Hi, using your code, how about left(:str, position('**' in :str)-1));
select left(:str, position('**' in :str)-1)) from yourtable However, to make
things easier for future users, think about changing the single '*' to e.g.
'-' and then you can keep your existing select statements and not have this
problem when a new ABC*DEFG********01 becomes ABC*DEFGHIJKLMN*01
