Sql 与2个临时表联接

如何在下面的查询中再创建一个临时表，以便与相同的表联接

WITH financial_move_out_due_days AS ( 
    SELECT property_id, 
        management_company_id, 
        value 
    FROM property_preferences 
    WHERE property_id IN ( 112,332 ) AND management_company_id = 23 
    )
    SELECT 
        l.id,
        l.primary_customer_id,
        ( c.name_first || c.name_last ) AS customer_name_full,
        c.email_address AS customer_email_address,
        c.phone_number AS phone_number
    FROM leases l
    JOIN customers c ON ( c.management_company_id = l.management_company_id AND c.id = l.primary_customer_id )
    JOIN financial_move_out_due_days fmpodd ON ( fmpodd.management_company_id = l.management_company_id AND fmpodd.property_id = l.property_id )
    WHERE
        l.management_company_id = 23
        AND l.property_unit_id IS NOT NULL
        AND l.unit_space_id IS NOT NULL';

试着这样做：

   WITH financial_move_out_due_days AS 
    ( 
        SELECT property_id, 
            management_company_id, 
            value 
        FROM property_preferences 
        WHERE property_id IN ( 112,332 ) AND management_company_id = 23 
    ),
    another_financial_move_out_due_days AS 
    ( 
        SELECT property_id, 
            management_company_id, 
            value 
        FROM property_preferences 
        WHERE property_id IN ( 112,332 ) AND management_company_id = 23 
    )
    SELECT 
        l.id,
        l.primary_customer_id,
        ( c.name_first || c.name_last ) AS customer_name_full,
        c.email_address AS customer_email_address,
        c.phone_number AS phone_number
    FROM leases l
    JOIN customers c ON ( c.management_company_id = l.management_company_id AND c.id = l.primary_customer_id )
    JOIN financial_move_out_due_days fmpodd ON ( fmpodd.management_company_id = l.management_company_id AND fmpodd.property_id = l.property_id )
    JOIN another_financial_move_out_due_days fmpodd ON ( fmpodd.management_company_id = l.management_company_id AND fmpodd.property_id = l.property_id )
    WHERE
        l.management_company_id = 23
        AND l.property_unit_id IS NOT NULL
        AND l.unit_space_id IS NOT NULL';

我相信你的意思可能是CTE，而不是临时桌子。CTE更像是一个视图，而不是一个临时表，老实说，它通常是不必要的，但只是语法上的糖分——它更容易阅读，但它通常不会做任何你可以用更复杂的sql做的事情——只是将复杂的sql分解成碎片@realnumber3012已经回答了您的问题。如果你需要更多的细节，请告诉他或我。我不知道CTE，因为我是PGSQL新手。要使用相同的

连接，只需使用一个CTE两次即可。请澄清您的问题。我从@realmumber3012和ramesh获得了解决方案。我相信您的意思可能是CTE，而不是临时表。CTE更像是一个视图，而不是一个临时表，老实说，它通常是不必要的，但只是语法上的糖分——它更容易阅读，但它通常不会做任何你可以用更复杂的sql做的事情——只是将复杂的sql分解成碎片@realnumber3012已经回答了您的问题。如果你需要更多的细节，请告诉他或我。我不知道CTE，因为我是PGSQL新手。要使用相同的
