Question

我有这个Oracle查询：

   SELECT company, structure_id, team_code 
   FROM structure_main_tab 
   WHERE (company, parent_structure_id, team_code) 
   IN (SELECT company, structure_id, team_code 
      FROM structure_main_tab 
      WHERE (company, parent_structure_id, team_code) 
      IN (SELECT company, structure_id, team_code 
          FROM company_user_tab 
          WHERE UPPER(fusername) = UPPER('xxx') AND fdeleted = 'N'
          )
   );

我正在尝试将此oracle查询转换为SQL Server查询。

有人可以帮我吗？

Answer 1

尝试以下查询：

     SELECT company, structure_id, team_code into #temp1 
      FROM company_user_tab 
      WHERE UPPER(fusername) = UPPER('xxx') AND fdeleted = 'N'





      SELECT company, structure_id, team_code
      FROM structure_main_tab Mt inner join #temp1 tt 
      on Mt.company=tt.company and mt.parent_structure_id=tt.structure_id
      and mt.team_code=tt.team_code

认为您不能在Sql Server中为IN子句使用多个列。

我会用exists子句和连接替换

SELECT company, structure_id, team_code 
   FROM structure_main_tab  smt
   WHERE EXISTS (select null from 
                 structure_main_tab smt1
                 join company_user_tab cut on cut.company = smt1.company and 
                                              cut.structure_id = smt1.parent_structure_id and
                                              cut.team_code = smt1.team_code
                where UPPER(cut.fusername) = UPPER('xxx') AND cut.fdeleted = 'N'  
                and smt.company = smt1.company 
                and smt.parent_structure_id = smt1.structure_id
                and smt.team_code = smt1.team_code)

如何在where子句中使用多个参数将Oracle转换为MS SQL？
