Hi,
I am trying to connect REXX with DB2.This is my first code of working with DB2 in REXX. The error below says the module is not found where i checked in library and came to know that it is in library "***GRP.SDSNLOAD" . I tried to include in the REXX code as below but getting error.
| Code: |
/*REXX*/
TRACE(?)
SUBSYS="***"
QUERY="SELECT * FROM ***.TABNAME"
ADDRESS ISPEXEC "LIBDEF ISPLLIB DATASET ID('****GRP.SDSNLOAD')"
ADDRESS TSO "SUBCOM DSNREXX"
IF RC THEN
S_RC=RXSUBCOM('ADD','DSNREXX','DSNREXX')
ADDRESS DSNREXX "CONNECT" SUBSYS
IF SQLCODE <> 0 THEN COUTPUT SQLCA
ADDRESS DSNREXX "EXECSQL DECLARE C1 CURSOR FOR S1"
IF SQLCODE <> 0 THEN CALL SQLCA
ADDRESS DSNREXX "EXECSQL PREPARE S1 FROM :QUERY"
IF SQLCODE <> 0 THEN CALL SQLCA
ADDRESS DSNREXX "EXECSQL DESCRIBE S1 INTO :OUTPUT"
IF SQLCODE <> 0 THEN CALL SQLCA
ADDRESS DSNREXX "EXECSQL OPEN C1"
IF SQLCODE <> 0 THEN CALL SQLCA
DO UNTIL (SQLCODE <> 0)
ADDRESS DSNREXX "EXECSQL FETCH C1 USING DESCRIPTOR :OUTPUT"
IF SQLCODE = 0 THEN
DO
SAY " > COLUMN NUMBER: " I
SAY " COLUMN NAME: " OUTPUT.I.SQLNAME
SAY " COLUMN TYPE: " OUTPUT.I.SQLTYPE
SAY " COLUMN VALUE: " OUTPUT.I.SQLDATA
END
END

I get error as below :

I read some threads of this forum about this and saw that ISPEXEC cannot be used in ***GRP.SDSNLOAD....
Can someone please help me in understanding what the actual problem as still i am not clear and help me to connect to DB2 through REXX.
Thanks,

LIBDEF is used for ISPF service calls. SELECT CMD(mycmd) or SELECT PGM(myprog) will find your module in the LIBDEF, but it is not part of the normal z/OS search order.
I think you can do either of these:
1. add "***GRP.SDSNLOAD" to your STEPLIB concatenation of your logon proc. Most people are not authorize to do this.
2. Use TSOLIB command to add "***GRP.SDSNLOAD" to the search order. Do this before starting ISPF
3. Add "***GRP.SDSNLOAD" to the ISPLLIB concatenation before starting ISPF. |

Add to the ISPLLIB means how do I do it. Sorry I couldnt get this point..... |

This is the option that we use in our shop. The funny thing is, most of my DSNREXX applications had been needlessly LIBDEFing SDSNLOAD for many years. I had this reinforced when one of our test DB2 subsystems was upgraded to V11 and all of my apps started breaking on -805 sqlcodes. No amount of LIBDEFing could get me out of it; I had to change the ISPLLIB concatenation in our logon proc.  |

or speak to Your support to find out if the steplib command is available
one can be downloaded and installed from the cbttape,
ASK YOUR SUPPORT
if used well it is one of the most useful tools around |

Is there no other way other than communicating with the support team. |

We don't make such suggestions without thought. When you are told to work with your site support group, it is because there is a lot of z/OS that is customized at each site so what works for one site will utterly fail at another site. And you are asking about data that is specific TO YOUR SITE -- and nowhere else. So unless you talk to your site support group and get information specific to your site, you cannot proceed. |

There are several file types associated with ISPF. For example, when your program says to display a panel, ISPF searches for it in the panel library concatenation, ISPPLIB. Likewise, when ISPF is searching for load modules it searches in the load module concatenation, ISPLLIB.
Concatenations are just data sets allocated to a particular file name.
I think what you want to do is add your DB2 data set to whatever is already allocated to ISPLLIB. Ask your support if you have the CONCAT or CONCATD command. |

Thanks, I found the solution and have got doubt on another line ,
When using FETCH we specify the field names after FETCH INTO but what is i want to fetch the entire table ways based on the table name the user mentions....?
Can you give some idea on it...? |

| Regarding DB2 stuff, I think you will get better answers by asking in the DB2 forum. |

What is "the entire table ways" ? |

Don't know about DB2 but with Rexx on the PC using RexxSQL to access an SQLite database simply do a SELECT without a WHERE and fetch rows until rowcount is 0.
OK - a few hours later I have found an old m/f Rexx program that processes a cursor: SELECT followed by FETCH followed by a loop processing the returned rowand FETCH the next row until FETCH gives non-zero return code. |

If the name of the table is not known to the program because it is supplied by the user, then you will have to deal with the SQLDA. |
