hi,
How can I extract part of this string
declare @string varchar(1024)
set @string = 'Total # of bytes : 128270200832 (119.46GB)'
I only need the numbers after : and without the (119.46GB)
select Substring (@string, Charindex( ':', @string )+2 , Len(@string))

Hi,
Can you try:
declare @string varchar(1024)
set @string = 'Total # of bytes : 128270200832 (119.46GB)'
SELECT SUBSTRING(SUBSTRING(@string, CHARINDEX(':', @string) + 1, LEN(@string))
, 1
,CHARINDEX('(', SUBSTRING(@string, CHARINDEX(':', @string) + 1, LEN(@string)))-1);

Just for fun, this can be done with four functions
😎
USE TEEST;
GO
SET NOCOUNT ON;
DECLARE @string varchar(1024) = 'Total # of bytes : 128270200832 (119.46GB)';
;WITH NO_SPACE AS
(
SELECT STUFF(REPLACE(@string,' ',''),1,14,'') AS NSPSTR
)
SELECT
LEFT(NS.NSPSTR,CHARINDEX('(',NS.NSPSTR,1) - 1)
FROM NO_SPACE NS;

To allow for some variations in the format:
SELECT string, numbers
FROM ( VALUES
('Total # of bytes : 128270200832 (119.46GB)'),
('Total # of bytes : 128270200832(119.46GB)'),
('Total # of bytes : 128270200832 119.46GB'),
('Total # of bytes : 128270200832'),
('Total # of bytes : unavailable')
) AS strings(string)
CROSS APPLY (
SELECT CHARINDEX(':', string + ':') + 2 AS numbers_begin
) AS ca1
CROSS APPLY (
SELECT SUBSTRING(string, numbers_begin, PATINDEX('%[^0-9]%',
SUBSTRING(string, numbers_begin, 1024) + '/') - 1) as numbers
) AS ca2

I don't like to have too much dependency on the specifics of the way the data happens to look now, i.e., forcing the starting string to remain exactly the same and/or a specific char(s) to appear after the data.
Thus, my idea was to have more flexible support for variations in the format, not, for me personally, solely on reducing the number of functions used, although efficiency was also a consideration, of course.
