轉換轉換VARCHAR數據類型爲int，但沒有被定義爲int

Question

運行它時我做一個聯盟的所有超過2級不同分貝的我得到這個錯誤時失敗：

消息245，級別16，狀態1，第16行 將varchar值「12037.5」轉換爲數據類型int時轉換失敗。

但我的列沒有一個是整數類型？出於某種原因，它將Main選擇類型更改爲整數。

Answer 1

SPStr.WCode可能是一個varchar和102是int。嘗試在單引號中包裝102。

而且，如果所有這些類型的不是整數，工會將嘗試根據你的工會，這部分投他們作爲整數：

, 0 AS SPSTYPE 
, 0 AS SPSMODEL 
, 0 AS SPSSITE 
, 0 AS SPSCOUNTRY 
, 0 as SPSFuel 

, 0 as STCode 
, 0 as SageRev 
, 0 as SageQty 
, 0 AS SagePrj 

DECLARE @SAGESTARTDATE AS DATETIME, 
     @SAGEENDDATE AS DATETIME, 
     @SAGEITEM AS NVARCHAR(50), 
     @SPSSTARTDATE AS DATETIME, 
     @SPSENDDATE AS DATETIME, 
     @SPSCOUNTRY AS NVARCHAR(50) 

set  @sagestartdate = '2017-01-15' 
set  @sageenddate = '2017-01-15' 
set  @sageitem = 'diesel 50ppm' 
set  @spsstartdate = '2017-01-15' 
set  @spsenddate = '2017-01-15' 
set  @spscountry = 'dRC'

    Order by FleetNo 

Answer 2

Strans.[Description] COLLATE SQL_Latin1_General_CP1_CI_AS as FleetNo爲varchar你正試圖與SPSTr.FleetNo as FleetNo這可能是int，這是你的錯誤將其轉換爲varchar的原因convert(SPSTr.FleetNo as varchar) as FleetNo
