A man goes to the doctor and says, "Doc, it hurts when I do this."  The doctor's response: "Don't do that."  What about not deleting the data within the transaction?

I think you're looking for something like this.  The first CROSS APPLY 'cma_check(cnt)' counts the number of commas.  The second CROSS APPLY 'wrd_check(cnt)' counts the number of words in the...

Yes I mostly agree with ratbak and I even narrowly agree with Joe.  If you've got access to pro software then use that 🙂  The code provided does sort of...

The query could split the input into left and right strings based on the location of the comma.  Then determine if the trailing character of the right string is a...

If the display order of the result set doesn't matter, using TOP(1) WITH TIES and ordering by the ROW_NUMBER

select top(1) with ties *

Regarding the specifics of trading scenarios it's just not my cup of tea.  If there was a specific SQL question (or answer) without any lingo then maybe.  But so to...

Thank you for your responses Rob.  It's an interesting story and your experiences with server code ring a bell which really resonates with me.  Ha, more could be said about...

So you think MONEY is a bad column for storing MONETARY values and that an INT which stores PENNIES (CENTS in US), is better. Is there a reason...

My apologies there was a mistake in the code.  You're correct there shouldn't be duplicates as you described.  In the 'xply_cte' CTE the 4th column contained an incorrect table alias. ...

It's not a good approach imo.  It's not necessary or polite to call anyone out.  For my part I'm not familiar with the terms and I'm generally uninterested in gambling. ...

You could maybe replace the whole WHILE LOOP'ing function with Eirikur's LEAD splitter.  If this is SQL Server 2016+ you could use the built-in STRING_SPLIT itvf (since the order...

The query could be simplified, no?  Maybe something like this

select top(1) p.AkcesAutoID

Here's another approach which uses a tally function to row multiply the 'Amount' column value(s) for both credits and debits.  A similar approach to FIFO calculation recently won some...
