How to find all upper case strings in a MySQL table?

Question

I initially thought this is trivial. Then thought \'binary\' might do it. I am unsure at this point.

Name
----
John
MARY
Kin
TED

I would like t

You just use the UPPER() function on the Name field and compare the results with the original value of Name:

select Name from Table where Name = UPPER(Name)

This way

UPPER(Name)   ||  Name
---------------------------------------
JOHN          !=  John
MARY          ==  MARY
KIN           !=  Kin
TED           ==  TED

only the rows you need will be returned.

As @mdoyle commented here, you should define the column with the right collation (case sensitive), otherwise as others did answer you need the BINARY operator to compare case insensitive columns.
