I need to parse the sample data below as shown. Please help me in writing a TSQL Function.
Create Table Ramesh_StringParsing
(
Col1 Varchar (50),
Col2 Varchar(50)
)
Insert Into Ramesh_StringParsing (Col1, Col2)
VALUES ('A123|B3456|G546|V897|', 'Add|Delete|Insert|Update|')
Insert Into Ramesh_StringParsing (Col1, Col2)
VALUES ('C334|','Apple|')
Insert Into Ramesh_StringParsing (Col1, Col2)
VALUES ('R234|U768|X787','Ram|Sam|John')
Insert Into Ramesh_StringParsing (Col1, Col2)
VALUES ('F44|K456', 'Paint|Faint')
My Output should be:
column1column2
A123 Add
B3456Delete
G546 Insert
V897 Update
C334 Apple
R234 Ram
U768 Sam
X787 John
F44 Paint
K456 Faint

Have you tried the 8K Splitter[/url]?

Take a look into well-known J.Moden splitter function http://www.sqlservercentral.com/articles/Tally+Table/72993/

If you cross apply to this function on each column then you can join on ItemNo function return and you will get exact output you want:

select c1.Item, c2.Item

from (select r.Col1, r.Col2, f.*

from Ramesh_StringParsing as r

cross apply dbo.DelimitedSplit8k(r.Col1, '|') f) as c1

join (select r.Col1, r.Col2, f.*

from Ramesh_StringParsing as r

cross apply dbo.DelimitedSplit8k(r.Col2, '|') f) as c2

on c2.PosNo = c1.PosNo

and c2.Col1 = c1.Col1

and c2.Col2 = c1.Col2

where c1.Item != '' or c2.Item != ''

Please note, as you didn't ptovide any indication of the keys in your sample table, my example joins on Col1 and Col2. I hope in real life you have some PK in this table - you better to join on it (you will need to list PK column(s) in sub-queries).

Thanks a lot guys for quick reply.

What does PosNo Stands for in your Code below?

on c2.PosNo = c1.PosNo

In the original function it's returned as ItemNumber instead of PosNo

Yeah, I have slightly modified version in my play-ground. As per Luis point, just replace PosNo with ItemNumber and query should work.
