i use excel to save data from dictionary to rebuild a dynamic created table. When putting data to table, it automatically inserts the data from dictionary to excel file. The reason is to rebuild the table when reopen the program.
The problem is that i have to clear the excel sheet, so that in case of rebuilding the dynamic table i dont se some lines from old data.
Therefor i tried some stuff to clear the sheet, but it puts only None as the result to the dictionary. That creates errors when it rebuild the table. Is there a way to inlcude such a funciton in openpyxl as it is give in vba?

I want to copy and paste bulk of data, let's say 5-6 rows from the Excel sheet to the front end at once in the same format and then hit save and that data will be saved to the database using Laravel. I am not concerned about how do I save the data (I can do it) but I am concerned about how to bulk copy and paste multiple rows and columns to the front end.
How can I achieve this?
Let's consider this as Excel sheet table,

I want to copy all the rows and to paste them at my front end so that I can save the data. How can I achieve this kind of bulk copy-pasting? Any suggestions or reference or help will be appreciated.
I'm importing data from a text file using Bulk Insert in the script component in SSIS package.
Package Ran successfully and data imported into SQL
Now how do I validate the completeness of the data?
1. I can get the row count from source and destination and compare.
but my manager wants to know how we can verify all the data has come a cross as it is without any issues.
If we are comparing 2 tables then probably a joining them on all fields and see anything missing out.
I’m not sure how to compare a text file and a sql table.
One way I could is write code to ready the file line by line and query the database for that record and compare each and every field. We have millions of records so this is not going to be a simple task.
Any other way to validate all of the data ??
Any suggestions would be much appreciated
Thanks

Well you could take the same file and do a look-up to the SQL source and if any of the columns don't match move to a row count.
Here's a generic example of how you can do this.
I need to insert a field in the middle of current fields of a database table. I'm currently doing this in VB6 but may get the green light to do this in .net. Anyway I'm wondering since Access gives you the ability to "insert" fields in the table is there a way to do this in ADOX? If I had to I could step back and use DAO, but not sure how to do it there either.
If yor're wondering why I want to do this applications database has changed over time and I'm being asked to create Upgrade program for some of the installations with older versions.
Any help would be great.
This should not be necessary. Use the correct list of fields in your queries to retrieve them in the required order.
BUT, if you really need to do that, the only way i know is to create a new table with the fields in the required order, read the data from the old table into the new one, delete the old table and rename the new table as the old one.
I hear you: in Access the order of the fields is important.
If you need a comprehensive way to work with ADOX, your go to place is Allen Browne's website. I have used it to from my novice to pro in handling Access database changes. Here it is: www.AllenBrowne.com. Go to Access Tips then scroll down to ADOX Code.
That is also where I normally refer people with doubts about capabilities of Access as a database :)
In your case, you will juggle through creating a new table with the new field in the right position, copying data to the new table, applying properties to the fields, deleting original table, renaming the new table to the required (original) name.
That is the correct order. Do not apply field properties before copying the data. Some indexes and key properties may not be applied when the fields already have data.
Over time, I have automated this so I just run an application to do detect and implement the required changes for me. But that took A LOT of work-weeks.
I have a CR using multiple Oracle tables with complex links. I have to change the structure of 1 table (add a field actually) but the new structure is not reflected in the crystal report. I have tried refresh or update the location but the newly added field could not be seen. I know there is a not so clever way to "solve" the problem is to delete the table and add it back but by doing that, I will have to recreate the link, rearrange the reports, recreate the calculated fields.... basically rewrite the whole report... any advice to help me quickly update the structure of the my ORACLE table would be highly appreciate.
Thanks,
What you actually need to do is to Verify the database.
Well, found that out ...accidentally. I updated the database location and refreshed it but the new schema was not updated. I decided to run the report anyway... At the time of the report execution, CR realized there was a change in the table structure and updated it! So I think the solution to this is updating the location then execute the report, CR will update it automatically. Do not need to delete the table and added it back because doing so will delete all the links and fields the tables was referring to.
I've been using Core Data for about a week now, and really loving it, but one minor issue is that setting default values requires going through and setting up a temp interface to load the data, which I then do away with once I have the data seeded. Is there any way to edit values in a table, like how you can use phpMyAdmin to manipulate values in a MySQL database? Alternately, is there a way to write a function to import seed values from something like a Numbers spreadsheet if it doesn't detect the storedata XML file?
For your first question, you could edit the file directly but it's highly recommended you don't. How to edit it depends entirely on the store type you selected.
Regarding importing or setting up pre-generated data, of course: you can write code to manually insert entity instances into your Managed Object Context. There's a dedicated section on this very topic in the documentation. Further, if you have a lot of data to import, there's even a section on how to do this efficiently.

Xcode has a means of creating a quick and dirty interface for a data model. You just drag the data model file into a window in interface builder and it autogenerates an interface for you. This lets you view the data without having to have your entire app up and running.
