Stripping Non-Numeric Characters From A String Function
Jul 9, 2002
Hi,
As part of a data search project I need to be able to strip all non numeric characters from a text field. The field contains various forms of phone number in various formats. In order to search on it I am going to remove all non numeric characters from the input criteria and from the data being searched.
In order to do this I decided on using a SQL Server custom function: Pass in field. Loop through all chars, test against asci values for number range. return only numernic data concatenated into a string.
Are there any other more efficient ways of going about this?

Hi there - I would like to share this strip of code with our SQL 2000DBA community. The code below strips all non-numeric characters from agiven string field and rebuilds the string. Very simple, but I had tobuild it from scratch due the lack of info on this specific matter. Iam sure there are better solutions out there, although I will be gladif this script can help anyone. Feel free to modify and comment itback.Regards,Rubem Linn JuniorMCSE, .NET developerWeb Apps Specialist------------------------------------------------------- BEGIN---------------------------------------------------DECLARE @String_Length AS INTEGER -- Length of the given stringDECLARE @Original_String as NVARCHAR(50) -- The field to stripnon-numeric charsDECLARE @counter as integer -- simple counter variableDECLARE @Stripped_String as nvarchar(50) -- The field after beenstripped-- Get the length of the field (string) to be parsedSELECT @String_Length = len(someStringField) FROM SomeTable WHEREFilterID = 001-- Get the field (string) to be parsedSELECT @Original_String = someStringField FROM SomeTable WHEREFilterID = 001-- Set counter variable to 1SELECT @counter = 1-- Reset this variableSELECT @Stripped_String = ''-- Initiate loop from 1 to the Length of the given stringWHILE (@counter) <= @String_LengthBEGIN-- Check if the char in the lap is numericif substring(@Original_String,@counter,1) LIKE '[0-9]'BEGIN-- Load this variable with the non-numeric-- data stripped from the original stringselect @Stripped_String = @Stripped_String +substring(@Original_String,@counter,1)END-- Increment the counter by oneselect @counter = @counter + 1END-- Print the original string with all charactersPRINT @Original_String-- Print the numeric data that was stripped outPRINT RTRIM(LTRIM(@Stripped_String))

Hi,
I was trying to find numeric characters in a field of nvarchar. I looked this up in HELP.
Wildcard
Meaning
%
Any string of zero or more characters.
_
Any single character.
[ ]
Any single character within the specified range (for example, [a-f]) or set (for example, [abcdef]).
Any single character not within the specified range (for example, [^a - f]) or set (for example, [^abcdef]).
Nowhere in the examples below it in Help was it explicitly detailed that a user could do this.
In MS Access the # can be substituted for any numeric character such that I could do a WHERE clause:
WHERE
Gift_Date NOT LIKE "####*"
After looking at the above for the [ ] wildcard, it became clear that I could subsitute [0-9] for #:
WHERE
Gift_Date NOT LIKE '[0-9][0-9][0-9][0-9]%'
using single quotes and the % wildcard instead of Access' double quotes and * wildcard.
Just putting this out there for anybody else that is new to SQL, like me.
Regards,
Patrick Briggs,
Pasadena, CA

I have written this query to return only numeric characters from a string.
select *
from TableA
where isNumeric(Column_A) = 1
But I have discovered that the following
SELECT IsNumeric('-')
SELECT IsNumeric('£')
SELECT IsNumeric('$')
SELECT IsNumeric('+')
all return a value of 1. I do not want these in my result set.
If I use Column_A NOT LIKE '%[a-z]%' and Column_A <> '' I get characters such as "", ----- etc in my result set.
I would like a simple way of only returning numbers in my resultset.
Thanks for looking at this.

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 want to strip off the last three characters from an item number. The only thing is tht every item number is not the same lenght. The last three characters of this number are packing codes that I do not need. Fore example I can have all these numbers:
EFJ50701033
EFW1546066
RFM4925156
70561033
89541899
How would I remove the last three characters and only remain with whatever is in front of those three characters?
Any help is greatly appreciated!

I'm using sys.dm_fts_parser dynamic management function to tokenize a string of characters >4000. The function doesn't accept a query_string parameter >4000 characters. Is there a way around this? I've tried to execute the SELECT defined in the function but that doesn't work. Â

I am unfamiliar with the built-in functions in SQL Server. I would like to display a numeric
field with leading zeros. In oracle the sql stmt would be:
SELECT TO_CHAR(amt,'000000')
FROM table_x;
Thus, the number 35 would be returned as 000035.
Is there a way to do this in SQL Server?
Thanks.

I want to write a query which splits numeric characters which appear in the end of the string.
if the sting is like 'Langabaa straat 23' Then the result must give ''Langabaa straat' and '23'
if the string is like 'Jacob straat 23 avenue' The the result must give 'Jacob straat 23 avenue' and ' '
if the string is like 'Jacob avenue, 43' The result must give me 'Jacob avenue' and '43'
So you see that there is comma and a space that does the separation.. how can i achieve this in a query???

I'm attempting to move data from a text field to a numeric field, but I need to be able to remove any non-numeric characters in that field first, but I do not want to lose the numeric data.
In the code below, the Value table is the table that will be converted.
INSERT INTO IntegerValues (FK_ReferenceID,FK_ReferenceType,FK_FieldID,FieldProperty,Value,CreationDate,CreatedBy,Revision)
SELECT FK_ReferenceID,FK_ReferenceType,FK_FieldID,FieldProperty,Value,CreationDate,CreatedBy,Revision
FROM StringValues WHERE FK_FieldID in (select id from ##tmpFields)
Any ideas on how I may do that?

I have a string 'ACDIPFJZ'
In my table one of the column has data like
PFAG
ABCDEFHJMPUYZ
KML

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)

Hi all,
I defined an user string type varible in the package as AccountLen. I am trying to use this varible in the Expression of Derived Column transformation.
I want to retrieve a part of column, i.e: Right(Column1, @AccountLen), this is always wrong because the AccountLen is string type. How I can convert it to the numeric so that can be used in the RIGHT function?
Thanks

This statement works fine in T-SQL, but when executed thru ODBC results in a <NULL>. How can I get this to work thru ODBC....? Im guessing I need to use CAST, but not sure how the sytax would be, my attempts have worked but still resulted in a <NULL>...
UPDATE mytable SET
switch = left(switch, 3) + '1' + right(switch , len(switch) -4)
WHERE blah = blah
(switch is a Numeric field)
Thanks,Adrian

Hi All,
I want to extract a numeric value from a string. Example, in a string like - Mgmt Pack: Processor Exception Threshold >80% Every 10 Minutes. - I want to extract that number 80. Since, later I'll want this number to plot a graph.
Since this is going to be an alert pulled from OnePoint (MOM Operational Database), the number will vary, and so I cannot look for the same number. So, can anyone help me how to get this working?
Thanks a lot in advance and let me know if the question is not clear.
Manoj Deshpande.

Hi All,
i'm using a "data conversion" object to convert a numeric field to a string just before i save the record set to the database.
the problem is when this numeric field is > 0 it looses the precision on its decimal value.
example, if numeric value is 0.32
after converting this to a string, the new value will be : .32
it's lost the 0 infront of it. i can't do this converion in the query level because it's a derived field, so i need to convert it to a string before stroing it.
when converting to string i'm using the code page 1252 (ANSI - Latin I). i also tried with unicode string both looses this 0 infront.
can any one help on this?
