The above accepted answer will fail if the data has a number after the # like '9201#CC1CC'

the REPLACE probably isn't the best approach here since it looks at the entire string replacing things.

Also depending on the amount of data you have, the regexp commands are an expensive function call to make.

Here is an updated regexp that will work for everything before the #
regexp_substr(mycol, '[^#]*')

One that returns everthing fromthestart of the column until a non-number:
regexp_substr(mycol, '^[0-9]*')

The substr/instr that will likely be faster than the regexp calls:
substr(mycol, 1, instr(mycol,'#')-1)
