a lack ofcaffiene over here :)strsql = "SELECT * FROM comments ORDER BY " & sort & " DESC"Thanks of the help, much appreciated.Eno

SQL 2005 Process Growing Very Large Working With Visual Basic 6
Sep 25, 2006We recently installed SQL server 2005 on a couple of our servers. I use Visual Basic 6.0 at the moment and use ADO to connect to our various SQL servers.
I recently discovered on one of the new servers, that every time my programs runs, (every 4 minutes for 12 hours a day) the SQL process shown in task manager grows by 1-10 Megs.
The SQL process was at 776,912K when I rebooted this afternoon. It started back up at 106,120K.
I am not doing anything differently than I did when my programs were talking to SQL 2000, and I have never seen this memory leak issue. Is there something extra I need to do in SQL 2005 to finish/clear these SQL queries and not bog down SQL's memory?
An example of how I would connect and do a SQL transaction:
Dim cn as ADODB.Connection
Dim rs as ADODB.RecordSet
Set cn = New ADODB.Connection
Set rs = New ADODB.Connection
cn.Open strConnect
select1 = "select firstName, lastName from clients"
rs.Open select1, cn, adOpenKeyset, adLockOptimistic
If rs.EOF = False Then
rs.AddNew
End If
rs!firstName = Trim(Text1(0))
rs!lastName = Trim(Text1(1))
rs.Update
rs.Close
cn.Close
At the end of the program's run I would:
Set cn = Nothing
Set rs = Nothing
DTSX Package Continues To Throw Errors When Working With Large Dataset.
Jun 7, 2006I have a dataset that is between 40-50K records that has to go through a process that is pre-defined. SSIS works just fine with the smaller sets even up to 20K but this job keeps blowing up saying something along the lines of cannot write to recordset destination. Does this make sense to anyone? The sever is a 2 processor with 2GB of ram. Physical memory usage spikes to about 1.6GB during the run but the processor never really gets above 30% usage. Does this product just not scale yet?

Dataflow To Excel - Convert Numbers Stored As Text To Numbers Excel Cell Error
Mar 27, 2007I'm trying to write data to excel from an ssis component to a excel destination.
Even thought I'm writing numerics, every cell gets this error with a green tag:
Convert numbers stored as text to numbers
Excel Cells were all pre-formated to accounting 2 decimal, and if i manually type the exact data Im sending it formats just fine.
I'm hearing this a common problem -
On another project I was able to find a workaround for the web based version of excel, by writing this to the top of the file:
<style>.text { mso-number-format:@; } </style>
is there anything I can pre-set in excel (cells are already formated) or write to my file so that numerics are seen as numerics and not text.
Maybe some setting in my write drivers - using sql servers excel destination.
So close.. Thanks for any help or information.
Some Things Not Working In 2005 And Working In 2000
Mar 3, 2006hi
I had a view in which I did something like this
isnull(fld,val) as 'alias'
when I assign a value to this in the client (vb 6.0) it works ok in sql2000 but fails in 2005.
When I change the query to fld as 'alias' then it works ok in sql 2005 .
why ?? I still have sql 2000 (8.0) compatability.
Also some queries which are pretty badly written run on sql 2000 but dont run at all in sql 2005 ???
any clues or answers ?? it is some configuration issue ?
Thanks in advance.
ExecuteNonQuery - Add Working/Update Not Working
Jan 7, 2004I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

Row Numbers Etc.
Sep 24, 2007
I have a sales report that includes dollar amount, tonnage, and profit margin among other things. They are currently sorted by tonnage sold from highest to lowest. I'd like to be able to place a number in a column counting 1 up for tonnage ranking. I'd also like to get a number ranking for sales amount ranking along with profit margin ranking. The most tonnage sold might not have been the biggest sale nor had the highest profit margin.
Does this sound like something that can be done within SSRS?
I should ad I'm runing MDX queries against a cube so I can't use T-SQL for ranking.

Calculating ID Numbers
Mar 28, 2008I needed to come up with an algorithm to create unique user- friendly account numbers such as AC0000000001, AC0000000002, etc...Where they increment by 1. I created a SQL function that retrieves the previous number generated, adds 1 to it, inserts the new value into the table, then returns the new value. I started thinking, what if the function is ran at the same time? What if function # 1 creates the new number, and function #2 creates a new number as well before function #1 inserts it? Is this a possible scenario? If so, how do I lock the process until the function completes to prevent this? Thanks for any help you provide.

Rounding Numbers
Jun 6, 2000Looking for a way to round numbers to a specified number of significant digits. The ROUND function rounds to a specific decimal place but does not take into account the level of significance of the remaining numbers. (i.e.
ROUND(7.12435,2)=7.12000) The type of function I need would round the number in the following manner: SigFigRound(7.12435,3)=7.12 or

I have two tables "customer" and "trades" i all ready have them linked and giving me all the individual items, oh and i have got it doing BETWEEN to dates, but i would really like to know how to show just the TOTAL trades for each cutomer on each line not every single trade for the customer.

SELECT ITEMID FROM ITEMS WHERE itRULE IN (2,3)
SELECT ITEMID FROM ITEMS WHERE itRULE IN ('2','3')
-- This doesn't works

Any idea?
I don't mind to change the data type if it works.
Random Numbers.
Jun 22, 2001I am trying to get random numbers to have a unique value for different processes, then I can identify each process. What happens is that I use rand() function without seed, so I got my random numbers, but after shutting down SQLServer and try to get again another random number after booting up, the same series of random numbers is given again and again. So if anyone knows how I can get unique values,even though reseting the server, and using random function or any other method which automatically provides unique values,I'll really appreciate it if you let me know it.
This is the function: select rand()
