从SQL中的两个查询计算

Question

我有2个查询给我数。我想对方将一个数 - 目前，我有下面的SQL，而是立即抛出错误：

SELECT tbl_CEAR_Name.CEAR_Team, 
      Q_Manager_Backlog_Total.Backlogs, 
      Q_Manager_CHS_Total.CHS_Total, 
      [Q_manager_CHS_Total].[CHS_Total]/[q_managers_backlog_total].[backlogs] AS Expr1 
FROM Q_Manager_CHS_Total 
INNER JOIN 
(
    Q_Manager_Backlog_Total 
    INNER JOIN tbl_CEAR_Name 
     ON Q_Manager_Backlog_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team 
) 
    ON Q_Manager_CHS_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team 
ORDER BY Q_Manager_Backlog_Total.Backlogs DESC; 

Answer 1

你完全banjaxed您的联接尝试这种

SELECT tbl_CEAR_Name.CEAR_Team, 
     Q_Manager_Backlog_Total.Backlogs, 
     Q_Manager_CHS_Total.CHS_Total, 
     [Q_manager_CHS_Total].[CHS_Total]/[q_managers_backlog_total].[backlogs] AS Expr1 
FROM Q_Manager_CHS_Total 
INNER JOIN 
(
    select Q_Manager_Backlog_Total.Backlogs, tbl_CEAR_Name.CEAR_Team 
    FROM Q_Manager_Backlog_Total 
    INNER JOIN tbl_CEAR_Name 
     ON Q_Manager_Backlog_Total.CEAR_Team = tbl_CEAR_Name.CEAR_Team 
) T1 
    ON Q_Manager_CHS_Total.CEAR_Team = T1.CEAR_Team 
ORDER BY Q_Manager_Backlog_Total.Backlogs DESC; 

Answer 2

我怀疑伯爵查询[q_managers_backlog_total]中的字段[backlogs]的结果为0。如果你然后尝试除以0，你显然会得到一个错误。在基础查询中捕获一个0值，你很好。
