more than 4 upper case characters in a row

Experts,

For SQL Server 2012 -- if SQL Server version matters in this case.

I have a unique situation where I need to search a field to check for instance where there are more that 3 upper case characters in a row.

If the value in the column is MedicalRecordCD, I wouldn't want that.
If the value in the column is PatientPLNNumber, I would want that to be returned.

Any assistance is appreciated.

That was supposed to work, but obviously the sort order still gets in the way. If we just do Binary compare, it works:
SELECT DISTINCT ColumnNM
FROM ColumnBASE
WHERE  SourceSystemNM = 'PAYERSTAGE'
and COLUMNNM collate Latin1_General_BIN like '%[A-Z][A-Z][A-Z][A-Z]%'

There is no function within SQL to count uppercase letters.  You can create one using the below code.

You could then do WHERE dbo.CountUpperCase (PatientPLNNumber) > 4

CREATE FUNCTION CountUpperCase
(
    @input nvarchar(50)
)
RETURNS int
AS
BEGIN

    declare @len int
    declare @i int
    declare @count int
    declare @ascii int

    set @len = len(@input)
    set @i = 1
    set @count = 0

    while @i <= @len
    begin

        set @ascii = ascii(substring(@input, @i, 1))

        if @ascii >= 65 and @ascii <= 90
        begin
            set @count = @count +1
        end

        set @i = @i + 1

    end

    return @count

END

Like could be used, too:
... where field collate Latin1_General_CS_AS like '%[A-Z][A-Z][A-Z][A-Z]%'

Thank you for your assistance. Looking back at my post, I think I definatley could have been clearer...and I apologize.
This fn is close. It does give a count of all upper case characters within the field. I need it to return those where there are >= 4 Consecutive upper case characters

So 'MedicalRecordCD' would not be valid as the 4 ucase are not consecutive
PatientPLNNumber would be valid as it does have 4 consecutive ucase chars "PLNN"

Once again, I apologize for putting you down the wrong path.
I will see if I am able to modify this function to get it to return the desired output.

Thank you.

Did you try the LIKE approach? It should check exactly for that.

Hello, I did try a variation of both suggestions.


SELECT DISTINCT ColumnNM
FROM ColumnBASE
WHERE CountUpperCase(COLUMNNM) > 3
AND SourceSystemNM = 'PAYERSTAGE'
and COLUMNNM collate Latin1_General_CS_AS like '%[A-Z][A-Z][A-Z][A-Z]%'


SELECT DISTINCT ColumnNM
FROM ColumnBASE
WHERE  SourceSystemNM = 'PAYERSTAGE'
and COLUMNNM collate Latin1_General_CS_AS like '%[A-Z][A-Z][A-Z][A-Z]%'

I am still getting values back  such as   --> ActualCostAMT

...side note. I know this request may sound somewhat foolish. The background is we are implementing a new DW and there are strict naming conventions we have been asked to follow.
