Hello again... OK.. it's been a long time since I've had to deal w/this issue, but now I have to finish up with it. I am going to post all the code from the script and then I will tell you what I need and can't figure out. I guess I'm what one might call a "code-rock"... just can't penetrate my brain w/the information!
I'm running on WindowsNT server w/Perl v.5.06... The script runs now, but I have to make it more specific to the data that is pulling in, more unique to the lines from the database. Again I have the Perl Cookbook and Perl in a Nutshell and have gone online to all sights figuring this out, and I humbley come here...
I connect no problem, extract what I need, then update. This all works. Now I need to select in 2 fields, not one.
I am selecting a field where exe_c = 'N'. Now I also need to select were exe_c = 'N' and rowid = ? (unknown). The rowid is the identifier generated in Oracle that I don't know, but is unique to the row that I'm pulling in. After the row is selected and worked on in the loop, I would like to update exe_c from 'N' to 'Y' where exe_c = 'n' and the rowid = ?.
$asql = "SELECT batch_line, rowid FROM xyz.batch_lines WHERE exe_c = 'N' ";
but how would I still do the work to the batch_line that I'm taking in AND take in the rowid as a variable (which is unknown) then use it (or bind it, which I tried but can't figure out) to the UPDATE statement?
$bsql = "UPDATE xyz.batch_lines SET exe_c = 'Y' WHERE exe_c = 'N' AND row_id = ? ";
The following is the script that I am currently running. Thank you for all the help in advance.
