split the accounid and dbids between braces into two columns - sql

Question

I have a query to split the accounid and dbids between braces separately.
example: [14801].[42]
acid scid
14801 42
but I'm not able to separate after comma ,
example :
[27784].[41],[27781].[41],[27779].[41]
need a query to split this data into rows

Answer 1

you need to create function to split values into rows
create function [dbo].[udf_splitstring] (#tokens varchar(max),
#delimiter varchar(5))
returns #split table (
token varchar(200) not null )
as
begin
declare #list xml
select #list = cast('<a>'
+ replace(#tokens, #delimiter, '</a><a>')
+ '</a>' as xml)
insert into #split
(token)
select ltrim(t.value('.', 'varchar(200)')) as data
from #list.nodes('/a') as x(t)
return
end
select * from into #a udf_splitstring ('[27784].[41],[27781].[41],[27779].[41]',',')
output
[27784].[41]
[27781].[41]
[27779].[41]
coming result store in one temp table
SELECT TOKEN,REPLACE(REPLACE(SUBSTRING(TOKEN,0,CHARINDEX('.',TOKEN)),'[',''),']','') AS first_id
,REPLACE(REPLACE(REVERSE(SUBSTRING(REVERSE(TOKEN),0,CHARINDEX('.',REVERSE(TOKEN)))),'[',''),']','') AS second_id
FROM #a
output
TOKEN first_id second_id
[27784].[41] 27784 41
[27781].[41] 27781 41
[27779].[41] 27779 41

Answer 2

Try this:
DECLARE #START_ID VARCHAR(100)='[27784].[41],[27781].[41],[27779].[41]'
DECLARE #ID VARCHAR(MAX)
DECLARE #COUNT INT
DECLARE #TEMP TABLE(C1 VARCHAR(MAX))
WHILE( CHARINDEX(',',#START_ID))>0
BEGIN
INSERT INTO #TEMP SELECT SUBSTRING(#START_ID,0,CHARINDEX(',',#START_ID))
SET #START_ID=(SELECT REPLACE(#START_ID,(SUBSTRING(#START_ID,0,CHARINDEX(',',#START_ID)+1)),''))
END
INSERT INTO #TEMP SELECT #START_ID
SELECT C1,REPLACE(REPLACE(SUBSTRING(C1,0,CHARINDEX('.',C1)),'[',''),']','') AS SOURCE_ACCOUT_ID
,REPLACE(REPLACE(REVERSE(SUBSTRING(REVERSE(C1),0,CHARINDEX('.',REVERSE(C1)))),'[',''),']','') AS SOURCE_DATABASE_ID
FROM #TEMP

Answer 3

select n.ids.value ('id[1]','int') as accountid
,n.ids.value ('id[2]','int') as dbid
from (select cast (replace('<r><e><id>'+replace(replace(replace(
ids,'[',''),']',''),',','</id></e><e><id>')+
'</id></e></r>','.','</id><id>') as xml) as x
from mytable
) t
cross apply x.nodes ('/r/e') n(ids)
+-----------+------+
| accountid | dbid |
+-----------+------+
| 27784 | 41 |
+-----------+------+
| 27781 | 41 |
+-----------+------+
| 27779 | 41 |
+-----------+------+
| 28021 | 30 |
+-----------+------+
| 28024 | 30 |
+-----------+------+
| 29007 | 56 |
+-----------+------+
DDL + DML for demo
create table mytable (ids varchar(1000))
insert into mytable values
('[27784].[41],[27781].[41],[27779].[41]')
, ('[28021].[30],[28024].[30]')
, ('[29007].[56]')
