$foo is definitely my favorite, with $bar and $baz coming next.. I am a bit suprised, though, that no one mentionned $i (and its companions, $j and $k, when needed). In French, the most common equivalent is $toto, and, when additional alternates are needed, they may usually be $tata, $tutu and $titi.
As it so happens, i added the following comment to a VIEW just this morning:
-- This causes a problem as ROLLUP adds a record even if it already ex
+ists in the data. For example:
-- WITH A AS (SELECT NULL A FROM Dual), B AS (SELECT A FROM A GROUP B
+Y ROLLUP(A)) SELECT Rownum, A FROM B
Although in test-code and designs that are designed to be thrown away, i usually use $mist, $kraffel, und $dreck from my local austrian dialect for garbage. Just as a reminder for myself that the code should neither be released to the public nor used in production. (function names often follow a similar pattern, but their mentioning in PM would probably get me banned).
"For me, programming in Perl is like my cooking. The result may not always taste nice, but it's quick, painless and it get's food on the table."
Although poorly written, this code can be explained as: If the the variable or the other variable from the first inside or, or the inside variable inside the other side of the outside or, or the other or inside the other side of the outside or equal their respective numbers, the code sets something else, entirely.
However, we can take a different approach with other and thore: If the the or the other other, or the thore's other inside or the other or equal their respective numbers, the code sets something else, entirely.
