i have a table named transport, which has 5 stoppage columns, namely, stoppage1,stoppage2,stoppage3,stoppage4,stoppage5

I need to get distinct values among all rows and columns.

Here is what i did :


This returns me

STOPS

According to requirement, i need the following output (only distinct values regardless of case) :

STOPS
A/a (any of two)

Use the UPPER function to convert all values to uppercase.

You're welcome.

It is up to you to decide which records should be considered identical and which different. INITCAP does something different than UPPER, but if INITCAP meets your criteria, so be it. Using INITCAP to define uniqueness seems a bit strange to me, though (you're disregarding only the case of letters at the beginning of words, that looks quite arbitrary to me).
 
It is sorta covered in the JavaRanch Style Guide.
