Question

我有许多使用CTE，临时表，表变量和子查询的存储过程，我需要获取存储过程中使用的所有列（包括数据库，模式和表/视图）的列表。我不需要获取临时表，表变量或CTE中的列。我只需要在我的服务器上的数据库中的表或视图中定义的引用列。

我尝试了sys.dm_sql_referenced_entities和sys.sql_expression_dependencies，但他们没有在第一个选择查询后返回列或在CTE中选择。

这是我用来获取存储过程中使用的所有表但不返回列的内容。

    declare
        @target_table as varchar(255) = N'my_sp',
        @target_schema as varchar(255) = N'dbo';

    select distinct od.name as depname
        ,1 as depnumber
        ,od.type as deptype
        ,sd.name as depschemaname
    from sys.objects as o
    inner join sys.schemas as s
        on s.schema_id = o.schema_id
    inner join sys.objects as od
        on od.object_id = o.parent_object_id
    inner join sys.schemas as sd
        on sd.schema_id = od.schema_id
    where s.name = @target_schema
        and o.name = @target_table and od.type = 'U'

    union

    select distinct od.name as depname
        ,case 
            when od.type = 'P'
                then np.procedure_number
            else 1
            end as depnumber
        ,od.type as deptype
        ,sd.name as depschemaname
    from sys.sql_expression_dependencies d
    inner join sys.objects o
        on o.object_id = d.referencing_id
    inner join sys.schemas s
        on s.schema_id = o.schema_id
    inner join sys.objects od
        on od.object_id = d.referenced_id
    inner join sys.schemas sd
        on sd.schema_id = od.schema_id
    left join sys.numbered_procedures np
        on np.object_id = d.referenced_id
    where s.name = @target_schema
        and o.name = @target_table and od.type = 'U';

如何获取存储过程中引用的所有列的列表？
