Find ONLY Capital Letters in word through IN SQL Server query

Question

I have to do this in SQL Server

I have data such as

Belo Horizonte , MG - Brazil
São Paulo , SP - Brazil
Barueri , SP - Brazil
Ferraz de Vasconcelos          


        

Answer 1

Collation matters. You need to add Collate to your query, such as:

Select * from table where exists (Select SUBSTRING(ADDRESS_BLOCK,PatIndex('% [A-Z][A-Z] %',ADDRESS_BLOCK),3) from table)
COLLATE Latin1_General_CS_AS_KS_WS ASC;

You may need a difference collation - your current one is clearly case insensitive. You can find you current collation, and replace Latin1_General_CS_AS_KS_WS with the one you need, replacing the CI with CS, to get the case senstive version of your current collation.

See: http://msdn.microsoft.com/en-us/library/ms184391.aspx

Answer 2

I think this will do it... or a variation thereof to suit your needs. In this case it'll pick out the first pair of of uppercase letters.

with dataset as 
(
    select 'Belo Horizonte , MG - Brazil' as val union all
    select 'São Paulo , SP - Brazil' as val union all 
    select 'Ferraz de Vasconcelos , SP - Brazil'  
)
select Substring(val ,PatIndex('%[A-Z][A-Z] %' COLLATE LATIN1_gENERAL_BIN,val),3)
from dataset

Answer 3

Could you just try this:

SUBSTRING([ADDRESS_BLOCK],PatIndex('%, [A-Z][A-Z] -%',[ADDRESS_BLOCK])+2,2)

Example

Answer 4

Select 2 leters after comma:

select substring(columnname, charindex(',', columnname) + 2, 2)
from tablename

or using -:

select substring(columnname, charindex('-', columnname) - 3, 2)
from tablename

---

Final, not elegant, solution:

SUBSTRING(ADDRESS_BLOCK,PatIndex('% [ABCDEFGHIJKLMOPQWXYZ][ABCDEFGHIJKLMOPQWXYZ] %',ADDRESS_BLOCK),3)

It selects two uppercase letters.

Answer 5

Try this: You need to both collate the column AND specify the capital letters. The regular expression [A-Z] is not case sensitive, even if you specify a collation sequence.

SELECT    SUBSTRING(
            ADDRESS_BLOCK
            , PatIndex(    
                N'% [ABCDEFGHIJKLMNOPQRSTUVWXYZ][ABCDEFGHIJKLMNOPQRSTUVWXYZ] %'
                , ADDRESS_BLOCK COLLATE sql_latin1_general_cp1_cs_as
                )
            , 3
            ) 
FROM 
    (
        SELECT 'Belo Horizonte , MG - Brazil' ADDRESS_BLOCK
        UNION
        SELECT 'São Paulo , SP - Brazil' 
        UNION
        SELECT 'Barueri , SP - Brazil' 
        UNION
        SELECT 'Ferraz de Vasconcelos , SP - Brazil' 
    ) n
