Need Help Approximating How Much Hard Drive Space I Need For My DB Table.
May 12, 2007In our SQL Server database we will have a table that will be populated with about 2000 recordsper day. That is 2000 records per day for 5 days per week. Currently the computer we are using has about 50 gigabytesof available hard drive space on it. We are concerned that maybe we will need a bigger hard drive,based solely on the number of records entered into this table per day. The problem is I don'tknow how to calculate how much hard drive space we need. I think I read that using varchar,sql server 2005 really optimizes a database. Here is a typical example of data in ourdatabase. I put dots on three lines between the first and last sample record to justillustrate that there are many records in between.
Basically we only need 8 months of data at a time in the table and then we can purgerecords older than 8 months.Can someone help me approximate how much hard drive space I might need for 8 months of data,given the following sample record in the database?
Sample: -->34.5 4.08 10.6 .0012
Sample Table in my DB just for illustration:
(PPsquare inch) (Diameter) (Weight gm) (coeffOfSatFriction)
34.5 4.08 10.6 .0012...21.7 3.54 6.22 .019
Formatting Numbers In A Mixed Column (numbers In Some Cells Strings In Other Cells) In Excel As Numbers
Feb 1, 2007I have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
Any suggestions?

Mar 11, 2008
I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
Thanks for any help
Generate List Of All Numbers (numbers Not In Use)
Feb 21, 2007I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:

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.

Row Numbers Etc.

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.
Expression.Like For Numbers?
Aug 26, 2007Hi,
Is it possible to search in columns with a number datatype (I'm using an MS SQL database with bigint columns) with the ICriterion Expression.Like?
Normally the Expression.Like is used for varchar columns. However, if there's a bigint column with the value 167829 I want to search for example on %678%.

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.

I want to create a number that is unique.
The number will have 8 digits.

i am not able to generate number in the way i said. I am relatively new to SQL. so any suggestions as how to go about solving the problem???. Are there any samples/codes available for this.
Any help would be highly appreciated.

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
SigFigRound(7.12345,1)=7.
Any solutions?

Subselect With Numbers
Feb 18, 2002I have the following table:
CREATE TABLE ITEMS ([ITEMID] int, [itRULE] varchar(1))
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (11, 3)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (12, 3)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (21, 2)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (22, 2)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (31, 1)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (32, 1)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (41, 0)
INSERT INTO ITEMS (ITEMID, itRULE) VALUES (42, 0)
-- Those works and gives me 11,12,21,22
SELECT ITEMID FROM ITEMS WHERE itRULE IN (2,3)
SELECT ITEMID FROM ITEMS WHERE itRULE IN ('2','3')
-- This doesn't works
declare @Rule varchar(10)
set @Rule='2,3'
SELECT ITEMID FROM ITEMS WHERE itRULE IN (@Rule)
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()

Deleting Odd And Even Numbers
Aug 8, 2002I have two identical databases. I need to delete the even customer numbers from the first database and the odd numbers from the other database. I know I can do this writing a delete statement for each table. However there are a total of 54 tables.
Does anyone know a faster way to write the script without writing 54 scripts?
I would appreciate your help.
As always you guys are the greatest.

Getting MAX From Char Numbers
Jul 28, 2001I have a table which will recieve and interface file to be loaded. All the fields are there except an account_id field which is a char(12), but the data is a number 000000000001, 000000000002, etc. These numbers are to be incremented by one. I understand how to write the process using a cursor to run through all the records and to increment them before loading. My question is the best way to get the max number in the existing table which is the char(12) , and icrement the number by one, but retain the leading zeroes I will need. Anyone had the pleasure of doing this providing input greatly appreciated.

Formatting Numbers
Jan 18, 2005I am using a MS Access ADP connected to SQL Server Data
In a view I have the following formula:
dbo.tblQuoteItem.Cost + dbo.tblQuoteItem.Markup * dbo.tblQuoteItem.Cost * .01
this calculates cost + markup
I cannot get it to format in Currency
Ex:
Cost is $1.75
Markup is 2.00 (2%)
Total shows - 1.785000
I want $1.78
Also - I am using this formula to calculate the Quoted price for the Qty Entered
dbo.tblQuoteItem.Qty * dbo.tblQuoteItem.Cost + dbo.tblQuoteItem.Markup * dbo.tblQuoteItem.Cost * .01
Using a Qty of 2 for above, I get 3.535000
I want $3.53
