I need to create a consecutive sequence of varchar(5) (always 5 chars only) code starting from PREVIOUS code.
For example
'00000', '00001', '00002'...'00009', '0000A', '0000B'...'0000Z', '00010','00011'...'ZZZZZ'.
So if I have #PREVIOUS_CODE = '00000', #NEXT_CODE will be '00001'.
If I have #PREVIOUS_CODE = '00009', #NEXT_CODE will be '0000A'
If I have #PREVIOUS_CODE = '0000Z', #NEXT_CODE will be '00010'
So I need something like that
USE [DATABASE]
GO
CREATE PROCEDURE [dbo].[spGetNextCode]
#PREVIOUS_CODE VARCHAR(5)
AS
DECLARE #NEXT_CODE VARCHAR(5)
DO STUFF
...
SELECT #NEXT_CODE AS NEXT_CODE
GO
Any Help?
Just keep an integer counter in the same table and convert it. I'm using the following SQL Server function in one of my applications:
CREATE FUNCTION [dbo].[GetAlphanumericCode]
(
#number BIGINT,
#leadingzeroes INT = 0
)
RETURNS varchar(255)
AS
BEGIN
DECLARE #charPool varchar(36)
SET #charPool = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'
DECLARE #result varchar(255)
IF #number < 0
RETURN ''
IF #number = 0
SET #result = '0'
ELSE BEGIN
SET #result = ''
WHILE (#number > 0)
BEGIN
SET #result = substring(#charPool, #number % 36 + 1, 1) + #result
SET #number = #number / 36
END
END
IF #leadingzeroes > 0 AND len(#result) < #leadingzeroes
SET #result = right(replicate('0', #leadingzeroes) + #result, #leadingzeroes)
RETURN #result
END
It should be a trivial task to rewrite it as a stored procedure

I'm looking at pulling two numeric values from a single text string in SQL (2012 version i believe).
The strings are in the following possible formats:
A1234 B4567
or
A:1234 B:4567
or random variants of
A[Symbol/Space/Nothing][Numberstring1] [Space/Nothing] B[Symbol/Space/Nothing][Numberstring2]
Ideally I'd use a combo of substring and charindex but because the symbols/space/nothing at all are used at random i'm finding it difficult.
My preferred output would be 2 columns, one with the [NumberString1] one with [Numberstring2]
Any ideas folks?
You could give this approach a try, it will give you a list of all the number groups. You could then select from the resulting table.
CREATE FUNCTION [dbo].[ParseOutNumbers](#inputText varchar(1000))
RETURNS #ParsedValues TABLE (ID int IDENTITY(1,1),numVal varchar(1000))
AS
BEGIN
DECLARE #charIndex INT
DECLARE #number varchar(1000)
DECLARE #nextChar varchar(1000)
SELECT #charIndex = 1
SELECT #number = ''
WHILE #charIndex <= LEN(#inputText)
BEGIN
SELECT #nextChar = SUBSTRING(#inputText, #charIndex, 1);
IF ISNUMERIC(#nextChar) = 1
BEGIN
SELECT #number = #number + #nextChar
END
IF (ISNUMERIC(#nextChar) = 0 OR #charIndex = LEN(#inputText))
BEGIN
IF (LEN(#number) > 0)
BEGIN
INSERT #ParsedValues(numVal) VALUES(#number)
SELECT #number = ''
END
END
SELECT #charIndex = #charIndex + 1
END
RETURN
END
GO

Alternate version:
CREATE FUNCTION [dbo].[ParseOutNumbersRev2](#inputText varchar(1000))
RETURNS #ParsedValues TABLE (A varchar(1000), B varchar(1000))
AS
BEGIN
DECLARE #charIndex INT
DECLARE #number varchar(1000)
DECLARE #nextChar varchar(1000)
DECLARE #valueIndex INT
SELECT #charIndex = 1
SELECT #number = ''
SELECT #valueIndex = 0
WHILE #charIndex <= LEN(#inputText)
BEGIN
SELECT #nextChar = SUBSTRING(#inputText, #charIndex, 1);
IF ISNUMERIC(#nextChar) = 1
BEGIN
SELECT #number = #number + #nextChar
END
IF (ISNUMERIC(#nextChar) = 0 OR #charIndex = LEN(#inputText))
BEGIN
IF (LEN(#number) > 0)
BEGIN
IF (#valueIndex = 0)
BEGIN
INSERT #ParsedValues(A, B) VALUES(#number, null)
END
ELSE IF (#valueIndex = 1)
BEGIN
UPDATE #ParsedValues SET B = #number
END
SELECT #number = ''
SELECT #valueIndex = #valueIndex + 1

I'm using #subno as Input. And I had to find the odd and even numbers. 16 is not a fix and it can be any other number. My question is how to find the odd and even number of my input?
Lastly, subno includes ( . ) dot at any position. e.g 123456.789123 I need to find the odd and even number of "123456" and the odd and even number of "789123" the dot ( . ) is the separator.
Once you find the odd for the left side, sum them up together. Once you find the even number for left side sum it up as well and then add the total odd to the total even values. That goes the same for the right side eg "789123".
Please help me. this is my 2nd week of trying to find the solution. Once you find all the total values for each side, multiply them together. example "123456" - total value of odd and even * the "789123" total value of odd and even.
It is for the the check digit validation. Validating the subscriber number. after validating through the calculation it should match the calculated reference number to the valid check digit number. It's the business rule. Kind of algorithm
create procedure ProcedureName
(#subno VARCHAR(16), --Input the 16 subscriber number
#result INT OUT,

Split the values which u get . Then iterate iver each side and add them. Please see the sample below.

I want to find a credit card numeric value in a sql string.
for example;
DECLARE #value1 NVARCHAR(MAX) = 'The payment is the place 1234567812345678'
DECLARE #value2 NVARCHAR(MAX) = 'The payment is the place 123456aa7812345678'
DECLARE #value3 NVARCHAR(MAX) = 'The payment1234567812345678is the place'
The result should be :
#value1Result 1234567812345678
#value2Result NULL
#value3Result 1234567812345678
16 digits must be together without space.
How to do this in a sql script or a function?
edit :
if I want to find these 2 credit card value.
#value4 = 'card 1 is : 4034349183539301 and the other one is 3456123485697865'
how should I implement the scripts?
You can use PathIndex as
PATINDEX('%[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]%', yourStr)
if the result is 0 then it doesnt containg 16 digits other was it contains.
It can be used withing a Where statement or Select statement based on your needs
You can write as:
SELECT case when Len(LEFT(subsrt, PATINDEX('%[^0-9]%', subsrt + 't') - 1)) = 16
then LEFT(subsrt, PATINDEX('%[^0-9]%', subsrt + 't') - 1)
else ''
end
FROM (
SELECT subsrt = SUBSTRING(string, pos, LEN(string))
FROM (
SELECT string, pos = PATINDEX('%[0-9]%', string)
FROM table1
) d
) t
Demo
DECLARE #value1 NVARCHAR(MAX) = 'card 1 is : 4034349183539301 and the other one is 3456123485697865'
DECLARE #Lenght INT
,#Count INT
,#Candidate CHAR
,#cNum INT
,#result VARCHAR(16)
SELECT #Count = 1
SELECT #cNum = 0
SELECT #result = ''
SELECT #Lenght = LEN(#value1)
WHILE #Count <= #Lenght
BEGIN
SELECT #Candidate = SUBSTRING(#value1, #Count, 1)
IF #Candidate != ' '
AND ISNUMERIC(#Candidate) = 1
BEGIN
SET #cNum = #cNum + 1
SET #result = #result + #Candidate
END
ELSE
BEGIN
SET #cNum = 1
SET #result = ''
END
IF #cNum > 16
BEGIN
SELECT #result 'Credit Number'
END
SET #Count = #Count + 1
END
There you go kind sir.
DECLARE
#value3 NVARCHAR(MAX) = 'The payment1234567812345678is the place',
#MaxCount int,
#Count int,
#Numbers NVARCHAR(100)
SELECT #Count = 1
SELECT #Numbers = ''
SELECT #MaxCount = LEN(#value3)
WHILE #Count <= #MaxCount
BEGIN
IF (UNICODE(SUBSTRING(#value3,#Count,1)) >= 48 AND UNICODE(SUBSTRING(#value3,#Count,1)) <=57)
SELECT #Numbers = #Numbers + SUBSTRING(#value3,#Count,1)
SELECT #Count = #Count + 1
END
PRINT #Numbers
You can make this as a function if you are planning to use it a lot.
I have several occurrences of differences strings in the columns, like this example
'dsasdasdsd'+'ewewewew'+'45454545'+(avg('uuuuuuu'))
I need to split this string into several columns with the substrings that are between
aphostropes
like this:
Column 1 = dsasdasdsd
Column 2 = ewewewew
Column 3 = 45454545
Column 4 = uuuuuuu
The numbers of apperances are random, thefore the length of the original column is also not fixed (from 50 char to > 1000)
DECLARE #InStr VarChar(1000) = '''dsasdasdsd''+''ewewewew''+''45454545''+(avg(''uuuuuuu''))'''
DECLARE #intStart INT = 0
DECLARE #intEnd INT = 1
DECLARE #ColNo INT = 1
DECLARE #MyString VARCHAR(2000)
DECLARE #SelectString VARCHAR(8000) = 'SELECT '
WHILE(#intStart < LEN(#InStr) )
BEGIN
SELECT #intStart = CHARINDEX(CHAR(39), #InStr, 0) + 1
SELECT #intEnd = CHARINDEX(CHAR(39), #InStr, #intStart)
SELECT #SelectString = #SelectString + CHAR(39) + SUBSTRING(#InStr, #intStart, #intEnd - #intStart) + CHAR(39) + ' As [Column ' + CAST(#ColNo As Varchar) + '],'
SELECT #InStr = SUBSTRING(#InStr, #intEnd + 1, LEN(#InStr)-#intEnd )
SET #ColNo = #ColNo +1
END
SELECT #SelectString = LEFT(#SelectString, Len(#SelectString) -1)
EXEC (#SelectString)
I have been playing with this and this does run but unfortunately I don't have time right now to carry on with it but maybe you can improve on this?
HTH
You can try this:
create table tSqlStrings (sText nvarchar(1000))
insert tSqlStrings values('''dsasdasdsd''+''ewewewew''+''45454545''+(avg(''uuuuuuu''))')
create table tResults (
sColumn1 nvarchar(1000)
,sColumn2 nvarchar(1000)
,sColumn3 nvarchar(1000)
,sColumn4 nvarchar(1000)
)
and
DELETE tResults
DECLARE #sText nvarchar(1000) = (
SELECT
sText
FROM
tSqlStrings
)
DECLARE #lBegin int = CHARINDEX('''',#sText)
DECLARE #lEnd int = charindex('''',
substring(#sText,

INSERT

VALUES (#sColumn1,#sColumn2,#sColumn3,#sColumn4)
SELECT * FROM tResults

You will be able to achieve this using CHARINDEX() and SUBSTRING()
Following example shows for splitting to 2 columns. When it has more columns, query will be get little more complicated. However, you can follow this to build your query.
SELECT OriginalColumn
, SUBSTRING(OriginalColumn, 1,CHARINDEX('x',OriginalColumn,1)-1) AS Column1
, SUBSTRING(OriginalColumn, CHARINDEX('x',OriginalColumn,1) + 1 ,CHARINDEX('x',OriginalColumn,CHARINDEX('x',OriginalColumn,1)-1)) AS Column2
FROM YourTable
I have used "x" as the delimiter in the example. Following is a sample result
try this:
declare #delim char
set #delim = ''''
declare #str nvarchar(max)
declare #substr nvarchar(max)
declare #newstr nvarchar(max)
declare #tmpTable table (partStrings nvarchar(max))
declare #count int
set #count = 0
select #str = <***Your String***>
while(charindex(#delim,#str) != 0)
begin
set #count = #count + 1
Select #substr = substring(#str,1,charindex(#delim,#str)-1)
if((#count % 2) = 0)
begin
insert into #tmpTable values(#substr)
end
Set #newstr = substring(#str,charindex(#delim,#str)+1,len(#str)-charindex(#delim,#str))
set #str = #newstr
end
select partStrings from #tmpTable
Given a number, how do you convert that to letters?
You can just translate your existing logic into a t-sql scalar function, like so:
CREATE FUNCTION dbo.fnColumnNameFromIndex(#i int)
RETURNS varchar(3)
AS
BEGIN
DECLARE #dividend int, #letters varchar(3), #modulo int
SET #dividend = #i
SET #letters = ''
WHILE #dividend > 0
BEGIN
SET #modulo = (#dividend - 1) % 26
SET #letters = CHAR(65 + #modulo) + #letters
SET #dividend = CONVERT(int, (#dividend - #modulo) / 26 )
END
RETURN #letters;
END
GO
Call it like this:
SELECT dbo.fnColumnNameFromIndex(2000)
...admittedly not set logic, but I don't see this as a set logic problem.
