I am trying to split fields in sql 2017. The column holds the following. I am pulling the first 50 characters and now I need to split those into 2 fields.
This is a test name1 3006 31
This is a test nameofsecondentry wls 37
Here is my Query to pull the data.
select matterinfosortname, SUBSTRING(matterinfosortname, 1, 50) from mattinf
where 1=1
and matterinfomatternum NOT LIKE '%.%'
and matterinfostatus = 0
This gives me the following:
This is a test name1 3006
This is a test nameofsecondentry wls
I need to split that data into 2 columns.
Any help would be greatly appreciated.

Assuming the parts to be split are: 1) the sentence on the left, and 2) the single string on the right. It appears after the initial 50 character split of the original string there are extra space characters on the end of the single string on the righthand side. To get rid of those spaces this query uses RTRIM. Then it uses REVERSE on the trimmed string and CHARINDEX to find the first (reversed) space

with data_cte as (
    select 'This is a test name1                          3006                  31' matterinfosortname
    union all
    select 'This is a test nameofsecondentry      wls                  37')
select *,
       len(substr.string) len_string,
       left(substr.string, len(substr.string)-space_char.ndx+1) first_string_val,
       right(substr.string, space_char.ndx-1) scond_string_val
from data_cte
     cross apply (values (rtrim(left(matterinfosortname, 50)))) substr(string)
     cross apply (values (charindex(' ', reverse(substr.string)))) space_char(ndx);

The data seemed inconsistent / "impossible" to me. How can the left-most 50 bytes be '3006' when that doesn't appear in the original value at all??

Pretty cool, @Steve.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
