Truncate specific number of characters in SQL cells - sql

Question

I have Description column in a table
Description
---------------
AA Check
B1 Check
RD/AA Check
WD_FA Examine
FF Examine
AA Pass
B2 Check
Examine
The desired output
Description
---------------
Check
Examine
Pass
Basically a case statement where it truncates from the left side of the cell. NOTE that the list goes on with different names and conditions, and some cells do not need modification (like the last row), so something similar to a case statement but not returning NULL if I did not specify the condition
Thank you

Answer 1

This removes the data up to the 1st space
case when x like '% %'
then substring(x, charindex(' ', x) +1, 8000)
else x
end
'AA Examine Device' -> 'Examine Device'
And this extracts the last word:
case when x like '% %'
then right(x, charindex(' ', reverse(x)) -1)
else x
end
'AA Examine Device' -> 'Device'

Answer 2

Following the white space that you have, and using DISTINCT, this gets the last word following a white space or returns the word if it's the only word.
declare #Description table (Description varchar(64))
insert into #Description
values
('AA Check'),
('B1 Check'),
('RD/AA Check'),
('WD_FA Examine'),
('FF Examine'),
('AA Pass'),
('B2 Check'),
('Examine')
select distinct
right([Description],len([Description]) - charindex(' ',[Description]))
from #Description

Answer 3

You can do it like below :
select distinct substring(Description, charindex(' ', Description) + 1, len(Description))

Answer 4

The question is too broad, but you can use something like that
DECLARE #Product TABLE (
[Description] nvarchar(255),
Condition int
);
INSERT #Product ([Description], Condition)
select 'AA Check', 1 union all
select 'B1 Check', 2 union all
select 'RD/AA Check', 3 union all
select 'WD_FA Examine', 3 union all
select 'FF Examine', 4 union all
select 'AA Pass', 1 union all
select 'B2 Check', 5 union all
select 'Examine', 6
select
[Description],
case
when Condition = 1 then replace([Description],'AA ','')
when Condition = 2 then replace([Description],'B1 ','')
when Condition = 3 then ltrim(rtrim(right([Description],len([Description]) - 5)))
when Condition = 5 then replace([Description],'B2 ','')
when Condition = 6 then [Description]
else
''
end as 'NewDescription'
from #Product
I hope it helps 🙂

Answer 5

Perhaps something like this:
;WITH CTE (Column1) AS (
SELECT * FROM (
VALUES
(' AA Check '), (' B1 Check'), (' RD/AA Check '), (' WD_FA Examine '), (' FF Examine '),
(' AA Pass '), (' B2 Check '), (' Examine ')
) AS A (Column1)
)
SELECT
CASE WHEN CHARINDEX('Check', Column1) > 0 THEN SUBSTRING(Column1, CHARINDEX('Check', Column1), 5)
WHEN CHARINDEX('Examine', Column1) > 0 THEN SUBSTRING(Column1, CHARINDEX('Examine', Column1), 7)
WHEN CHARINDEX('Pass', Column1) > 0 THEN SUBSTRING(Column1, CHARINDEX('Pass', Column1), 4)
END AS Results
FROM CTE
It would be painful if you have a lot of variables though.

Answer 6

CREATE TABLE [A] ( [Description] VARCHAR(100));
INSERT [A]
VALUES
---------------
( 'AA Check' )
,( 'B1 Check' )
,( 'RD/AA Check' )
,( 'WD_FA Examine' )
,( 'FF Examine' )
,( 'AA Pass' )
,( 'B2 Check' )
,( 'Examine' )
,( 'Examine Device' );
SELECT DISTINCT
CASE
WHEN [Description] COLLATE Latin1_General_BIN LIKE '[A-Z][a-z]%' THEN
[Description]
WHEN [Description] COLLATE Latin1_General_BIN LIKE '[A-Z][A-Z0-9]%' THEN
SUBSTRING([Description], CHARINDEX(' ', [Description]) + 1, 8000)
END AS [Description]
FROM
[A];
DROP TABLE [A];
