Hi All,
Can anyone of you send me a query to fetch only the name of the users who has name in mixed case (lower and upper case) .
And query to fetch only name with upper case ?
Thanks.

Can you post the query that you are working on.

Hi,
I hv not tried that one .....as i am not familiar with that .
Can u help.
select * from tablename where regexp_like(nam e,'[A-Z]'); - I executed this query and got
ERROR at line 1:ORA-00920: invalid relational operator
[IMG]Hello[/IMG]
Found the query:
select name from tablename where name != lower(name);
Hope this will help others
For Mixed Case and Upper Case fetch -
-
select * from emp where
-
LENGTH(REPLACE(TRANSLATE(name,'abcdefghijklmnopqrstuvwxyz',' '),' ','')) > 0

wouldn't it be easier to use - select * from emp
-
where name != lower(name) --Only this line in case of mixed cases and upper cases
-
and name != upper(name) --add this line just to get mixed cases
-
Its always better not to use != (inequality) sign with strings
My solution that includes TRANSLATE,REPLA CE can be easily rewritten using Regular Expressions in 10g. I am using 9i in my office so provided that solution
Well, in this case, the inequality is the lesser evil. The translate and replace will have to go through each string from the start to the end, even if there are no occurances of the occurance to replace or translate. Using a combination of translate and replace will make the query a lot slower. The inequality will stop with the comparison as soon as it finds the first difference.
Pilgrim.
Its not becuase of performance that I am asking not to use inequality, its because it causes wrong results some times in real time scenarios

Before I embark on a new long-term project I'd appreciate your advice on how to split up

Hello,
I'm stumbled at a serious problem, and quite frankly getting

straight to the point.
I have this Python program, that performs MySQL queries to a database.
These queries are performed at regular intervals. Basically it is
looking for fields that match certain criterias. Such fields are not
present at all time. When the program finds such field, it then takes

Looking for suggestions on how to handle bad words that might
get passed in through $_GET variables.
My first thoughts included using str_replace() to strip out such
content, but then one ends up looking for characters that wrap
around the stripped characters and it ends up as a recursive
ordeal that fails to identify a poorly constructed $_GET
variable (when someone hand-types the item into the line and
makes a simple typing error).

Hi;
I am transferring data from MySql to db2 using my own java/jdbc program.
Working out ok, except for the fact that our apps use mixed-case names for
tables and columns. Although my CREATE TABLE commands issued via jdbc uses
mixed case for the names, db2 insists on using only upper case. (This also
happens from the CLP or DB2CC, but my concern is for it to work via
jdbc.)
Is there a simple setting at the database level to allow mixed...

I have a table where a few of the users entered vendor names ALL IN

What to I have to do to have the user change the name, but keep the

change the existing record.
The form is simple - Choose the vendor from the drop-down list.
