Description Ian Walls 2011-10-19 00:16:44 UTC
my $tablename and my $hash are globally defined in C4::SQLHelper, but are never used; all subroutines use a locally scoped $tablename, and $hash is never used, locally or otherwise.

Removing these two lines may help ensure mod_perl compatibility (since variables in subroutines cannot safely alter values in outer script in persistent environments).  Or not.  If nothing else, it's just a bit a trivial cleanup.

Comment 2 laurenthdl 2011-10-19 15:06:50 UTC
idea was to use the hash to store the whole database structure and use that rather than making a SHOW TABLE never been implemented because of time.
It should help to store the database structure somewhere in some way.
Would it be DBIC schema, or a yaml file no preference. But should be in our mind though

[SIGNED-OFF] Bug 7061: unnecessary global variables declared in C4::SQLHelper

Removes $tablename and $hash from global scope of C4/SQLHelper.pm.  They are never used;
all instances of $table are locally scoped to the subroutines, and $hash is never used.

This may help with persistance; if not, it's at least a bit of trivial cleanup.

To test:

1.  Search for a patron
2.  Create a Contract in Acquisitions
3.  Modify that Contract
4.  Delete that Contract

All instances should return error free.  This checks the subroutines of SQLHelper
