與輸入參數查詢XML

Question

目前我使用此查詢，得到的結果：

Select * 
From Staff 
Where StaInsurance.exist('/COLInsuranceCompany/DOInsuranceCompany[Name/text()[. = "Apollo Life Assurance"]]') = 1 

我怎樣才能在查詢中使用的輸入參數，而不是硬編碼字符串，下面沒有工作：

declare @IInsurance nvarchar(200) 
set @IInsurance = 'Apollo Life Assurance' 

Select * 
From Staff 
Where StaInsurance.exist('(/COLInsuranceCompany/DOInsuranceCompany/Name[id=(sql:variable("@IInsurance"))])[1]') = 1 

Answer 1

declare @IInsurance nvarchar(200) 
set @IInsurance = 'Apollo Life Assurance' 

Select * 
From Staff 
Where StaInsurance.exist('/COLInsuranceCompany/DOInsuranceCompany/Name[text() = sql:variable("@IInsurance")]') = 1
