整数を文字列として解釈する

Question

このコードではCSVにテーブルSQLを出力しましたが、これはうまくいきますが、私は2つの異なる値、例えば'0'の2つの異なる値を表すために整数を使用しています。 column Aに'All'と、はに'New'と表示されます。私は0を2つの異なるものとして解釈する方法を考え出すのに問題があります。すべての値に対して'0 = X'と言うことはできません。任意の洞察力をいただければ幸いです：あなたのSQL文で

は、それらの列のために次の操作を行います

SELECT IF(column_name_A = 0, 'All', column_name_A) FROM your_table 

SELECT IF(column_name_B = 0, 'New', column_name_B) FROM your_table
