Hi All,
We have a table say TableA. It has a column 'Detail' which is varchar(250). I has some values with '.' in end and some without '.' Example (Row 1 : 'ADB', Row2 : 'ADC. DCD.' Row3 : 'ADC.')
We need to remove the '.' which is occurring only in the last of 'Detail' column and load it. Example after removing '.' (Row 1: 'ADB', Row2 : 'ADC. DCD', Row3 : 'ADC')
Database is SQL Server 2008 R2 and we are inserting into the TableA using a INSERT INTO 'SELECT' query..
Please suggest.
Thanks
Jim

DECLARE @myRow VARCHAR(10) = 'ADC. DCD.';

SELECT ISNULL(REVERSE(STUFF(REVERSE(@myRow),CHARINDEX('.',REVERSE(@myRow),1),1,'')),@myRow);

Thanks Koen!! This is perfect. But now there is a small change, there should not be any special character at the end. Could you please suggest..

Maybe something like this would help.

WITH SampleData(String) AS(

SELECT 'ADB' UNION ALL SELECT 'ADC. DCD.' UNION ALL SELECT 'ADC.'

)

SELECT CASE WHEN RIGHT( String, 1) LIKE '[^A-Za-z0-9]'

THEN LEFT( String, LEN( String) - 1)

ELSE String END

FROM SampleData

Do you have more than one special character at the end? Could you give some sample data?

Hi Luis,

I think this is not working properly when the column is ending with space ' '.

Sample data

'ABC DS.'

'AD.'

'DG@'

'DGC DS '

'fdsf fs/'

'fs fds //'

Here's a modification.

WITH SampleData(String) AS(

SELECT 'ADB' UNION ALL SELECT

'ADC. DCD.' UNION ALL SELECT

'ADC.' UNION ALL SELECT

'ABC DS.' UNION ALL SELECT

'AD.' UNION ALL SELECT

'DG@' UNION ALL SELECT

'DGC DS ' UNION ALL SELECT

'fdsf fs/' UNION ALL SELECT

'fs fds //'

)

SELECT CASE WHEN RIGHT( RTRIM(String), 1) LIKE '[^A-Za-z0-9]'

THEN LEFT( String, LEN( String) - PATINDEX('%[A-Za-z0-9]%', REVERSE(String)) + 1)

ELSE String END

FROM SampleData

If the requirement is to remove trailing spaces and all trailing non-alpha-numerics Luis code is what's needed; but it seems a bit heavyweight if the requirement is just to eliminate trailing spaces and at most one '.'. If the requirement is just spaces and at most one '.' this simpler code will do instead:

FROM SampleData;

WITH SampleData(String) AS(

SELECT 'ADB' UNION ALL SELECT

'ADC. DCD.' UNION ALL SELECT

'ADC.' UNION ALL SELECT

'ABC DS.' UNION ALL SELECT

'AD.' UNION ALL SELECT

'DG@' UNION ALL SELECT

'DGC DS ' UNION ALL SELECT

'fdsf fs/' UNION ALL SELECT

'fs fds //'

)select CASE WHEN right( rtrim(String), 1) ='.'

THEN rtrim(substring(String,1,len(String)-1))

ELSE rtrim(String) END as NewString

FROM SampleData;
