Hi all,
I would like to update a DB2 table row using a query similar to this..
| Code: |
UPDATE <TABLE>
SET <Column-1> = <Host Variable-1>
WHERE <Column-2> = <Host Variable-2>
|
How do I do that in a REXX Program?
Thanks in advance |

Well, once the funds have cleared, 750 per day or part there of - code will be delivered.
DO NOT ask for code without at least showing what you have coded yourself and what the errors are. Asking for code like that is downright lazy !!!!! |

This will get you started:
| Code: |
/* rexx */
/* add your logic here */

Thanks expat!
The Redbook DB2 for z/OS and OS/390 : Squeezing the Most Out of Dynamic SQL has it all
My
| Code: |
/* REXX */
ADDRESS TSO "SUBCOM DSNREXX"
SQLSTMT = "UPDATE AGENT SET ADDRESS = ? WHERE AGENTID = ?"
SAY 'ENTER YOUR ID'
PULL AGENTIDA
SAY 'ENTER YOUR NEW ADDRESS'
PULL ADDA
ADDRESS DSNREXX
"CONNECT DSN1"
"EXECSQL DECLARE C1 CURSOR FOR S1"
"EXECSQL PREPARE S1 FROM :SQLSTMT"
"EXECSQL EXECUTE S1 USING :ADDA, :AGENTIDA"
IF SQLCODE = 0 THEN
SAY 'UPDATE SUCCESSFUL'
ELSE
DO
SAY 'UPDATE OPERATION FAILED. ERROR DETAILS ARE'
SAY 'SQLCODE' SQLCODE 'AND SQLSTATE' SQLSTATE
END
"DISCONNECT DSN1"
|
I am sorry for asking for the code before trying anything..
I am now happy I know Dynamic SQL (I have read that 290 page book and only then started coding). |

Great to see that you have done it.
Don't forget the SQLCA parts which will get any error messages and codes. |

Impressive. I usually only read the page that I need. Knowing which manual to use is 99 percent of the battle. When I need more, I read more of it. |
