By default bash doesn't check it's window size after every command. The good thing is that you can make it. Add "shopt -s checkwinsize" to your ~/.bashrc or /etc/profile. Works like a charm. To reproduce the "error": man bash resize the window quit, and type a long string at the prompt. It will wrap at the window's original width and wrap onto the same line. echo "shopt -s checkwinsize" >> ~/.bashrc (or /etc/profile) source ~/.bashrc try again It works correctly! In my opinion this is something (along with a decent PS1) that should be added to the default /etc/profile or /etc/skel/.bashrc and the user should never have to set by themselves. -- Thanks, Thomas Achtemichuk
Gegeben sei ein Tabelle t, die Doubletten in der Spalte s hat. Außerdem hat die Tabelle noch einen Primary Key in der Spalte id.
Folgender Code findet die Doubletten:
SELECT t1.s, t2.s FROM t AS t1, t as t2 WHERE ( (t1.s=t2.s) AND (t1.id < t2.id) );
Würde “t1.id<>t2.id” stehen, würden alle Doubletten zweimal auftauchen. Sollen Doubletten aus zwei verschiedenen Tabellen abgeglichen werden, hat man diese Probleme natürlich nicht.
