问题是: Pentaho PDI没有将上一步的“结果”行用作转换参数。
故事:我需要在第一个转换步骤中捕获一个fee_key,并在下一步中计算费用。职位:job_test_parameter
我做什么:
查询Fee_key = 5并在trans_get_fee_key
设置trans_calc_fee转换参数:
"Options"->"Execute every input row" is ON
"Parameter"->"Copy results to parameters" is ON
对于SQL:
SELECT ${FEE_KEY}*100 as FEE FROM DUAL;
我遇到错误:
2018/07/18 13:34:19 - SQL with Parameter.0 - An error occurred executing SQL:
2018/07/18 13:34:19 - SQL with Parameter.0 - SELECT *100 as FEE FROM DUAL;
2018/07/18 13:34:19 - SQL with Parameter.0 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '100 as FEE FROM DUAL' at line 1

其他检查:
如果我在输入参数FEE_KEY的转换“ Parameters”中设置默认值(例如= 3),则一切正常。
如果在计算步骤从行结果中获取FEE_KEY,则它具有值并能够写入日志。
