關鍵字附近的語法不正確

Question

我有一個sql語句在sql server上成功運行，但在vb.net上粘貼時出現語法問題。不正確的語法靠近關鍵字'.','endfrom'和'group'。

sql = "select distinct y.supplierID, y.Name," & _ 
      "StatusDesc=CASE when y.status='N' then 'NEW' " & _ 
      "when y.status='B' then 'BLACKLISTED'" & _ 
      "when y.status='Q' then 'QUALIFIED'" & _ 
      "when y.status='R' then 'REJECTED' end , " & _ 
      "FlowStatusDesc = CASE when y.flowstatus='RC' then 'UNDER REVIEW'" & _ 
      "when y.flowstatus='PE' then 'POTENTIAL EXCLUSIVE'" & _ 
      "when y.flowstatus='PO' then 'POTENTIAL ORDINARY' ELSE '' end," & _ 
      "orderno=case when y.status='N' and y.flowstatus='' then '1'" & _ 
      "when y.status='N' and y.flowstatus<>'' then '2' " & _ 
      "when y.status='R' and y.flowstatus='' then '3'" & _ 
      "when y.status='R' and y.flowstatus<>'' then '4'" & _ 
      "when y.status='Q' and y.flowstatus='' then '5'" & _ 
      "when y.status='Q' and y.flowstatus<>'' then '6'" & _ 
      "when y.status='B' and y.flowstatus='' then '7' " & _ 
      "when y.status='B' and y.flowstatus<>'' then '8' else '9' end " & _ 
      "from (select x.supplierID, x.Name,x.Status,x.FlowStatus,x.AddWho" & _ 
      "from dbo.AP_Supplier x where x.AddWho IN (Select distinct b.UserID from dbo.SC_UserRole a left join dbo.SC_UserRole b ON a.RoleID=b.RoleID where a.UserID=@User)" & _ 
      "group by x.supplierID,x.Name,x.Status,x.FlowStatus,x.AddWho)y " & _ 
      "group by y.supplierID,y.name,y.status, y.flowstatus" & _ 
      "order by orderno" 

Answer 1

在所有行的末端插入空格。例如。

"group by y.supplierID,y.name,y.status, y.flowstatus" & _ 
"order by orderno" 

結果字符串

group by y.supplierID,y.name,y.status, y.flowstatusorder by orderno 

這是一種語法錯誤英寸
