Question

我有給我一定的查詢問題，我不知道如何解決這個問題..這裏是查詢..

，我有這樣的錯誤：

Incorrect syntax near ':'.

請幫助我不擅長這個:(

Answer 1

的:as_studid和:as_period事情13759某些客戶端軟件，該查詢的最有可能的參數。在實際執行查詢之前，:name位被@P1或@as_studid替換（通常由一些中間層軟件），所以服務器從不會在那裏看到冒號（並且從不抱怨）。

如果您不是客戶端軟件開發人員，並且被簡單地分配了執行查詢任務的任務，那麼您需要手動應用上述轉換。我建議你聲明變量@as_studid和@as_period並分別用它們代替:as_studid和:as_period。另外，您可能需要爲它們分配一些值，以便在運行查詢時可以看到一些結果。下面是修改後的腳本如何可能看起來像一個例子：

DECLARE 
    @as_studid int, 
    @as_period int; /* those are just my guesses, the actual types 
         might need to be something other than int */ 

SET @as_studid = 10; 
SET @as_period = 20; /* again, those are arbitrary values off the top 
         of my head but you might have to discover some 
         real ones before going on */ 

SELECT dcm.code DCM_No, 
     dcm.datetime_created DCM_Date, 
     lne.seq_number, 
     par.code, 
     par.description particular, 
     ft.description fee_type, 
    lne.amount, 
     case when lne.drcr =1 then 'Debit' else 'Credit' end DrCr, 

     case when isnull(dcm.is_sd,'N') = 'Y' then 'Salary Deduction' else null end is_sd, 
     org.description Company, 
     org.postal_address company_addr, 
     'S.Y. ' + substring(sy.school_year,1,4)+'-'+substring(sy.school_year,5,4) +' '+sem.description SY, 
     entity_a.code + ' - ' + coalesce(entity_a.stud_lname,'') +', '+coalesce(entity_a.stud_fname,'') +' '+coalesce(entity_a.stud_mname,'') Student, 

    case when isnull(dm.description2,'') = '' then 
      crs.course_short_name + '-'+convert(char(1),entity_a.stud_grade) 
     else crs2.course_short_name + '-'+convert(char(1),reg.stud_grade) end as Course, 
     isnull(dm.description2,'Not Enrolled') 

    FROM es.lib_rgn_students entity_a 
     left join ars.ars_dcm dcm on dcm.entity_id = entity_a.id 
     LEFT JOIN afs.entity entity_b ON dcm.prepared_by_id = entity_b.id 
     LEFT JOIN ua.user_account ON dcm.prepared_by_id = ua.user_account.id 
     left join ars.ars_dcm_line lne on lne.ars_dcm_id = dcm.id 
     left join es.lib_fin_fees_master par on par.id = lne.ars_particular_id 
     left join es.lib_fin_feetype ft on ft.code = lne.fee_code 
     left join es.stp_sysem sy on sy.id = dcm.period_id 
     inner join es.stp_semesterms sem on sem.code = sy.semester and sem.trimester = 0 
     inner join afs.organization org on org.id = sy.company_id 
     inner join es.lib_crs crs on crs.id = entity_a.course_id 
     left join es.trn_rgn_reg_hdr reg on reg.period = sy.id and reg.stud_id = :as_studid 
     left join document_status_map dm on dm.code = reg.document_status 
     left join es.lib_crs crs2 on crs2.id = reg.course_id 

WHERE 
     (dcm.entity_id = @as_studid) AND -- the vars declared above are used 
     (dcm.period_id = @as_period) AND -- here instead of the ':'-bits 
     (dcm.document_status_code not in(2,3)) 

或者，也可以不變量來做到，只需更換:as_studid和:as_period用一些真實值。但是這樣你就不得不記住原始查詢中參數化了什麼，無論如何，如果你的任務是修改查詢本身，你可能必須提交它與: -names，就像你一樣收到了。

Answer 2

如果您列確實被稱爲：as_studid然後用方括號括起來。 e.g.:-

WHERE 
     (dcm.entity_id = [:as_studid]) AND 
     (dcm.period_id = [:as_period]) AND 
     (dcm.document_status_code not in(2,3))  

這應該解決這個問題
