SQL 2012 :: Removing Consecutive Characters From Middle Of A String
Apr 14, 2015
I usually do this through Access so I'm not too familiar with the string functions in SQL. My question is, how do you remove characters from the middle of a string?
Ex:
String value is 10 characters long.
The string value is X000001250.
The end result should look like, X1250.
I've tried mixing/matching multiple string functions with no success. The only solution I have come up with removes ALL of the zeros, including the tailing zero. The goal is to only remove the consecutive zeroes in the middle of the string.

I have a varchar field which contains some Greek characters (α, β, γ, etc...) among the regular Latin characters. I need to replace these characters with a word (alpha, beta, gamma etc...). When I try to do this, I find that it is also replacing some of the Latin characters.
DECLARE @Letters TABLE (Letter NVARCHAR(10))
INSERT INTO @Letters VALUES ('a'), ('A'), ('b'), ('B'), ('α')
SELECTLetter, REPLACE(Letter,'α','alpha')
FROM@Letters
In this case, the "α" is being replaced, but so are "a" and "A".
I have tried changing the datatype from varchar to nvarchar and also changing the collation.

Hi,
I was wondering what would be the best way to remove special characters like, '-', '&' '(',')','#','*', etc... from a number string. To be specific a phone Number string where the string is >= 10.
Thanks, Mark

I have a string 'ACDIPFJZ'
In my table one of the column has data like
PFAG
ABCDEFHJMPUYZ
KML
JC
RPF
My requirement is that if the string in the column has any of the characters from 'ACDIPFJZ' , those characters have to be retained and the rest of the characters have to be removed.
My output should be:
PFAG -- PFA (G Eliminated)
ABCDEFHJMPUYZ -- ACDPFJZ (B,E,H,M,U,Y Eliminated)
KML -- No data
JC -- JC
RPF -- PF (R Eliminated)

I need to build a query, or use a function to removing alfabetic Character from a string.
My string is
WI14000323-0003
The value i want to keep is : 14000323-0003.
I try using this SELECT:
SELECT STUFF(Upper(z.lote), PATINDEX('%[A-Z]%', Upper(z.lote)), 2, '') from mytable
but in this case i have only 2 letters WI, but in the future i dont know if is only 2 letters, 1 letter or more, then is not what i pretend.

I need extracting string that is between certain characters that are in certain position.
Here is the DDL:
DROP TABLE [dbo].[StoreNumberTest]
CREATE TABLE [dbo].[StoreNumberTest](
[StoreNumber] [varchar](50) NULL,
[StoreNumberParsed] [varchar](50) NULL)
INSERT INTO [dbo].[StoreNumberTest]
[Code] ....
What I need to accomplish is to extract the string that is between the third and fifth '-' (dash) and insert it into the StoreNumberParsed while eliminating the fourth dash.
Sample output would be:
KY117
CA132
OH174
MD163
FL191
I know that parse, charindex, patindex all might come in play, but not sure how to construct the statement.

I am trying to count the characters in a sting before a space. Here is the example of what I am trying to accomplish.
"2073 9187463 2700' 4 7 4, the string character count is 4 before the space, 7 is the count before the next space and the last is the last in the string, if there was more characters within this string for example....'2073 9187463 2700 7023 6044567' it would return the number of characters in the string before the space and at the very end of it.

I am looking for the fastest way to strip non-numeric characters from a string.
I have a user database that has a column (USER_TELNO) in which the user can drop a telephone number (for example '+31 (0)12-123 456'). An extra computed column (FORMATTED_TELNO) should contain the formatted telephone number (31012123456 in the example)
Note: the column FORMATTED_TELNO must be indexed, so the UDF in the computed column has WITH SCHEMABINDING.... I think this implicates that a CLR call won't work....

I have a problem where I want to write a function to remove recurring characters from a string and replace them with a single same character.
For instance I have the string '12333345566689' and the result should be '12345689'. In Oracle I could do this with "regexp_replace('12333345566689', '(.)1+', '1')", but in T-SQL the only solution I could think of is something like this:
DECLARE @code NVARCHAR(255)
SET @code = '12333345566689';
SET @code = REPLACE(REPLACE(REPLACE(@Code, '1', '~1'), '1~', ''), '~1', '1');
and repeat this for 2 - 9. But I'm sure there is a more elegant version for this in SQL Server 2012.

Hello all,
I have a table named users. It consists of user names, user ids, etc... The problem is that whoever designed the ASP code before me allowed people to enter info in any format they want. This poses a problem because now the name can have 1, 2, or sometimes 3 spaces in between the last and first names. And sometimes the middle initial is used with a period following it. This creates problems when I am trying to execute a Select statement since it won't match if there are an unknown number of spaces in the string and throws an error when a period is used.
Is there a SQL query I can execute to change all the user_names into a format such as the following:
LastName, FirstName MiddleInitial
Like I said, it is already almost the same, just has too many spaces and some have periods after the middle initial

Folks ... I have a pipe-delimited ASCII text file with a lot ofdifferent non-printing characters. Rather than try and figure out allthe non-printing characters that exist in this 17+ million recorddatabase, I was hoping someone might have already written a scriptthey'd be willing to share that would remove all non-printingcharacters from an ASCII file?Thanks,Ralph NobleJoin Bytes!

I am trying to write a query in sql query analyzer that will extract a date that appears after the first comma in the string. An example of the data is below:
DAVE,12/31/03,17:18,PERIODENDP
AS,01/16/06,16:51,CUSTOMERS_VW
EM,11/09/07,15:08,ORDER_ENTRY_
I want to select the 8 characters after the first comma in the field, and then convert it to a date format.
I am a novice, so any help with the correct function and syntax would be greatly appreciated.
thanks,

Hello,
I am using the following expression to strip the last 11 characters in a field group and it returns an error saying that Len cannot use a negative number. It must be 0 or greater. Is there a better alternative?

Problem 1: I have the following table which shows the location of a person at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexdelta
11MickeyClub house03001
21MickeyClub house04001
31MickeyPark05002
41MickeyMinnies Boutique06003
51MickeyMinnies Boutique07003
61MickeyClub house08004
71MickeyClub house09004
81MickeyPark10005
91MickeyClub house11006
The delta increments by +1 every time the location changes.
I would like to return an aggregate grouped by delta as per example below.
EntityNameLocationIDStartTimeEndTime
MickeyClub house03000500
MickeyPark05000600
MickeyMinnies Boutique06000800
MickeyClub house08001000
MickeyPark10001100
MickeyClub house11001200
I am using the following query (which works fine):
select
min(timex) as start_date
,end_date
,entityid
,entityname
,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2:I have the following table which shows the location of different people at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexDelta
11MickeyClub house09001
21MickeyClub house10001
31MickeyPark11002

52DonaldPark10002
62DonaldPark11002
73GoofyPark09001
83GoofyClub house10002
93GoofyPark11003
I would like to return an aggregate grouped by person and location.
For example
EntityIDEntityNameLocationIDStartTimeEndTime
1MickeyClub house09001100
1MickeyPark11001200
2DonaldClub house09001000
2DonaldPark10001200
3GoofyPark09001000

I have a table with several columns of information that I wish to set up some form of schedule to go through this data and remove any special characters that may interfere with other code processes.
Mainly the coma's and the apostrophes. It really messes with my asp pages and scripts when retrieving this information and trying to do other things with it, so I need to figure out how to remove these from the tables so it does not cause these issues.
Knowing this, I cannot figure out how to keep the data in the row/column and just extract the special characters from that data. The other problem is, everything I try requires me to insert either a coma or apostrophe as part of the code string which in lies my issue.
How can I parse through my data, leave the data as-is, but just get rid of coma's, apostrophes, and double quotes?
Does anyone have a basic example that I can use to expand on?

Hi I am trying to strip out any non-alpha characters from a field.
i.e. Field = ABC"_IT8*$ should return: ABCIT8
I am writing a loop to do this for all values of a field. The script runs, but hangs....please could somebody advise on the code below...:
I run the script but it doesn't seem to finish. Can anybody see any issues with the code:
DECLARE @Index SMALLINT,
@MATCH_Supplier_name varchar(500),
@Counter numeric,
@Max numeric
-- @sqlstring varchar(500)
SET @Counter = 1
SET @Max = (SELECT Max(DTect_Supplier_SRN) FROM SUPPLIER_TABLE_TEST)
WHILE @Counter <@Max
BEGIN
SET @MATCH_Supplier_name = (SELECT Match_Supplier_Name FROM SUPPLIER_TABLE_TEST WHERE @Counter = DTect_Supplier_SRN)
SET @Index = LEN(@MATCH_Supplier_name)
WHILE @Index > = 1
SET @MATCH_Supplier_name = CASE
WHEN SUBSTRING(@MATCH_Supplier_name, @Index, 1) LIKE '[a-zA-Z]' TH EN SUBSTRING(@MATCH_Supplier_name, @Index, 1)
WHEN SUBSTRING(@MATCH_Supplier_name, @Index, 1) LIKE '[0-9]' THEN SUBSTRING(@MATCH_Supplier_name, @Index, 1)
ELSE ''
END + @MATCH_Supplier_name
SET @Index = @Index - 1
--PRINT @MATCH_Supplier_name
SET @Counter = @Counter + 1

Ok following scenario
create table dbo.ADAssets
(Computername nvarchar(max))
insert into dbo.ADAssets
values
('AIRLBEOF3565 CNF:4e926e06-6f62-4864-aebd-6311543d',
'AIRLBEOF3565')
So if execute the following
select Computername
from dbo.ADAssets
where Computername like
'AIRLBEOF3565%'
I get both records,but if I do this
select *
from dbo.ADAssets
where Computername in
(
'AIRLBEOF3565 CNF:4e926e06-6f62-4864-aebd-6311543d',
'AIRLBEOF3565'
)
I only get AIRLBEOF3565
So the big picture is that I need to compare 2 tables to find records that match & don't but that I get matches that shouldn't be & matches that aren't.
