Return Only Numeric Characters From A String Column

Dec 4, 2007

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.

Pattern Matching - Searching For Numeric Or Alpha Or Alpha-Numeric Characters In A String

Aug 18, 2006

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

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?

SQL Server 2012 :: Strip Non-numeric Characters From A String

Jul 15, 2015

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....

Using Stuff To Return A String Of Values From A Column Without A Cursor

Dec 13, 2007

I think it was Pat Phelan who posted a little trick here where he used the STUFF function to create a string fo values from a column without using a cursor.

I am starting a brand new project and I did my table design and I am awaiting a finalized requirements document to start coding and I thought I would spend a little time writing some code to autogenerate some generic one record at a time SELECT, INSERT,UPDATE and DELETE stored procedures. With the coming holiday things are getting quiet around here.

The code that is not working is listed below. It does not work. It returns Null. I suck.

DECLARE @column_names varchar(8000)

SET @column_names = ''

SELECT @column_names = STUFF(@column_names,LEN(@column_names),0,C.COLUMN_ NAME + ', ')
FROM INFORMATION_SCHEMA.COLUMNS C
WHERE TABLE_NAME = 'MyTable'

SELECT @column_names

little help?

Converting Numeric To Characters

Sep 29, 2000

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.

Split Numeric Characters From The End.

Jun 29, 2007

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???

0.99

How Can I do this in my select?
