Hi All, Thanks for all your comments. I think I have more questions than I initially had. Which is good ! Now I understand the XY problem. I have a database which has 12 tables. The keys are column names from the excel sheet. This is my primary table and the rest in one to many relationship with this table. I have one value for the primary column in my LI table(COLUMN NAME LI) and can have multiple values for different columns in the same or different table. my $li_insert = "insert into LI values(LI_SEQ.nextval,?,?,?,?,?,?,?,?,?,sysdate,?,?,?,?)"; my $mechanism_insert = "insert into mechanism (TAGET,ACTIONTYPE,ID,LI_ID) values(?,?,MECH_SEQ.nextval,LI_SEQ.currval)"; Here one LI_ID can have multiple action_type or TAGET. So I want my script to be able to insert 5,2,1,12 6,1,2,12. The data would be like this: { 'taget '=> 5,6, 'Action_type' =>2,1 } in the excel sheet it actually comes as joined with a pipe operator I split them to have an array in a subroutine. How could I achieve this type of insertion if I keep them joined? Hope this is clear now!Let me know if you need any more details.
# to get each hash from an array of hash foreach my $results(@$hash_of_excel){ my $specificresults = GroupResults($results); } sub GroupResults{ #to getonly the relevant columns(excel) for each table in the database +. #%details is a global hash tha holds different tables and their corres +ponding column my( $AllRecords )= @_; my %specificResults; for my $info (keys %details){ $specificResults{$info}{$_} = $AllRecords->{$_} for @{$details{$in +fo}; } } return \%specificResults; } sub SomethingUnPipeModifyRecord { #convert the joined values to array of values my( $rec ) = @_; for my $val( values %$rec ){ my $newval = [ split /\|/, $val ]; $val = $newval; } return $rec; } sub insertLI{ my ($li_results )= @_; my $li_array_values = SomethingUnPipeModifyRecord($li_results); } sub insertMech{ my ($mech_results ) = @_; my $mech_array_values = SomethingUnPipeModifyRecord($mech_results);
