False NULL values

Anonymous — Thu, 02 Aug 2018 15:10:07 GMT

Hi everyone

I come here with a problem I can't seem to solve no matter what i do.

I have a job in which i save data in a file (csv with "|" separator).

When i try to insert the data in my database (in the same job), i get the following error:

"ORA-01400: cannot insert NULL into ("MYDB"."ETABLISSEMENT"."ID_PMO")
Exception in component tDBOutput_1 (TransfertC_INIT_IEL_RG_TRT_09)
java.sql.SQLRecoverableException: Connexion interrompue"

But i checked my file and it does not contain a NULL value for this column, and it cannot contain one because it's a value i get from an inner join.

I've attached pictures of my job and map,

thanks for reading this and helping me.

Hi,

I would adjust your job flow around about first of all to help see whats going on. remove the "On Component OK" between tFileOutputDelimited_1 and tFileInputDelimited_1, and drop this later section down under the larger subjob - instead, put an "On Subjob OK" between tDBInput_1 and tFileInputDelimited_1.

To trace the null insert problem, I'd deactivate tDBOutput_1 and all later steps and add in a tLogRow and see what is actually coming out of tMap_6

Hope this helps

Thanks

David

Thank you very much, actually adding the "onSubJobOk" solved my problem.

I think the tFileOutput2 didn't had the time to close before lauching the subjob and this solved it.

Thanks again
