Hi,
Let me elaborate with example:-
I having an existing TableA with below sample column & data
Date Amount Category Name
2018-01-01 -100.00 Debit-Out Jonathan
2018-01-01 -400.00 Debit-Out Jonathan
2018-01-02 -150.00 Debit-Out Jonathan
2018-01-01 +100.00 Credit-In Jonathan
2018-01-02 +400.00 Credit-In Jonathan
2018-01-03 +150.00 Credit-In Jonathan

Now, i want move the data to another table, called TableB, with below features
1. To add [id] column below, [id] is auto increment during insert
2. To add [DebitOutFrom] column on last, this is to attach the relationship of debit-out & credit-in, meaning to say, in Credit-In row, i know which row to be Debit Out previously, and only the Credit-In row required to fill up the [DebitOutFrom] column.

My sample data want to achieve as below, i had highlight the value in bold &italic, as below

Id Date Amount Category Name DebitOutFrom
1 2018-01-01 -100.00 Debit-Out Jonathan NULL
2 2018-01-01 -400.00 Debit-Out Jonathan NULL
3 2018-01-02 -150.00 Debit-Out Jonathan NULL
4 2018-01-01 +100.00 Credit-In Jonathan 1
5 2018-01-02 +400.00 Credit-In Jonathan 2
6 2018-01-03 +150.00 Credit-In Jonathan 3

Above example,
The row:4, the value of DebitOutFrom is 1, meaning this Credit row, previously is it being Debit out in row:1
The row:5, the value of DebitOutFrom is 2, meaning this Credit row, previously is it being Debit out in row:2
The row:6, the value of DebitOutFrom is 3, meaning this Credit row, previously is it being Debit out in row:3

Any suggestion?
1. Can it be insert first, then perform separate update process the [DebitOutFrom]? OR
2. During insert, able to achieve that at once?

The row:6, the value of DebitOutFrom is 3, meaning this Credit row, previously is it being Debit out in row:3

The value of [DebitOutFrom] , is from [id] value of Debit-Out row.

Any suggestion?

I know this post is a bit old but...

There's nothing in Table A to absolutely guarantee the correct order of data... that also means there's not going to be anything in table B that you can build your numbering on. The closest you can come by name, category, date, and amount. If that's what you want, then we can come closer. However, I suspect that the Credit amount won't always exactly match the debit amounts.

What are you actually trying to do? Create a running balance or ???
