NewBee here. I am looking for a tutorial, article or sample code that details using first, last, next and previous buttons to display records from an SQLite database. Thanks in advance for your help, Jim
Look at the LIMIT and OFFSET clauses of SELECT:
http://www.sqlite.org/lang_select.html
All you need to do to build your pager device is to do a SELECT limiting to, say, 20 results, and supply an offset which is (page - 1) * 20. Your previous/next will decrement/increment your page number, and your first/last will set page to 1 or its maximum value respectively.

I would greatly appreciate some help with my current Facebook catalog ad predicament.
For a product with stock number 12345, our data feed brings it into the Facebook catalog as 616_12345 (the 616_ is consistent). This is the content_id.
To match the FB pixel content_id and track events, the stock number in the catalog needs to match the stock number on the site. So no events are being recorded.
I am managing the pixel and events through Google Tag Manager. I have set up a CSS selector that points to the stock number in an unordered list, but of course it just returns 12345.
Is there a way to create a variable in GTM that assumes a "616_" will be added before the stock number?
I've been told there is no way to remove that 616_ from the data feed - so this is the only option I can think of.
Thanks very much in advance!
Yes there is a way to create a variable in GTM - simple create "Constant" variable and set its' value to "616_". You can then reference this variable in your events and tags by simply using double curly brackets like so: {{VariableName}} . You can find detailed information here.
I had to import data in hcmposition table.
however, the positionid look like 000001 and I have used X++ to insert data into hcmpostion from an external table.
after the data is inserted, I tried to create a position form AX position form and I got the following error
Cannot create a record in Positions (HcmPosition). Position: 000001.The record already exists
in order to fix the issue I have tried to update the SYSTEMSEQUENCES table by updating the nexval field to be equal the maximum recid +1 available in hcmpositon.
however, I am still getting the same error.
You don't need to change nextval in the SYSTEMSEQUENCES table - it has a different purpose. Instead, try the following:
Open Human resources > Setup > Parameters > Human resources shared parameters > Number sequences.
Right-click the Position number sequence code, select View details.
Expand the General tab page, modify the Next number to be released from the number sequence.
Click the Status list button in the action pane to make sure it doesn't contain numbers that have already been used.
In AppMaker I have a calculated datasource and I've set its page size to 10.
In the function I call to return the records (queryRecords), the limit parameter is set to 11 (I don't change it on front side).
Why ?
That's a good catch. App Maker sets the limit to page size + 1 on all queries because it needs to look ahead to see if there are more pages or not (this allows us to fill in the "lastPage" property because we looked one ahead and found a record). But for calculated data sources this is pretty confusing, I'll file a bug to look into this. At the very least it needs some clear documentation.
I think if you did try to return 11 records, it should only show 10 on the client, and fill in the last page property appropriately.
I'm using a DataPager control, I want to change count items on each page.
For example :
the First page 6 rows, the second page 311, the third page 12, etc.
Is it possible? If so, how?
my advice is to do it manually, make your own sql query and customize the page size as you want
here are some tips that can help
to get range of rows that are needed for pagination user the row number
MS-sql row number
use the TOP to get the upper set of rows
select TOP 5 * from ....
for sure you'll need to get specific row numbers that will be displayed in the current page
select (--get row number--) from tbl_smth where row_num>5 and row_num<10
were as i guess that you have the page sizes in an array so you have to count them to determine the two numbers {5,10}
hope this will help
I don't know if its possible or not, but thought I'd ask. Many times reports need data grouping to have anchored to the bottom of the report some summary information, such as invoices. You don't want the totals shifting UPwards based on only 2 detail lines vs another with 20. I've tried working with using the Tablix bound to the data source for the output but couldn't get it quite right... It would either shift up, or force break and appear at top of following page.
So, if anyone has some ideas to help resolve that, that too would be great.
My second approach was to just use a simple report page footer. However, the overall "Report" page is not technically "BOUND" to any datasource. So, if I put a textbox in the footer and want it to show something, I can't pick "the most recent row from the datasource associated with the Tablix", it always requires an aggregate, such as
=First(Fields!SomeField.Value, "SomeDataSource" )
=Sum( ...
=Last( ...
etc...
I just want it to have whatever was the most recent... so I tried to use report variables to create one and was thinking to have it get updated per row being processed, so it always had whatever the "latest" value was and I could just dump that value at the bottom of the report.
Any suggestions to either would be great. Thanks.
I know this is an old question, but I had a very similar problem and came up with a unique solution. I had a statement that needed to have the payment slip print at the bottom of the page even if the statement line items wrapped over to another page. I solved it by:
Making all rows in the report a uniform height.
Calculating how many rows were required to fill the page (minus the height of my payment slip.
Getting the number of line items in the statement.
Calculating the remaining number of rows needed to push my payment slip to the bottom of the page.
Adding a sub-report with the calculated number of blank rows to pad out the necessary space between the line items and the payment slip.
The advantage of that approach was that I could generate bills for multiple customers, and since the padding is part of the group it would be customized for each customer's bill and bottom-justify the pay slip for each of them.
You can use a similar approach to push your "footer" info to the bottom of your page. Since it is still inside of your data group you'll have access to the data values you need as well.
In the footer you can refer to report item from report body, like this:
=ReportItems!myFooterValueTextBox.Value
The catch is that you can refer to only one report item in your footer, so you may need to add invisible footer row in your table and concatenate all your totals into one cell (myFooterValueTextBox) in that row:
=First(Fields!SomeField.Value, "SomeDataSource") + "|" +
Sum(...) + "|" + .... +
Last(...)
I used pipe as deliminator in my example, so then in the footer, I would split the string and place values in appropriate containers, like this:
=Split(ReportItems!myFooterValueTextBox.Value,"|")(0)
