SQL NOT IN子句不工作

有人知道这个SQL代码的问题在哪里吗？在与UNION的查询中，我在FROM行的周围不断得到红色下划线。如果你能告诉我如何防止代码重复，那就更好了

DECLARE @collection_site_address_id INT;
SET @collection_site_address_id =

    WHERE 
        sample_specimen_id = @sample_identifyingnumber
        AND client_address.addresstypeid = 1

    NOT IN (

答复: 经过一点调查，这似乎是一种更有效的方法。您可以使用IN或NOT IN子句将一个表结果集与另一个表结果集进行比较。或者，可以使用EXISTS或NOT EXISTS子句将标量aka变量与表结果集进行比较

[标量]存在[表/结果集] [标量]不为NULL且不存在[表/结果集]

DECLARE @collection_site_address_id INT;
SET @collection_site_address_id =

    SELECT TOP 1

        dbo.ws_test_request
        INNER JOIN client ON ws_test_request.collection_site_id = client.identifyingnumber
        INNER JOIN client_address ON client.clientid = client_address.clientid
    WHERE 
        sample_specimen_id = @sample_identifyingnumber
        AND client_address.addresstypeid = 1
)

IF      
    @collection_site_address_id IS NOT NULL AND NOT EXISTS
    (
        SELECT 
            [address].addressid
        FROM  
            [address]
            JOIN (
                SELECT 
                    client_address.addressid,

                    LEFT OUTER JOIN client ON relatives.clientid = dbo.client.clientid

                UNION

                SELECT

[表格/结果集]中的[表格/结果集] [表格/结果集]不在[表格/结果集]中
