Extract multiple strings from a column - sql

Question

I have a description field where data is going to look like this:
ID Description Title
1234 serial numbers are *XC54566, AB2345fg, 12IUT456* blahblah
I want to extract everything inside the two asterisk and show them in a column with ',' being the delimiter that differentiates between the serial numbers. The output would then look like
ID Serial_Numbers
1234 XC54566
1234 AB2345fg
1234 12IUT456
Looking for a SQL Server query to extract this information using SELECT and some form of substring/left/right function thingy.
Hopefully a SQL select statement.

Answer 1

If sequence does not matter, how about a string_split() or two ?
Example
Select A.ID
,Serial_Numbers = trim(C.value)
From YourTable A
Cross Apply String_split([Description],'*') B
Cross Apply String_split(B.Value,',') C
Where B.Value like '%,%'
Results
ID Serial_Numbers
1234 XC54566
1234 AB2345fg
1234 12IUT456

Answer 2

at the first I Use XML For retrieve the 2nd element then in the second step, to separate with , from STRING_SPLIT.
yo can use this Query:
select ID,trim(Value)
from(
SELECT ID,CAST('<t>' + REPLACE(Description , '*','</t><t>') + '</t>' AS
XML).value('/t[2]','varchar(50)') as A
FROM T
) as B
CROSS APPLY STRING_SPLIT(A,',')
I used the following table and data for testing
CREATE TABLE [dbo].[T](
[ID] [int] NULL,
[Description] [nvarchar](max) NULL
)
INSERT [dbo].[T] ([ID], [Description])
VALUES (1234, N'serial numbers are *XC54566, AB2345fg, 12IUT456*')
INSERT [dbo].[T] ([ID], [Description])
VALUES (5678, N'serial numbers , are *XC54566, AB2345fg, 12IUT456*')
INSERT [dbo].[T] ([ID], [Description])
VALUES (9784, N'serial numbers are *XC54566*')

Answer 3

//select * from dbo.search('XC54566, AB2345fg, 12IUT456')
CREATE FUNCTION [dbo].[Split]
(
#RowData nvarchar(2000),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table
(
Id int identity(1,1),
Data nvarchar(100)
)
AS
BEGIN
Declare #Cnt int
Set #Cnt = 1
While (Charindex(#SplitOn,#RowData)>0)
Begin
Insert Into #RtnValue (data)
Select
Data = ltrim(rtrim(Substring(#RowData,1,Charindex(#SplitOn,#RowData)-1)))
Set #RowData = Substring(#RowData,Charindex(#SplitOn,#RowData)+1,len(#RowData))
Set #Cnt = #Cnt + 1
End
Insert Into #RtnValue (data)
Select Data = ltrim(rtrim(#RowData))
Return
END
