解释整数作为字符串CSV

我发现这个代码输出SQL表到CSV，从我们使用整数在两个不同的列代表两种不同的价值观，工作正常，但在表中，我拉，例如，'0'应在column A和'0'中应被读作'All'，在Column B中应被读作'New'。我无法弄清楚如何将0解释为两个不同的东西，因为我不能只对所有的值说'0 = X'。任何有识之士将不胜感激：解释整数作为字符串CSV

在SQL语句中做这些列如下：

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
