My data looks like this:

rowid      NewDetailData
 1      0BATCH-NEXTGEN-NEXTGENEMR-20160829CPM-651
 2      1P0007.63579.0000-1609168541-899972053-1230-CN25

 15      53-250.00
 16      54-244.9

 18      56-278.02
 19      57-V85.24
 20      71174807291

A single RECORD consists of having the 1st Character of the DetailData field between 1-7.

For example RowID 2-6 are for a SINGLE RECORD, RowID 7-10 are for a SINGLE RECORD, etc...etc..

I need a SQL SELECT Script that will "assign" a unique RowID_2 to all of the ROWS (1-7) for each record. I need something like this:

rowid , RowID_2, NewDetailData
 2,1,1P0007.63579.0000-1609168541-899972053-1230-CN25
 3,1,2P201608232016082399348-1-0-1
 4,1,51-401.9
 5,1,52-719.45
 6,1,71609168541
 7,2,1P0007.63512.0000-1093765679-100458751-1230-CN25
 8,2,2P201608262016082699347-1-0-1
 9 ,2,51-787.01
 10,2,71093765679
 11,3,1P0014.236945.0000-1174807291-2254912701-1230-GW23
 12,3,2P201608252016082599341-1-0-1
 13,3,51-402.10
 14,3,52-272.2
 15,3,53-250.00
 16,3,54-244.9
 17,3,55-414.01
 18,3,56-278.02

I'm afraid your words don't seem to explain fully the second (new) column called  RowID_2

why id row_2 = 1 for these?
 2,1,1P0007.63579.0000-1609168541-899972053-1230-CN25
 3,1,2P201608232016082399348-1-0-1
 4,1,51-401.9
 5,1,52-719.45
 6,1,71609168541


why id row_2 = 2 for these?
 7,2,1P0007.63512.0000-1093765679-100458751-1230-CN25
 8,2,2P201608262016082699347-1-0-1
 9 ,2,51-787.01
 10,2,71093765679

why id row_2 = 3 for these?
 11,3,1P0014.236945.0000-1174807291-2254912701-1230-GW23
 12,3,2P201608252016082599341-1-0-1
 13,3,51-402.10
 14,3,52-272.2
 15,3,53-250.00
 16,3,54-244.9
 17,3,55-414.01
 18,3,56-278.02
 19,3,57-V85.24
 20,3,71174807291

and why does rowid start at 2 in the second list?

The assignment of RowID_2 the numbers 1,2,3 was purely done based on SEQUENCE. This RowID_2 will simply increment by one throughout the entire LIST of RECORDS. I'm attempting to GROUP all records together by using the RowID_2 and assigning it a unique ID field.

RowID starts with 2 because the first row of data, in the DetailData field started with a '0', not '1-7'. I don't need any rows returned that have a DetailData start character of '0', just ignore it. Incidentally, this is the FILE HEADER....and there is a file FOOTER...which I think starts with '9'.

So I don't need rows where DetailData starts with a '0' or a '9'...

Additionally,  I guess a BETTER name for the column "RowID_2" should be.... "RECORD_ID".

Since this column really identifies the RECORD which spans multiple ROWS of data... 1-7....

FYI,...once I can assign this RECORD_ID, then I'll use it to further build my code to concatenate rows 1-7 INTO A SINGLE ROW OF DATA..for each RECORD.... which is my ultimate goal....

This is the closest I can get right now (time limited)
data
declare @YourTable table
    ([rowid] int, [NewDetailData] varchar(50))
;
    
INSERT INTO @YourTable

wasn't able to get to your other question as it's deleted now, so I presume you found a way to produce a comma separated list.
