Question

我们有一个非常简单的Crystal Report，只是从我们的Viewpoint数据库中提取有关作业的信息。唯一的参数是公司，部门和状态，每个参数的默认值都不会更改。

运行报表时，应使用已输入的新作业，新金额等进行更新。相反，所有数据保持不变，并且自上次运行报表后输入的作业不会显示

这是我们的代码：

SELECT 
  "JCJMPM"."Job",
  "JCJMPM"."Description",
  "JCCM"."ContractAmt",
  "JCCM"."JCCo",
  "JCCM"."Department",
  "JCCM"."ContractStatus",
  "JCMP"."Name",
  "ARCM"."Name"
 FROM   
  (("Viewpoint"."dbo"."JCJMPM" "JCJMPM" LEFT OUTER JOIN "Viewpoint"."dbo"."JCCM" "JCCM" ON ("JCJMPM"."JCCo"="JCCM"."JCCo") AND ("JCJMPM"."Contract"="JCCM"."Contract")) 
  LEFT OUTER JOIN "Viewpoint"."dbo"."JCMP" "JCMP" ON ("JCJMPM"."JCCo"="JCMP"."JCCo") AND ("JCJMPM"."ProjectMgr"="JCMP"."ProjectMgr")) 
  LEFT OUTER JOIN "Viewpoint"."dbo"."ARCM" "ARCM" ON ("JCCM"."CustGroup"="ARCM"."CustGroup") AND ("JCCM"."Customer"="ARCM"."Customer")
WHERE  
  "JCCM"."JCCo"=1 
  AND "JCCM"."Department"='50' 
  AND "JCCM"."ContractStatus"=1
ORDER BY
  "JCCM"."JCCo", 
  "JCCM"."Department", 
  "JCCM"."ContractStatus"

你有一个左连接：LEFT OUTER JOIN＆＃34; Viewpoint＆＃34;。＆＃34; dbo＆＃34;。＆＃34; JCCM＆＃34; ＆＃34; JCCM＆＃34; 和Where子句：WHERE
＆＃34; JCCM＆＃34;＆＃34; JCCo＆＃34; = 1 和＆＃34; JCCM＆＃34;。＆＃34;部门＆＃34; =＆＃39; 50＆＃39; AND＆＃34; JCCM＆＃34;。＆＃34; ContractStatus＆＃34; = 1

where子句将终止左连接并将其转换为内连接，将SQL更改为此连接并再试一次：

SELECT 
  "JCJMPM"."Job",
  "JCJMPM"."Description",
  "JCCM"."ContractAmt",
  "JCCM"."JCCo",
  "JCCM"."Department",
  "JCCM"."ContractStatus",
  "JCMP"."Name",
  "ARCM"."Name"
 FROM   
  (("Viewpoint"."dbo"."JCJMPM" "JCJMPM" 
LEFT OUTER JOIN "Viewpoint"."dbo"."JCCM" "JCCM" ON ("JCJMPM"."JCCo"="JCCM"."JCCo") AND ("JCJMPM"."Contract"="JCCM"."Contract")
AND   "JCCM"."JCCo"=1 
  AND "JCCM"."Department"='50' 
  AND "JCCM"."ContractStatus"=1
) 
  LEFT OUTER JOIN "Viewpoint"."dbo"."JCMP" "JCMP" ON ("JCJMPM"."JCCo"="JCMP"."JCCo") AND ("JCJMPM"."ProjectMgr"="JCMP"."ProjectMgr")) 
  LEFT OUTER JOIN "Viewpoint"."dbo"."ARCM" "ARCM" ON ("JCCM"."CustGroup"="ARCM"."CustGroup") AND ("JCCM"."Customer"="ARCM"."Customer")
ORDER BY
  "JCCM"."JCCo", 
  "JCCM"."Department", 
  "JCCM"."ContractStatus"

为什么我们的报告数据不会自动更新？如何在每次运行时更新数据？
