I have created a prallel job in which i have source db2 connection, a transformer and a sequential file as output file. I just want to get the data from db2 source into a sequential file without any transformation.
When i try to run the job, i get the following error.

DB2_UDB_API_10,0: Field type must be string in order to call setOutputFieldAsString() for field '37' in output dataset '0'.

I can view data in DB2 source stage without any problem, and iam not doing any transformation in the transformer, just passing the output to sequential file through transformer.

Can anybody have an answer for it? please help me out.

Search is your friend. Reference this similar post.

i have tried to change the extended code....but still it is not working.

What is sqltype and length of field 37? With the first column starting from 0. Do you have NLS enabled?

these are the error iam getting:


DB2_UDB_API_10,0: Info: DB2_UDB_API_10: Using NLS map ISO-8859-1
DB2_UDB_API_10,0: Field type must be string in order to call setOutputFieldAsString() for field '37' in output dataset '0'. (fatal)
DB2_UDB_API_10,0: Operator signalled one or more errors.(fatal)
DB2_UDB_API_10,0: Output 0 produced 0 records.
Sequential_File_2,0: Export complete. 0 records exported successfully, 0 rejected.
APT_CombinedOperatorController,0: Operator's runLocally() failed.(fatal)
APT_CombinedOperatorController,0: Operator terminated abnormally: runLocally did not return APT_StatusOk (fatal)
main_program: Step execution finished with status = FAILED.

You have NLS enabled in DataStage. But is it enabled in the database. Disable NLS and then run the job.

I have 55 columns in my db2 file. Now the job running since i removed the extended type (unicode) for all the columns. In this file i have also some timestamp columns. Physically i got an output sequential file created. but when i try to view data from data stage i get this error.

Are you building a fixed width file or a delimited file? make sure you have correct lengths for all those listed columns.

Could you please let me know what kind of data ur trying to extract for the I/P.Is it mainframe DB2 data.DB2 is very particular about the sql types.

The message says not to use the setOutputFieldAsString() function unless the target data type is string (that is, Char or VarChar).
