Sql 将两行格式化为一行

我试图将两行结果合并成一行。以下是我的结果：

| OwnerTaxRate | OwnerTaxAmount | OwnerTaxTotal | LoanTaxRate | LoanTaxAmount | LoanTaxTotal
|     8.4%     |     71.40      |     921.4     |    NULL     |     NULL      |    NULL
|     NULL     |     NULL       |     NULL      |    8.4%     |     10.08     |    130.08

以下是我需要返回结果的方式

| OwnerTaxRate | OwnerTaxAmount | OwnerTaxTotal | LoanTaxRate | LoanTaxAmount | LoanTaxTotal
|     8.4%     |     71.40      |     921.4     |    8.4%     |     10.08     |    130.08

它之所以要创建两行，是因为每个订单都有两个基于

LoanHolder

（0或1）的条目。我认为添加一个

CASE

语句来选择我想要拉取哪个LoanHolder是可行的，但显然不行。这是我的

SELECT

语句：

SELECT
    CASE 
        WHEN
            ORC.LoanHolder = 1 
            THEN  CONVERT(VARCHAR(MAX),ORC.Owner_TaxRateBasic) + '%'

基于您的loanHolder，使用另一个自身实例连接表

显示两行，但仅显示一个查询。如果你使用两个查询，你可以使用一个联合，但我不知道是否是这样。宾果！根据需要返回结果。非常感谢你在我白痴的时刻给予我的及时帮助！
