How to split value to another column? - sql

Question

I have data input and want output in picture. How do I to write it?
i can run in sql server for this but i get only width column( w_pacakaging) , but i dont know to write get value length or high from column text (db name : [Packing list text])
my code is
select [Packing list text],[Grade],[sales doc no],
case when [Packing list text] like'%:%' then
cast(Ltrim(Rtrim(SUBSTRING([Packing list text], charindex(':', [Packing list text]) + 1, charindex('"', [Packing list text])
- (charindex(':', [Packing list text]) + 1)))) as [nvarchar] )
END AS [W_packaging]
from [TPC_CRSYS].[dbo].[TotalOrder_Export]
the result from sql server
enter image description here
How could you advice me for write sql to get data for length and heigh from table [TotalOrder_Export] because it has more than one x in each record
could anyone advice me

Answer 1

the easy way using CTE and CHARINDEX:
;with
T AS ( -- select the base table, adding an index for performances pourpose
SELECT *, ROW_NUMBER() OVER (ORDER BY [sales doc no],[Packing list text]) ROW_IDX
FROM [TPC_CRSYS].[dbo].[TotalOrder_Export]
),
W AS (-- SELECT ONLY ROWS WITH VALID DIMENSIONS AND CALC WIDTH POSITION
SELECT *, CHARINDEX('(WXLXH): ', [Packing list text])+9 W_POS
FROM T
WHERE CHARINDEX('(WXLXH): ', [Packing list text])>0
),
L AS (-- CALC LENGTH POSITION
SELECT *, CHARINDEX('"', [Packing list text], W_POS)+2 L_POS
FROM W
),
H AS (-- CALC HEIGHT POSITION
SELECT *, CHARINDEX('"', [Packing list text], L_POS)+2 H_POS
FROM L
),
X AS (-- CALC
SELECT *, CHARINDEX('"', [Packing list text], H_POS) END_POS
FROM H
)
SELECT T.[Packing list text], T.grade, T.[sales doc no]
, SUBSTRING(T.[Packing list text], W_POS, L_POS-2-W_POS) W
, SUBSTRING(T.[Packing list text], L_POS, H_POS-2-L_POS) L
, SUBSTRING(T.[Packing list text], H_POS, END_POS-H_POS) H
FROM T
LEFT JOIN X ON T.ROW_IDX = X.ROW_IDX
alternatively, you can use OUTER APPLY and a split (FN_SPLIT) function to get w/h/l in rows for each [Packing list text], and then PIVOT them back to one single line:
;with
T AS ( -- select the base table, adding an index for performances pourpose
SELECT *, ROW_NUMBER() OVER (ORDER BY [sales doc no], [Packing list text]) ROW_IDX
FROM [TPC_CRSYS].[dbo].[TotalOrder_Export]
),
W AS (-- SELECT ONLY ROWS WITH VALID DIMENSIONS AND CALC WIDTH POSITION
SELECT *, CHARINDEX('(WXLXH): ', [Packing list text])+9 W_POS
FROM T
WHERE CHARINDEX('(WXLXH): ', [Packing list text])>0
),
spl as (
select W.ROW_IDX, d.*
from w
outer apply (
select ID, SUBSTRING(data,2,100) VAL
from FN_SPLIT(SUBSTRING(w.[Packing list text], w_pos-1, 100),'"') s
where s.id<=3
) d
),
X AS (
SELECT *
FROM spl
PIVOT (MIN(VAL) FOR ID IN ([1],[2],[3])) P
)
SELECT T.[Packing list text], T.grade, T.[sales doc no], X.[1] W, X.[2] L, X.[3] H
FROM T
LEFT JOIN X ON T.ROW_IDX = X.ROW_IDX
this second version is faster if you have many rows in your [TotalOrder_Export] table
for the split function, you will find many versions around, I made this:
CREATE FUNCTION [dbo].[FN_SPLIT]
(
#Line varchar(8000),
#SplitOn varchar(10) = ','
)
RETURNS #RtnValue table
(
Id INT NOT NULL IDENTITY(1,1) PRIMARY KEY CLUSTERED, -- VERY USEFUL TO MAKE JOINS AND TO CREATE THE UNIQUE INDEX ON SPLITTED STRINGS
Data varchar(800) NOT NULL,
UNIQUE (DATA, ID) -- THIS WILL MAKE REALLY FASTER THE QUERIES USING THIS FUNCTION
)
AS
BEGIN
IF #Line IS NULL RETURN
DECLARE #split_on_len INT = LEN(#SplitOn+'X')-1 -- TO CATCH TRAILING SPACES PROBLEM WITH LEN()
DECLARE #line_len INT = LEN(#line+'X')-1
DECLARE #start_at INT = 1
DECLARE #end_at INT
DECLARE #data_len INT
WHILE 1=1
BEGIN
IF #start_at > #line_len BREAK;
SET #end_at = CHARINDEX(#SplitOn, #Line, #start_at)
SET #data_len = CASE #end_at WHEN 0 THEN #line_len ELSE #end_at-#start_at END
INSERT INTO #RtnValue (data) VALUES( SUBSTRING(#Line,#start_at,#data_len));
SET #start_at = #start_at + #data_len + #split_on_len
END
RETURN
END
I hope this helps
