Case I: windows 2000 professional, perl 5.6..., I was able to put it on my desktop and it works with the DBI 1.20 module from cpan. no problems.
Case II: windows 2000 server, perl 5.6..., I was able to load on this simple server and script runs with DBI 1.2 module from cpan. no problems.
Case III: Windows 2000 server, v5.6.1 built for MSWin32-x86-multi-thread ,I have a simple "hello world" type of file (test.pl) and it shows my hello message. I get the same download DBI 1.2 and then try to run my script (code will soon follow) and I get this error here and not on the first two cases.:
DBD::Oracle::db prepare failed: ORA-00942: table or view does not exist (DBD ERR OR: OCIStmtExecute/Describe) at C:\Perl\connect_2.pl line 28. Can't call method "execute" on an undefined value at C:\Perl\connect_2.pl line 2 9.
here is the code:
