Oracleで無効な識別子エラー。

Question

私はこのクエリをSQLサーバで実行していますが、正常に動作していますが、Oracleで実行しようとすると、無効な識別子 "IS NULL"というエラーが生成されます。誰でもOracleのサポートされているクエリでこのクエリを翻訳できますか？私を助けてください。

     RM_LIVE.EMPNAME.LASTNAME, RM_LIVE.CRWBASE.BASE ,RM_LIVE.CRWCAT.crwcat AS "Rank",

isNULLは、Oracleで定義されていないありがとう、あなたがそれらの文字列リテラルの代わりに、実際の数字作り、単一引用符で囲まれた数字を持っていないのはなぜNVL代わり
