sql - Set Values in column B based on values in Column A in SQL2005? -

-

i'm trying take existing column , parse each row words in string, i.e. sheet, page, card, , based on word (only 1 instance of 1 of these words in row) populate new column in same table value. if did not find of words, leave column b blank.

i.e. column contains word "sheet", populate column b letter "s"

so table like:

column  column b sheet        s page         p card         c

any appreciated!

update yourtable     set columnb = case when columna '%sheet%' 's'                        when columna '%page%' 'p'                        when columna '%card%' 'c'                        else null /* or '' if prefer */                   end
