请在下面找到查询：

SELECT a.reco_index_content_code,a.reco_index_content_name, a.reco_index_user_action_download_file, 
        CASE WHEN b.refdata_profession_passion_code LIKE '%-%'
                 THEN 'passion'
                 ELSE 'profession' 
             END AS passion_or_profession
FROM tbl_reco_index_contents a 
INNER JOIN tbl_reference_databases b
ON a.reco_index_content_code = b.refdata_content_code
WHERE a.reco_index_user_action_installed = 1 and a.user_profile_number =  1

查询返回重复的某些行。如果查询不是自我解释的，我将不得不回复更多细节。

任何帮助深表感谢

根据您显示的结果，一个简单的DISTINCT将删除重复项，因为列中的所有值在两行中都相同，

SELECT DISTINCT .....
