Question

我无法让我的值在表变量中显示为空白而不是0.00。

表格设置/声明。

        DECLARE @PolicyCoverages TABLE (
        CoverageType varchar(100),
        ScheduleLimit money,
        BlanketLimit money,
        Deductible money,
        Premium money
    )

    INSERT INTO @PolicyCoverages (CoverageType, ScheduleLimit, BlanketLimit, Deductible, Premium)    
    SELECT  'Words for a description',
            '10000.00', 
            '0.00', 
            '2500.00', 
            '142.50'

一旦所有数据到位（有许多选择引入数据）我想提取具体信息，如下所示。

SELECT CoverageType,
       CASE WHEN ScheduleLimit < 0 THEN '' ELSE ScheduleLimit END AS ScheduleLimit,
       CASE BlanketLimit WHEN '0.00' THEN '' ELSE BlanketLimit END AS BlanketLimit,
       Deductible, 
       Premium 
    FROM @PolicyCoverages
    WHERE (ScheduleLimit > '0.00') OR (BlanketLimit > '0.00')

我不想显示0.00我想要一个空格＆＃39;＆＃39;。我尝试过皈依者，我尝试过施法，并且两次尝试时都显示出来。

WHEN CAST(ScheduleLimit as varchar(10)) < 0 THEN ''
WHEN Schedulelilmit < 0 THEN CONVERT(varchar(10), '')

无论我尝试哪种方式，它都会以0.00

结束

Answer 1

使用SPACE（n）函数获取空格键。 'n'是一个整数

Answer 2

如果你想要＆＃39;＆＃39;这是角色，你需要将你的钱兑换成varchar：

SELECT CoverageType,
       CASE WHEN ScheduleLimit < 0 THEN '' ELSE cast(ScheduleLimit as varchar(30)) END AS ScheduleLimit,
       CASE BlanketLimit WHEN 0 THEN '' ELSE cast(BlanketLimit as varchar(30)) END AS BlanketLimit,
       Deductible, 
       Premium 
    FROM @PolicyCoverages
    WHERE (ScheduleLimit > '0.00') OR (BlanketLimit > '0.00')

如果您不希望money成为varchar，则应使用NULL代替＆＃39;＆＃39;

您无法在同一列中显示money和char，因此您无其他选择：或者您将所有列转换为varchar，或保留money但请使用NULL代替＆＃39;＆＃39;。

Sean Lange得到了它！显示NULL确实纠正了我的问题。前端（我无法控制）将NULL值显示为空白，因此将其设置为NULL会更正所有内容。

SELECT CoverageType,
       CASE ScheduleLimit WHEN 0 THEN NULL ELSE ScheduleLimit END AS ScheduleLimit,
       CASE BlanketLimit WHEN 0 THEN NULL ELSE BlanketLimit END AS BlanketLimit,
       Deductible, 
       Premium 
    FROM @PolicyCoverages
    WHERE (ScheduleLimit > 0) OR (BlanketLimit > 0)

SQL Server SELECT Money作为空白而不是0.00
