Question

我有以下查询，大约需要20-30秒才能生成结果。我想让结果时间缩短，我在前端使用访问来在后端创建查询和SQL Server。不确定是否有更简单的方法和更快的方式来运行此查询。

这是我的问题：

SELECT DISTINCT 
    [UB-04s].client_id, 
    DATEDIFF("yyyy", [UB-04s]![patient_dob], [UB-04s]![admit_date]) AS [AGE at Admission], 
    invalid_diag_codes_by_age.start_age_yrs, 
    invalid_diag_codes_by_age.end_age_yrs, 
    invalid_diag_codes_by_age.diag_code 
INTO 
    tmp10407
FROM 
    [UB-04s], invalid_diag_codes_by_age
WHERE 
    ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
    AND (([UB-04s].dx_Q)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
    AND (([UB-04s].dx_P)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_O)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_N)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_M)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_L)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_K)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_J)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_I)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_H)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_G)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_F)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_E)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_D)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_C)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_B)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].dx_A)=[invalid_diag_codes_by_age].[diag_code])) OR ((([UB-04s].client_id)=[Forms]![frmUB04s]![client_id]) 
   AND (([UB-04s].principal_dx)=[invalid_diag_codes_by_age].[diag_code]));

这些只是表格中的小部件，因为这些是大型表格......

来自表UB04s的字段：

client_id   principal_dx    dx_A    dx_B    dx_C    dx_D    dx_E    dx_F    dx_G    dx_H    dx_I    dx_J    dx_K    dx_L    dx_M    dx_N    dx_O    dx_P    dx_Q
527

116     2761    7802    4019    2724    V1582   2768                                                
117     55321

来自无效诊断代码的字段表：

diag_code   start_age_yrs   end_age_yrs age_range_desc  
04041           0               0.5         0-6 months of age       
27701           0                1          
3070           18                99         
99779           0                1          
5559           15                99

基本上我正在做的是搜索客户端的所有诊断代码，看看它是否是基于客户端年龄的无效诊断代码。

没有真正的细节可以使用，我完全猜测你想要什么。但是使用别名并删除所有额外的括号将有很大帮助。我也使用IN而不是重复的谓词。这不会完全像这样，但非常接近。

SELECT DISTINCT u.client_id
    , DateDiff(year, [UB-04s]![patient_dob], [UB-04s]![admit_date]) AS [AGE at Admission]
    , i.start_age_yrs
    , i.end_age_yrs
    , i.diag_code 
INTO tmp10407
FROM [UB-04s] u
cross join invalid_diag_codes_by_age i
WHERE u.client_id = [Forms]![frmUB04s]![client_id] 
AND 
(
    u.dx_Q = i.diag_code
) 
OR 
(
    u.principal_dx = i.diag_code
    AND
    i.diag_code in 
    (
        u.dx_P
        , u.dx_O
        , u.dx_N
        , u.dx_M
        , u.dx_L
        , u.dx_K
        , u.dx_J
        , u.dx_I
        , u.dx_H
        , u.dx_G
        , u.dx_F
        , u.dx_E
        , u.dx_D
        , u.dx_C
        , u.dx_B
        , u.dx_A
    )
)

为什么我的查询需要这么长时间来生成结果
