  • Calculate average gas prices by year in excel

    - by ghostryder111
    I have 3 columns, A=Date, B=Price, C=Grade in Excel. I want to calculate the average price of fuel for each year and an overall average of all years by grade.

  • Supporting Large Scale Team Development

    With a large-scale development of a database application, the task of supporting a large number of development and test databases, keeping them up to date with different builds can soon become ridiculously complex and costly. Grant Fritchey demonstrates a novel solution that can reduce the storage requirements enormously, and allow individual developers to work on thir own version, using a full set of data.

  • Advanced cell selection in Excel

    - by Supuhstar
    I am new to this flavor of StackExchange, so if this belongs elsewhere, please move it; I figured this would be the best place, though. I am making an Excel Worksheet that simply stores basic financial data in 5 columns (Check Number, Date of Transaction, Description, Profit from Transaction, and Balance After Transaction) and indefinite rows. Each worksheet represents one month, and each Workbook represents a year. As I make or receive a payment, I store it as a new row, which, inherently, makes the number of rows per month indefinite. Each transaction's Balance cell is the sum of the Balance cell of the row above it and the Profit cell of its row. I want each month to start off with a special row (first one after column headers) that displays a summary of the last month's transactions. For instance, the Balance After Transaction cell would display the last row's balance, and the Profit from Transaction cell would display the overall profits of the month) I know that if I knew every month had exactly 100 expenses, I could achieve this for March with the following formulas for profit and balance, respectively: =February!E2 - February!E102 =February!E102 However, I do NOT know how many rows will be in each month's table, and I'd like to automate this as much as possible (for instance, if I find a missed or duplicated expense in January, I don't want to have to update all the formulas that point to the ending January balance). How can I have Excel automatically use the last entered value in a column, in any given Excel spreadsheet, in a formula?

  • Excel 2010 - more than 1 calculation within an IF() statement

    - by Da Bajan
    I have a situation where I need to calculate shipping values based on the length of the supply chain. Easy, however I need to have instances where an increased amount is required based on specific date criteria. My example is as follows: Shipvalue = 100 Date1 = 1/1/2013 (Jan) - ship 50% more than usual Date2 = 2/1/2013 (Feb) - ship 25% more than usual Date3 = 3/1/2013 (Mar) - ship 25% more than usual Supply chain length is: June - October 100 days November - March 140 days April - June 100 days The issue I have is that as there is an increase in the number of days, my formula: IF( Date1-(Supply chain length + any extra days)=today's date, shipvalue+(shipvalue X 50%), IF( Date2-(Supply chain length + any extra days)=today's date, shipvalue+(shipvalue x 50%) IF( Date2-(Supply chain length + any extra days)=today's date, shipvalue+(shipvalue x 50%), IF( preceding cell<>0,shipvalue, 0) ) ) ) Now the problem with this is that if the length of the supply chain increases then the formula misses all but the 1st increase. So, I thought of adding a variable that would be incremented and checked every time you made an increased shipping amount. So, how do I do both the calculation for the increased shipping value, and set the variable in one part of the IF statement?

  • How to lookup a value in a table with multiple criteria

    - by php-b-grader
    I have a data sheet with multiple values in multiple columns. I have a qty and a current price which when multiplied out gives me the current revenue (CurRev). I want to use this lookup table to give me the new revenue (NewRev) from the new price but can't figure out how to do multiple ifs in a lookup. What I want is to build a new column that checks the "Product", "Tier" and "Location/State" and gives me the new price from the lookup table (above) and then multiply that by the qty. e.g. Data > Product, Tier, Location, Qty, CurRev, NewRev > Product1, Tier1, VIC, 2, $1000.00, $6000 (2 x $3000) > Product2, Tier3, NSW, 1, $100.00, $200 (1 x $200) > Product1, Tier3, SA, 5, $250.00, $750 (5 x $150) > Product3, Tier1, ACT, 5, $100.00, $500(5 x $100) > Product2, Tier3, QLD, 2, $150.00, $240 (2 x $240) Worst case, if I just get the new rate I can create another column

  • Excel VLOOKUP using results from a formula as the lookup value [on hold]

    - by Rick Deemer
    I have a cell that I must remove the first 2 characters "RO" for each value in a column on a sheet called RAW DATA and put into a cell on a sheet called ROSS DATA. Some of the values in that cell have 3 digits after the "RO", and some have 5 digits. To do that I used =REPLACE('RAW DATA'!A3,1,2,"") Then I need to use this new resultant string as the lookup value in a VLOOKUP. The VLOOKUP will be looking at a named range called DAP on a sheet called DAP, in column 5 for an exact match, and I need it to return that value to the cell. I have tried using INDIRECT in different ways to no avail, and I'm not sure that I fully understand its usage. So at this point I am Googling for a method to do this and at a standstill.

What is the correct way to write this contains condition? Is there also specific a grammar for the condition language? I've been unable to find anything.

  • Best Way to Handle Meta Information in a SQL Database

    - by danielhanly.com
    I've got a database where I want to store user information and user_meta information. The reason behind setting it up in this way was because the user_meta side may change over time and I would like to do this without disrupting the master user table. If possible, I would like some advice on how to best set up this meta data table. I can either set it as below: +----+---------+----------+--------------------+ | id | user_id | key | value | +----+---------+----------+--------------------+ | 1 | 1 | email | [email protected] | | 2 | 1 | name | user name | | 3 | 1 | address | test address | ... Or, I can set it as below: +----+---------+--------------------+--------------------+--------------+ | id | user_id | email | name | address | +----+---------+--------------------+--------------------+--------------+ | 1 | 1 | [email protected] | user name | test address | Obviously, the top verison is more flexible, but the bottom version is space saving and perhaps more efficient, returning all the data as a single record. Which is the best way to go about this? Or, am I going about this completely wrong and there's another way I've not thought of?

  • comparing two tables [closed]

    - by sza
    I have two identical table ie all the columns are identical and one of the datatype is Text, one is varchar(255) and the rest are int. Lets say the table name is 'AAAAA'. Table AAAAA was processed and backed up earlier this month. Both the tables were storing data and now the second table is only storing data. I need to find unmatching records from the second table (BBBBB) which is storing data right now and add those records to Table AAAAA. Your help will be highly appreciated. I tried to use 'EXCEPT' but it does not support text datatype.

  • Excel Macro To Lookup a User Entered String, and return data from the field next to it

    - by CJG
    On worksheet A, a user is prompted to enter a product number, such as BCI610. On worksheet B somewhere, that value exists. I want excel to lookup/find that value, and then return the data in the cell that is right next to it one column to the right, by copying that data, and pasting it somewhere in worksheet A. If I enter BCI610, it should return the value M332651, because that is the number in the cell immediately to the right of BCI610. I tried VLookup and HLookup, but to no avail... Any suggestions?

  • Reliable Storage Systems for SQL Server

    By validating the IO path before commissioning the production database system, and performing ongoing validation through page checksums and DBCC checks, you can hopefully avoid data corruption altogether, or at least nip it in the bud. If corruption occurs, then you have to take the right decisions fast to deal with it.

  • Show (copy) data at "X" time and stop update

    - by Anka
    I have two sheets. In the first sheet, cell F4, I have 00:00:00 (countdown). G9, G10 and G11 are cells that receive live data (decimal numbers). In the second sheet, I have three cells linked from sheet1, G9 ='Sheet1'!G9, G10 ='Sheet1'!G10, G11 ='Sheet1'!G11 (which update themselves when data is modified in the first sheet). Now I want to set in sheet 2, (assume) cells B9, B10 and B11 to show me (copy) the values from G9, G10 and G11 from sheet 1 when the countdown was 00:00:05 (5 seconds before Start) and not update again if the data changes in the cell it pulled the data from. Like G9 ='Sheet1'!G9 at 00:00:05 and stop here, do not update anything. OK? I can do a part, but the real problem is: I can not make it stop cells to update. Stand frozen, freeze, not move, calm .. however. I do not want to seem pretentious (but my knowledge in excel is limited), the most appropriate would be a formula, not macro or VBA, if possible. I want to post a picture but I can not because of my restrictions. Well, if this is not possible with a formula is just fine with (not really) VBA.

  • Excel 2013: VLookup for cells that share common characters within cell but are both surrounded by other non-matching text

    - by Kylie Z
    I am pulling information from 2 different databases. The databases use different naming protocol for the exact same item/specified placement however they always have certain components of the name in common. The length of these names can vary throughout each of the databases (see the pic below) so I don't think counting characters would help. I need a formula (probably a vlookup/match/index of some sort) to pair up the names from the 2nd database name with the 1st database name and then place it in the adjacent column(B2) on sheet1. Until this point I've had to match, copy, and paste the pairs manually from one sheet to the other and it takes FOREVER. Any help would be much appreciated!!! For example: Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A13: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS728X90_728X90_DFA Common Factors: "ROSMSNAUTOSMASSACHUSETTS" & "728X90" Therefore A2 and A13 need to pair up In some cases, Database 1 and 2 will have a common name aspect but sizing will be different. They need to have BOTH aspects in common in order to be paired so I would NOT want the below example to pair up. Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A12: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS300X250_300X250_DFA Common Factor: Only "ROSMSNAUTOSMASSACHUSETTS" matches. "728x90" is not equal to "300X250" - Sizing is different so they should not be paired.

  • How can I write an excel formula to do row based calculations; where certain conditions need to be met?

    - by BDY
    I am given: An excel sheet contains around 200 tasks (described in rows 2-201 in Column A). Each task can be elegible for a max of two projects (There are 4 projects in total, called "P1-P4" - drop down lists in Columns B and D); and this with a specific %-rate allocation (columns C & E - Column C refers to the Project Column B, and Column E refers to the Project in Column D). Column F shows the amount of work days spent on each task. Example in row 2: Task 1 (Column A); P1 (Column B) ; 80% (Column C) ; P3 (Column D) ; 20% (Column E) ; 3 (Column F) I need to know the sum of the working days spent on Project P3 respecting the %-rate for elegibility. I know how to calculate it for each Task (each Row) - e.g. for Task 1: =IF(B2="P3";C2*F2)+IF(D2="P3";E2*F2) However instead of repeating this for each task, I need a formula that adds them all together. Unfortunately the following formula shows me an error: =IF(B2:B201="P3";C2:C201*F2:F201)+IF(D2:D201="P3";E2:E201*F2:F201) Can anyone help please? Thank you!!

  • Best way to rename existing unique field names in database?

    - by Rajdeep Siddhapura
    I have a database table that contains id, filename, userId id is unique identifier filename should also be unique table may contain 10000 records When a user uploads a file it should be entered in database with given rules: If there is no record with same filename, it should be added as it is (Ex. foobar.pdf) If there is record with same filename, it should be added as uploadedName(2).ext (foobar(2).pdf) If there are n records with same base filename (foobar), it should be added as uploadedName(n+1).ext (foobar(20).pdf) Now if foobar(2).pdf is uploaded, it should be added as foobar(2)(2).pdf & so on This pattern needs to be followed because the file is already being uploaded at client side using ajax before sending the details to server and the file hosting service follows the above rules to name the files. My solution: maintain a file that contains all the names and the number of times it has occurred. if a filename that exists in file is entered, increase occurrence count and new name is generated, else add to it to file if the new name generated is in database, add it to file and generate new name
