TSQL返回NO或YES而不是TRUE或FALSE

Question

如果某些列返回FALSE,如何显示不同的值,

例如,

COLUMN"BASIC"返回FALSE,但我需要为用户显示YES或NO.情况FALSE,返回NO.

Answer 1

如果是varchar或bit,则处理NULL

case
    when BASIC = 'FALSE' then 'NO'
    when BASIC <> 'FALSE' then 'YES'
    else 'UNDEFINED'
end

或者如果只是位

case
    when BASIC = 1 then 'YES'
    when BASIC = 0 then 'NO'
    else 'UNDEFINED'
end

编辑:

SELECT 
    TipoImovel_Id AS TII_SEQ,
    Descricao AS TII_DSC, 
    Sigla AS TII_DSC_SIGLA,
    -- choose which one you want from the answers here
    case
        when BASIC = 1 then 'YES'
        when BASIC = 0 then 'NO'
        else 'UNDEFINED'
    end AS SomeColumnName
FROM San_TipoImovel";

Answer 2

从 SQL 2012 开始，您可以使用 IIF 函数

IIF(BASIC = 'TRUE', 'YES', 'NO')

Answer 3

case when column = 'FALSE' then 'NO' else 'YES' end
