Hi Team,
Can i embed db2 select query in a script and call that script via jcl using BPXBATCH utility. i have a requirement where i need to frequently perform search(select *) from multiple db2 tables of same schema and extract data to flat files and send across to different server.
How do i achieve this , and other way or links or sample code. Please let me know
Thanks! |

What prevents you from using the simplest JCL?
1) unload required tables into flat files via standard utility, and
2) FTP all files to the servers you need
Maybe, 50% of existing requirements are exactly what you need, but none of them does require any complex mechanism to achieve this.
What is so specific in your requirements that you need to make simple things so complicated for no reason? |

The code may be site-specific, customized by your support. Generally it may look like this one, with possible tons of variations
| Code: |
//********************************************************************
//* UNLOAD THE TABLE DATA INTO SEQUENTIAL DATASET(S)
//********************************************************************
//UNLOAD EXEC PGM=IKJEFT01,DYNAMNBR=20
//STEPLIB DD DSN=syshlq.SDSNLOAD.db2id,DISP=SHR
// DD DSN=syshlq.RUNLIB.db2id,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
DSN SYSTEM(db2id)

//SYSPRINT DD SYSOUT=*

You cannot start doing something with zero preliminary knowledge (as per your questions, and used terminology). You desperately need:
1) to read, and to learn aggressively a lot of things about programming in general, and mainframe specifics in particular.
2) to consult with your support team: what are the tools available at your environment, with their comments, and examples. |

No response should be expected unless your code samples are properly <coded>, and properly aligned.
P.S.
The appeal “I’m getting errors” cannot be resolved anyway, without clarification of the error(s).
It is equivalent to “My car did not start, what is wrong?” |
