以逗號分隔的源文件，然後使用java轉換來分割行

Question

我有一個逗號分隔的源平面文件，文件具有開始日期和結束日期的標題，下一行包含所有提交的名稱並繼續源文件的數據 例如：

"2015-05-09","2015-06-05"

所以現在我與1000精密閱讀它作爲一個長字符串，然後我想用Java轉換，並將它們與在多個標題蔓延列名，和準分裂他們與下面的值。一個輸入行將着陸許多目標行。

第一件事：逐行讀取文件到一個長串端口。

將「CurrentlyProcessedFileName」端口添加到源以捕獲文件名。
計算讀取的行數

在逗號分隔行 - 我該如何實現？猜測表達式或Java轉換和下面的整個過程在Java中或我可以使用SP，BU如何分割行上的逗號？

If Current RowNumber = 1 Then  
     vINVC_BGN_DT := field1 
     vINVC_END_DT := field2 

    If Current RowNumber > 1 
     If field1 != $$CARRIER Then 
    NAME1 := NAME1 || field1 #Initialize NAME variables to an empty string 
    NAME2 := NAME2 || field2 
    NAME3 := NAME3 || field3 #repeat for each comma seperated field 
     If field1 = $$CARRIER Then 
    VALUE1 := field1 
    VALUE2 := field2 
    VALUE3 := field3   #repeat for each comma seperated field 

對於每個源行，輸出行的數量應等於不同Amount_types的計數，（不包括空的）

For i in NAME4.NAMEx loop 
     if NAMEi is not spaces or null then generate row 
      target.INVC_TYPE = "CLAIM" 
      target.FILE_RECEIPT_SK 
      target.CARRIER := VALUE1 
      target.CNTRCT := VALUE2 
      target.PBM_GROUP := VALUE3 
      target.INVC_BGN_DT := vINVC_BGN_DT #From row1 
      target.INVC_END_DT := vINVC_END_DT #From row1 
      target.INVC_AMOUNT_TYPE := NAMEi 
      target.INVC_AMOUNT := VALUEi 
    end i loop.. 

Answer 1

可以使用歸一化到一個行分成多行。你的情況，你必須分開處理第一行，接下來的3個標題行和數據行。爲此，在使用變量的表達式中創建seq否。

您可以在表達式本身中獲取開始日期和結束日期：例如，

begin_date:= iif(seq=1, field1, begin_date) 

對於分離該標題行和數據行，請使用條件柔兒像seq>1 && seq<=4和seq>4

現在你可以使用一個歸一化於行拆分爲多個行。對於數據行，爲載體，合約，pbm_group，計數和金額創建5列，並將計數和金額的發生設置爲總數。或計數或金額欄。

您可以對標題列同樣使用另一個標準化程序。最後使用joiner轉換連接兩個流。

您也可以使用java轉換，在輸入行選項卡上，您已寫入類似的邏輯。爲了分割行，你可以使用split方法。例如：

String[] fields=row.split(","); 

現在陣列fields將包含所有字段的數組元素。您可以將適當的元素分配給輸出端口，並調用Informatica的generateRow()方法來創建目標記錄。
