How is possible to get rows count of rowset in OLE DB? I have filled RowSet using CCommand and CAccessor and now I dont know how to get rows count.
I can go through all rows using MoveNext() but it does not seem efective.
Thanks

I have some data in sheet1,and sometimes the data starts in columns A4:C4, sometimes A8:C8, or sometimes another row. I'd like to get these data (only the first five rows of data) from sheet1 to columns A1:C5 in sheet2. So that every time the data is updated, only the first five rows of data will be retrieved from sheet1.
Can I a little help please, thanks in advance.
here is a sample sheet1 file.
I'd think this would work:
=ARRAY_CONSTRAIN(FILTER(Sheet1!A:C,Sheet1!A:A<>""),5,3)
A Query would also do the trick
=QUERY(Sheet1!A1:B,"select * Where A is not null limit 5",0)

I'm having an issue that I can't quite get my head around.
I have a very simple db for recording accounting transactions.
It contains, one table for the transactions, one query that returns the transaction amounts between two dates (with a total) and a report that shows the results of the query.
My issue is that I'm trying to add a total for ALL records into the report but I can't figure out how to do it without it just showing the totals from the query.
I've tried referencing the table directly but it returns a name error
I'd like to be able to do this without using VBA or SQL, any help would be most appreciated.
Thanks
I am reading from a google sheet of 100,000+ records but I want to load only the records after a certain date. ( so applying filter ) . But I haven't been able to accomplish that as I do not know how to access the column name without using foreach.
Here is what the data looks like from the googlesheet
So basically, I would like to filter the records something like this.
Timestamp ge '10/13/2021' so it will only return records for 10/13/2021 and 10/14/2021... etc.
Is this possible to do that? If not, what is the best recommended way to approach this issue as i just wanted to load daily records to sql db in the next step.
The Get rows action of the Google Sheets connector doesn't support filtering. You can only specify how many rows you want returned, and how many rows you want to skip. E.g. if you have 100,000 rows in your sheet, you can easily get the rows between 90,001 and 90,200, should you wish to do so.
While you can't use this connector to retrieve filtered data from Google Sheets, you can use the Filter array action to filter the retrieved data as you wish.
You might still need to use the For each loop to retrieve and filter data in chunks.
I have two sheets:
SheetA contains dates. It is the reference data.
SheetB contains dates and data on events that occurred on those dates. This sheet is updated regularly.
I am using IMPORTRANGE in SheetB to pull data from SheetA.
I sometimes need to insert rows into SheetB. For example, sometimes two events occur on the same date and I need a row for each.
However, when I insert a new row into the imported data in SheetB the new row is automatically filled with IMPORTRANGE data from SheetA.
I think there may be a solution with ADDRESS but I can't figure it out. Any help would be much appreciated!
As long as IMPORTRANGE returns a single array of multiple rows you are not going to be able to split those apart at all easily. Your best bet may be to convert the array into a standard range (Ctrl+C/Ctrl+Shift+V) and start the process all over if the source changes.
You might be able to combine two ranges (one from each sheet) in a QUERY that you sort by date.
In an SQLite table in my app, I need to have a column with row numbers going 1,2,3,4,5 (or to be able to get a row number for every row). Now I delete rows and add rows all the time, so I cant just put a number every time I add a new row, because when rows are deleted, the numbering will get messed up. So is there a way to get the row number, or create a special column that will act as row numbering? If so, how?
If you want this to be reset every time you add and delete rows, should this really be a column in your table?
For example, if you just want to be able to select the 20th row from the table, you can use the LIMIT and OFFSET clauses of SQL to select a particular row, e.g., to retrieve the 20th row from my news table, I could do:
SELECT * FROM news LIMIT 1 OFFSET 19;
Alternatively, if you really want a column with this row number information, you could just add a new INTEGER column type and then write an Objective C method to update the values for that column, and invoke that method any time you delete or insert rows in your result set.
There are a number of ways of solving your problem. You have to explain what you're trying to accomplish for us to help you out. The typical AUTOINCREMENT answer is what we generally use for table keys, but it sounds like you don't want this to be the key of your table, but rather something else.
If you use ROWID which is an auto-incrementing number, you can compute row numbers by selecting all of your data, ordered by ROWID and then using their index in the returned results as their row number. If you have some data model class you're creating, you could pass that in to its initializer.
If that won't do what you want, then how about adding some more details about what you're trying to do. Are you sure you need a row number?
You don't want to go changing all the existing records in your database when you delete rows that make "holes" in your row-umber scheme.
SQLite already supports what you want, with the ROWID. When you make a select query, just specify it to sort on ROWID, and all your returned records will be sorted in their proper order, and you can iterate over them in their order.

FWIW, there are certainly places where you should prefer direct SQLite over Core Data. However, those are rare cases. In general, reach for Core Data first, and fall back to SQLite only when CD does not serve your needs.
Just use an autoincrement primary key for the table. then there is always a unique identifier you can access a record.
