A simplified example follows: with data1 ( ID_1 ) as ( Select ID from ID_TABLE where ID > 10 ) , cmedb.data2 ( MIN_ORIGINAL_ID ,OTHER_ID ) as

问题 We have legacy table where one of the columns part of composite key was manually filled with values: code ------ '001' '002' '099' etc. Now, we have feature request in which we must know MAX(code) in order to give user next possible value, in example case form above next value is '100'. We tried to experiment with this but we still can't find any reasonable explanation how DB2 engine calculates that MAX('001', '099', '576') is '576' MAX('099', '99', 'www') is '99' and so on. Any help or
