I need to create this table function. The function needs to return single words from passed parameters like: hello, hhuu, value
The table function should return:
hello,
hhuu,
value
But I am always getting some errors, please could you help me?
you can write as:
DECLARE #input_char VARCHAR(255)
SET #input_char = 'hello, hhuu, value'
;WITH cte AS (
SELECT
CAST('<r>' + REPLACE(#input_char, ' ', '</r><r>') + '</r>' AS XML) AS input_char
)
SELECT
rtrim( LTRIM (xTable.xColumn.value('.', 'VARCHAR(MAX)')) ) AS input_char
FROM cte
CROSS APPLY input_char.nodes('//r') AS xTable(xColumn)
Please give a look at this article:
http://www.codeproject.com/Tips/625872/Convert-a-CSV-delimited-string-to-table-column-in
and you could use ' ' (space) as delimiter.
SELECT * FROM dbo.CSVtoTable('hello, hhuu, value', ' ')
I have used the following function many times. It is a bit lengthy forgive me, but it has become a great tool for me.

I have my table like this

I want to split every row to be like this
4-3-2
10
12-10

try this
DECLARE #table AS TABLE

You can use a function in case you need the query to be simple
Function
CREATE FUNCTION [dbo].[ConvertToNumber]
(#strAlphaNumeric VARCHAR(256))
RETURNS VARCHAR(256)
AS
BEGIN
SET #strAlphaNumeric = LEFT(#strAlphaNumeric,
LEN(#strAlphaNumeric) - CHARINDEX('-', REVERSE(#strAlphaNumeric)) + 0)
DECLARE #intAlpha INT
SET #intAlpha = PATINDEX('%[^0-9]-%', #strAlphaNumeric)
BEGIN
WHILE #intAlpha > 0
BEGIN
SET #strAlphaNumeric = STUFF(#strAlphaNumeric, #intAlpha, 1, '' )
SET #intAlpha = PATINDEX('%[^0-9]-%', #strAlphaNumeric )
END
END
RETURN ISNULL(#strAlphaNumeric,0)
END
And your final query
SELECT DBO.ConvertToNumber(STRINGCOLUMN)STRINGCOLUMN
FROM #TEMP
RESULT
first use this split func
CREATE FUNCTION [dbo].[fnSplitString] ( #string NVARCHAR(MAX)
, #delimiter CHAR(1) )
RETURNS #output TABLE ( splitdata NVARCHAR(MAX) )
BEGIN
DECLARE #start INT
, #end INT
SELECT #start = 1
, #end = CHARINDEX(#delimiter, #string)
WHILE #start < LEN(#string) + 1
BEGIN
IF #end = 0
SET #end = LEN(#string) + 1
INSERT INTO #output ( splitdata )
VALUES ( SUBSTRING(#string, #start, #end - #start) )
SET #start = #end + 1
SET #end = CHARINDEX(#delimiter, #string, #start)
END
RETURN
END
and then use this code
CREATE TABLE #t10 ( id int identity(1,1)
, num int )
INSERT INTO #t10
select *
from dbo.fnSplitString ('4-Documento d’identità-3-Attestato di Rischio-2-Carta di Circolazione','-')
WHERE ISNUMERIC(splitdata)=1
DECLARE #x int = 1
DECLARE #y varchar(10)=''
DECLARE #q varchar(10)
WHILE #x<=(SELECT count(*)
from #t10)
BEGIN
SET #q=(SELECT num
FROM #t10
WHERE id = #x )
set #y=#y+#q+'-'
SET #x=#x+1
END
SELECT left(ltrim(#y),len(#y)-1)
--SELECT * FROM #t10
--drop table #t10
It's a bit messy, but it gets the job done :-)
CREATE TABLE dbo.Documents (
Details VARCHAR(1000)
);
GO
INSERT INTO dbo.Documents
VALUES ('4-Documento d’identità-3-Attestato di Rischio-2-Carta di Circolazione'),

SELECT CASE WHEN (FirstLine + SecondLine + ThirdLine) LIKE '%-'
THEN LEFT(FirstLine + SecondLine + ThirdLine, LEN(FirstLine + SecondLine + ThirdLine) -1)
ELSE (FirstLine + SecondLine + ThirdLine) END AS CleanData
FROM (
SELECT
LEFT(Details, CHARINDEX('-', Details)) AS FirstLine,
REPLACE(CASE

END , LEFT(Details, CHARINDEX('-', Details)), '') AS SecondLine,

THEN LEFT(REVERSE(LEFT(REVERSE(Details), CHARINDEX('-', REVERSE(Details))+2)), 3) ELSE '' END AS ThirdLine
FROM dbo.Documents
) AS A;
Another way of doing it in a much simpler way. Create a function to remove the alphabets from the string
Create FUNCTION dbo.RemoveAlphabets (#string VARCHAR(256))
returns VARCHAR(256)
BEGIN
IF #string IS NULL
RETURN NULL
DECLARE #Result VARCHAR(256)='',#len INT = Len(#string ),#cnt INT=1
WHILE #cnt <= #len
BEGIN
DECLARE #parse INT
SET #parse = Ascii(Substring(#string , #cnt, 1))
IF #parse BETWEEN 48 AND 57 or #parse =45
SET #Result = #Result + Char(#parse)
SET #cnt = #cnt + 1
END
select #result= replace(#Result,'--','-')
RETURN left(#result,case when right(#Result,1)='-' then len(#Result)-1 else len(#result) end)
END
If numbers inside the string is always surrounded by '-' then replace the return statement with this.
RETURN left(#result,len(#Result)-1)
execute the function
select dbo.RemoveAlphabets
('4-Documento d’identità-3-Attestato di Rischio-2-Carta di Circolazione')
Result : 4-3-2
I just had to scour the internet for this code yet again so I figured I would put it here so I can find it a little faster the next time and hopefully you found it a little faster too :)
Check this.

SELECT #Index = LEN(#GTIN_strip),
#Multiplier = 3,
#Sum = 0
WHILE #Index > 0
SELECT #Sum = #Sum + #Multiplier * CAST(SUBSTRING(#GTIN_strip, #Index, 1) AS TINYINT),
#Multiplier = 4 - #Multiplier,
#Index = #Index - 1
SELECT #checksum = CASE #Sum % 10
WHEN 0 THEN '0'
ELSE CAST(10 - #Sum % 10 AS CHAR(1))
END
IF (SUBSTRING(#GTIN,LEN(#GTIN),1) = #checksum)
RETURN 1; /*true*/
RETURN 0; /*false*/
END
CREATE FUNCTION [dbo].[fn_EAN13CheckDigit] (#Barcode nvarchar(12))
RETURNS nvarchar(13)
AS
BEGIN
DECLARE #SUM int , #COUNTER int, #RETURN varchar(13), #Val1 int, #Val2 int
SET #COUNTER = 1 SET #SUM = 0
WHILE #Counter < 13
BEGIN
SET #VAL1 = SUBSTRING(#Barcode,#counter,1) * 1
SET #VAL2 = SUBSTRING(#Barcode,#counter + 1,1) * 3
SET #SUM = #VAL1 + #SUM
SET #SUM = #VAL2 + #SUM
SET #Counter = #Counter + 2;
END
SET #SUM=(10-(#SUM%10))%10
SET #Return = #BARCODE + CONVERT(varchar,((#SUM)))
RETURN #Return
END
And here's a MySQL implementation as well.
Note it requires a 13 digit UPC/EAN13 as input, so you should LPAD your input as required.
drop function if exists barcodify;
delimiter //
at the last digit.
create function barcodify(upc varchar(15))
returns varchar(15)
sql security invoker
begin
declare i, r, odd, even,result int;
set odd=0;
set even =0;
set i = length(upc);
while i > 0 do
set r = substring(upc, i, 1) ;
if(i % 2 >0) then set odd = odd + r;
else set even = even + r;
end if;
set i = i - 1;
end while;
set result = (3*odd)+even;
if result % 10 =0 then return 0;
else return (10 - (result %10));
end if;
end //
delimiter ;

declare #xml xml

select N.value('value[1]', 'int') as obj_id,
N.value('value[2]', 'int') as obj_type
from #xml.nodes('item') as T(N)
SQL Fiddle
You can wait for some experts answer
till then you can give it one chance
insert into #tbl
SELECT LEFT(splitdata, CHARINDEX(':', splitdata) - 1) AS obj_id,
RIGHT(splitdata, CHARINDEX(':', REVERSE(splitdata)) - 1) AS obj_type from (select splitdatafrom fnSplitString(parameterName,'|')
now you can write stringsplit function like this
CREATE FUNCTION [dbo].[fnSplitString]
(
#string NVARCHAR(MAX),
#delimiter CHAR(1)
)
RETURNS #output TABLE(splitdata NVARCHAR(MAX)
)
BEGIN
DECLARE #start INT, #end INT
SELECT #start = 1, #end = CHARINDEX(#delimiter, #string)
WHILE #start < LEN(#string) + 1 BEGIN
IF #end = 0
SET #end = LEN(#string) + 1
INSERT INTO #output (splitdata)
VALUES(SUBSTRING(#string, #start, #end - #start))
SET #start = #end + 1
SET #end = CHARINDEX(#delimiter, #string, #start)
END
RETURN
END
Another Solution :
Create FUNCTION [dbo].[SplitString]
(
#List NVARCHAR(MAX),
#Delim VARCHAR(255)
)
RETURNS TABLE
AS
RETURN ( SELECT [Value] FROM
(
SELECT
[Value] = LTRIM(RTRIM(SUBSTRING(#List, [Number],
CHARINDEX(#Delim, #List + #Delim, [Number]) - [Number])))
FROM (SELECT Number = ROW_NUMBER() OVER (ORDER BY name)
FROM sys.all_objects) AS x
WHERE Number <= LEN(#List)
AND SUBSTRING(#Delim + #List, [Number], LEN(#Delim)) = #Delim
) AS y
);
taken form: T-SQL split string
And then select the values:
Declare
#Text varchar (100) = '153:0|114:0|147:0|148:0|152:0|155:0',
#Delim varchar(50) = ':0|'
select case when CHARINDEX(':0', Value) > 0 then Left(Value, Len(Value)-2) else Value End AS Result from dbo.SplitString(#Text, #Delim)

I'm programming a function in SQL 2008R2 that i could give it some parameters like a value varchar, a pattern varchar, a separator char and a filler also char. Then I would like to give the value '22687' with the patter '000.000.000.000', a separator '.' and the filler would be '0', then i would like to expect the function will return '000.000.022.687', does any one have a function already done that can do this?
Something like this:
DECLARE #valor VARCHAR(30)
DECLARE #formato VARCHAR(30)
DECLARE #separador CHAR(1)
DECLARE #rellenarcon CHAR(1)
SELECT #valor = '22959'
SELECT #formato = '000.000.000.000'
SELECT #separador = '.'
SELECT #rellenarcon = '0'
DECLARE #n INTEGER
DECLARE #m INTEGER
DECLARE #i INTEGER
DECLARE #j INTEGER
SELECT #n = LEN(#formato)
SELECT #m = LEN(#valor)
SELECT #i = 1
SELECT #j = 1
DECLARE #res2 varchar(30)
SELECT #res2 = ''
SELECT #valor = REVERSE(#valor)
WHILE #i<=#n
BEGIN
if SUBSTRING(#formato,#i,1) <> #separador
begin
IF #j<=#m
BEGIN
SELECT #res2 = #res2 + SUBSTRING(#valor,#j,1)
SELECT #i=#i+1
SELECT #j=#j+1
END
ELSE
BEGIN
SELECT #res2 = #res2 + #rellenarcon
SELECT #i=#i+1
END
end
else
BEGIN
SELECT #res2 = #res2 + #separador
SELECT #i=#i+1
END
END
print reverse(#res2)
Is a crossover code from java to tsql, the original code in java is:
public static String formatear(String valor, String formato, char separator,
char fillWith, Map<Integer, String> params) {
int n = formato.length() - 1;
int m = valor.length() - 1;
int i = n;
int j = m;
StringBuilder res = new StringBuilder(formato);
for(; i >= 0; i--) {
if(res.charAt(i) != separator) {
if(j >= 0) {
res.deleteCharAt(i);
res.insert(i, valor.charAt(j--));
} else {
res.deleteCharAt(i);
res.insert(i, fillWith);
}
}
}
if(params != null) {
Set<Integer> keys = params.keySet();
for(Integer key : keys) {
i = key;
res.deleteCharAt(i);
res.insert(i, params.get(key));
}
}
return res.toString();
}
The following assumes well-formed inputs, e.g. the value is not longer than the pattern.
declare #Pattern as VarChar(64) = '000.000.000.000';
declare #Fill as Char = '0';
declare #Value as VarChar(64) = '22687';
declare #False as Bit = 0;
declare #True as Bit = 1;
with Gargoyle as (
select #Pattern as Pattern, #Value as Value, Cast( '' as VarChar(64) ) as Buffer,
case when Right( #Pattern, 1 ) = #Fill then #True else #False end as Fill
union all
select
-- Always consume a character from the pattern.
Left( Pattern, Len( Pattern ) - 1 ),
-- Consume a character from the value if the pattern contains fill at the current position.
case
when Fill = #True and Value != '' then Left( Value, Len( Value ) - 1 )
else Value end,
-- Add the correct character to the buffer.
Cast( case when Fill = #True and Value != '' then Right( Value, 1 ) else Right( Pattern, 1 ) end + Buffer as VarChar(64) ),
-- Check the next pattern character for fill.
case
when Len( Pattern ) = 1 then #False
when Substring( Pattern, Len( Pattern ) - 1, 1 ) = #Fill then #True
else #False end
from Gargoyle
where Pattern != ''
)
select Buffer
from Gargoyle
where Pattern = '';
Or, as a function:
create function dbo.PatternFill( #Pattern as VarChar(64), #Fill as Char, #Value as VarChar(64) )
returns VarChar(64)
as
begin
declare #Buffer as VarChar(64) = ''
declare #PatternChar as Char = Right( #Pattern, 1 )
declare #ValueChar as Char = Right( #Value, 1 )
while #Pattern != ''
begin
if #PatternChar = #Fill and #ValueChar != ''
begin
-- Replace a fill character with a value character.
select #Buffer = #ValueChar + #Buffer
if Len( #Value ) > 1
select #Value = Left( #Value, Len( #Value ) - 1 ), #ValueChar = Right( #Value, 1 )
else
select #ValueChar = '', #Value = ''
end
else
begin
-- Copy the pattern character.
select #Buffer = #PatternChar + #Buffer
end
if Len( #Pattern ) > 1
select #Pattern = Left( #Pattern, Len( #Pattern ) - 1 ), #PatternChar = Right( #Pattern, 1 )
else
select #PatternChar = '', #Pattern = ''
end
return #Buffer
end
go
declare #Result as VarChar(64)
declare #Count as Int = 1000000
declare #Start as DateTime = GetDate()
while #Count > 0
select #Result = dbo.PatternFill( '000.000.000.000', '0', '22687' ), #Count = #Count - 1
select #Result as [Result], DateDiff( ms, #Start, GetDate() ) as [Total ms]
1,000,000 iterations on my notebook took 151,656ms, but it's busy BOINCing. That's simple timing with no correction for the time consumed by an empty loop or calling an empty function.
This query will do it:
;with cteZeroPadded(Num) as
(
Select Right('000000000000' + '22687', 12)
)
,cteSplit as
(
Select SUBSTRING(Num, 1, 3) Col1
,SUBSTRING(Num, 4, 3) Col2
,SUBSTRING(Num, 7, 3) Col3
,SUBSTRING(Num, 10, 3) Col4
From cteZeroPadded
)
Select Col1 + '.' + Col2 + '.' + Col3 + '.' + Col4
From cteSplit
In SQLServer2005+ you can use option with recursive CTE
DECLARE #valor varchar(30) = '22959',
#formato varchar(30) = '000000000000000',
#text varchar(30),
#result varchar(30) = N''
SET #text = REVERSE(RIGHT(#formato + #valor, 15))
;WITH cte AS
(
SELECT 1 AS Number, SUBSTRING(#text, 1, 1) AS Num
UNION ALL
SELECT c.Number + 1,
CASE WHEN c.Number IN(3, 7, 11) THEN '.' ELSE
SUBSTRING(#text, CASE WHEN c.Number > 11 THEN c.Number - 2
WHEN c.Number > 7 THEN c.Number - 1
WHEN c.Number > 3 THEN c.Number
ELSE c.Number + 1
END, 1)
END
FROM cte c
WHERE Number < LEN(#text)
)
SELECT #result += c.Num
FROM cte c
ORDER BY Number DESC
SELECT #result
