久しぶりにOracle PL/SQLをいじり中
なぜかSelect文でコンパイルエラー
SELECT A.Column1
FROM TableName AS A ← ここでエラー
悩むこと30分
SELECT A.Column1
FROM TableName A
でした
自分のあほさ加減に絶望した
ちなみにSQLServerでは
上の書き方でもOK

アホ……とは思わなかったりしますですよ。
OracleとSQLServer、まぁここにDB2が混じってきたとしても、大阪弁と関東弁と東北弁ぐらいに方言が違うし、ACCESSが入ってくるとさらに混乱の坩堝が待ってますし（＾＾；
標準SQLと方言SQLの違いって種類こなさないと見えてこないんですよね（遠い目）

SQLServerとAccessでも似たようなことやったりです。＾＾；
MｙSQLとかいろいろ使える語句が違うし、混乱しますよ。

ISAMをやっている私は、人間失格ですか？
って言った冗談はおいといて...
片桐さんもおっしゃっていますが、格DBのSQLの方言ですからね。
慣れていただくしかないですよね。
(Oracle10gってうまいのか？)

>片桐様
ありがとうございます。
DB2!!
一度は触ってみたいDBMSです。
忘れっぽい私は毎回方言違いで時間取られて困ってます＾＾；
>Zee様
ありがとうございます。
MySQLもありますねぇ。
これも触った事ないなぁ。
あとPostgreSQLもあるのか。
>HiJun
ありがとうございます。
ISAM!!!
聞いた事はありますが、実際見たことないです。
すごいです。
Oracle10gは今回初めて触ってますが、
DBAな方が、いろいろパラメーターが変わってて苦労されてます。
SQLServerの様に自動で管理するパラメーターが増えてきているとか。
各DBMSで使えるSQLの比較表とかあったら便利なのかな
作るとしたら逆引きっぽいのがいいかな？
