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

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

Answer 3

使用CASE声明：

case BASIC when 'True' then 'Yes' ELSE 'No' end

Answer 4

像这样：

SELECT TipoImovel_Id AS TII_SEQ, Descricao AS TII_DSC, Sigla AS TII_DSC_SIGLA, case when basic = 'FALSE' then 'NO' else 'YES' end 
FROM San_TipoImovel

Answer 5

你可以创建一个用户定义的函数，以便将来你可以说：

select dbo.YesNo(Active) from APAccount

这是函数

CREATE FUNCTION [dbo].YesNo(@Value Bit)
    RETURNS varchar(3)
    BEGIN
      DECLARE @R as varchar(3)

      SET @R =
        (
        Select 
            case 
                when @Value = 1 then 'Yes'
                else 'No'
            end
        )
       RETURN @R
    END

TSQL返回NO或YES而不是TRUE或FALSE
