Hi,
Stuck with a problem and need help in resolving it. I have a column with the following information in it. I need to split the column and parse the values. Need healp in doing that. Never came situation like this before . I have Parsed one single values from but, not multiple times.
<TV<MR1#4.0#true#2.0#USD>VT>,<TV<MR2#3.0#true#1.5#USD>VT>,<TV<MR3#0.0#true#0.0#USD>VT>,<TV<MR4#0.375#true#0.19#USD>VT>
MR1 -Model Code,
4.0 - Percentage,
true - isAbs,
2.0 - AppliedValue --> This is Actual amount applied as tax.
USD - Currency
For the example provide , the totalTaxValue would be 2.0 + 1.5+0.0+0.19 = 3.69
Thanks in Advance!

I hope that this is part of a data cleansing process because it's complicated and won't be great for performance.

Here's a possible solution. Be sure to understand it. It uses DelimitedSplit8k function which is explained in here: http://www.sqlservercentral.com/articles/Tally+Table/72993/

Ask any questions that you have about it.

DECLARE @Sample Table(

string varchar(8000)

)

INSERT @Sample

VALUES('<TV<MR1#4.0#true#2.0#USD>VT>,<TV<MR2#3.0#true#1.5#USD>VT>,<TV<MR3#0.0#true#0.0#USD>VT>,<TV<MR4#0.375#true#0.19#USD>VT>')

SELECT SUBSTRING( d.Item, 5, 3),

REPLACE( PARSENAME(t.dotted, 4), CHAR(7), '.'),

REPLACE( PARSENAME(t.dotted, 3), CHAR(7), '.'),

REPLACE( PARSENAME(t.dotted, 2), CHAR(7), '.'),

REPLACE( PARSENAME(t.dotted, 1), CHAR(7), '.')

FROM @Sample s

CROSS APPLY DelimitedSplit8K( s.string, ',') d

CROSS APPLY (SELECT REPLACE( REPLACE( REPLACE( STUFF( Item, 1, CHARINDEX('#', d.Item), ''), '>VT>', ''), '.', CHAR(7)), '#', '.')) t(dotted)

I received and error -" Invalid object name 'DelimitedSplit8K' " when executing the query. I am using SQL Server 2012.

You're missing the DelimitedSplit8K function, which is here[/url]. If you read all the way to the bottom, the code is in one of the downloads at the bottom of the article.

Quick solution, more a POC than anything else.

😎

USE tempdb;

GO

DECLARE @TSTR NVARCHAR(200) = N'<TV<MR1#4.0#true#2.0#USD>VT>,<TV<MR2#3.0#true#1.5#USD>VT>,<TV<MR3#0.0#true#0.0#USD>VT>,<TV<MR4#0.375#true#0.19#USD>VT>';

DECLARE @SQL_STR NVARCHAR(MAX) = N''

SELECT @SQL_STR = N'select [Model Code],[Persentage],[isAbs],[AppliedValue],[Currency] from (values '

+ REPLACE(REPLACE(REPLACE(@TSTR,N'<TV<',N'('''),N'>VT>',N''')'),N'#',N''',''') + N') as X([Model Code],[Persentage],[isAbs],[AppliedValue],[Currency]);';

EXEC (@SQL_STR);

Results

Model Code Persentage isAbs AppliedValue Currency

---------- ---------- ----- ------------ --------

MR1 4.0 true 2.0 USD

MR2 3.0 true 1.5 USD

MR3 0.0 true 0.0 USD

MR4 0.375 true 0.19 USD
