在 Talend 中为特定代码生成特定密钥

Question

我想为 talend 中的特定代码生成特定数字。有些代码是重复的，但我不想为该代码生成不同的数字序列。在 tMap 中，我使用了 Numeric.sequence("out1.CODE",1,1) 但它没有帮助。有没有办法根据之前匹配的代码替换key。请帮忙

Table 1

code
ABC
ACC
AEB
ACC
AED
BEE
AEB

要求的结果

Table 1

code	key
ABC	1
ACC	2
AEB	3
ACC	2
AED	4
BEE	5
AEB	3

Answer 1

你的工作设计应该是这样的

1- tMap_2 is configured as such

2- thashinput_1 would call thashoutput_1 and tick in the tUniqRow_1 : **Code**

3- tmap_4 configuration is configured as such :

4- tmap_5 configuration is configured as such :

Here is my output :

Starting job string at 16:22 10/05/2022.
[statistics] connecting to socket on port 3404

 .----+---.
 |tLogRow_3|

 |code|key|

 |ABC |1  |
 |ACC |2  |
 |AEB |3  |
 |AED |5  |
 |BEE |6  |
 |ACC |2  |
 |AEB |3  |

 [statistics] disconnected

 Job string ended at 16:22 10/05/2022. [exit code  = 0]
