This question belongs in [EMAIL PROTECTED], _NOT_ dbi-dev.
If this is new code, I strongly recommend using DBI instead of Oraperl.
Oraperl.pm is just a wrapper around DBI calls for Oracle, so you are using
it inadvertently anyway. The newer interface provides several ways to check

You can only put a single data value in each placeholder, no lists. Run

"bind_param" for examples and limits.
If all you are passing are numbers or strings, you can skip bind_param() and
include the bind variable values
This is the DBI list, so database connectivity is not off topic. Normally

This is a Perl question, not a DBI one. The problem is most likely
happening at the point of return from the subroutine. 'return %start;' is
being evaluated in a scalar context because you are assigning the subroutine

You definitely need at least Pro*C/OCI and SQL*Net to _BUILD_ DBD::Oracle.
You also need to build DBI first.

You can usually connect to most any Oracle 7 or Oracle 8 instance as long as

What might cause trouble is if DBD::Oracle was compiled against one version

the Oracle client software.
