How do I add Object-ID to Excel data so that I may use it in ArcMap 10?
Im going to assume youre using ArcMap for its relational database power rather than for spatial analysis. Or maybe youre prepping data for spatial analysis through a series of joins to avoid using Excel. When you import a dataset into ArcMap it will automatically generate a column called OID. It starts with then goes up. Ex 1 2 3 4. Open your file in Excel then Sort your data Ascending by the first column in your dataset Fill your new A column with a series 1 2 3 4 to the end of your dataset Open ArcMap then Import your Excel file Check OID and UID to make sure they match I hope this helps. Let me know if Ive missed something about your question. Feel free to private message me or send a screenshot.
Where can I get data that is stored in different sources, for example Excel, SQL server, Oracle, etc? I need to build a data warehouse for a university project.
You get data from your different sources thats why they are called sources. There are a few tricks You must get the data out of any proprietary format. So dont attempt to parse an XLS file extract it out to a CSV file (when saving the spreadsheet request that you save it in the CSV format). CSV is ama-separated-view format each field is and separated by ama. This is much more easily parsed by a database loading program like bcp or sql*loader. Use the data loading tools for the database mentioned to load the data into a tables designed to capture this data your staging tables. I am assuming that u do not have access to ETL (Extract Transform Load) tool otherwise you would use that to load staging tables. Finally you will need to design a few reports over your warehouse to show the new design. ordered-list Sounds like a fun project enjoy!!!
Using C programming, how do you extract information from specific rows of multiple excel files with the same exact format?
Basically C & Excel are not verypatible tools & you would have to do a lot of work to do this. Your best bet if you have to use these 2 exact tools is to first use Excel to convert all of the spreadsheets to CSV format (Comma Separated Values) personally I would set the separator to
What I want is to create a SQL database from customer data retrieved from Excel sheets and downloaded from multiple websites and then run some calculations on that data. Should I use Python and Excel or create a server to do those calculations?
As someone wrote recently depends on the calculations; some may be easier to do through Excel others through SQL Server. You can always use the Import-Export Wizard to go back-and-forth. You can create a database to export your Excel data into SQL Server run the operations there and then export back to Excel.
