If it's a Y/N flag (boolean) that needs to be indexed then you can just make it Y/NULL and handle it via code. This can substantially reduce the size of the index. (not talking about bitmap indexes now)

Are you planning to use the flagged column as a boolean across a jdbc connection? If so, then go with a number datatype. The 9i jdbc driver does not know how to handle boolean datatype, thus if you store 'Y' in a char column the jdbc driver will throw errors when the java application calls GetBoolean against the jdbc driver.

Would you use a number or char for a flag in a table? Would you use a char since it's one byte and a number is 22 bytes?
