[Urgent] List the tables which are in a mapping using OMB ?

Question

Hello,
Does anyone know how I can list the table names which are contained in a mapping by using the OMB language ?
After with this list I'll retrieve the properties of the extraction and loading hints (by using the OMBRETRIEVE command).
Thanks in advance for your help !
Regards,
Florent

Hi Florent
Something like the following will retrieve the table operators in a map:
set table_ops [OMBRETRIEVE MAPPING '$mapname' GET TABLE OPERATORS]
As an example of navigating the map using OMB the tcl below will traverse the map (change the mapname variable and run in the context of the module containing the map) - the results are written to a textfile in /tmp/map.txt. You can see how the operators are navigated and the connections queried, each operator is listed and the connected operators.

set mapname EXAMPLE_17_21
set ops [OMBRETRIEVE MAPPING '$mapname' GET OPERATORS]
set fid [open "/tmp/map.txt" "w"]
foreach op $ops {
puts $fid ""
puts $fid "Operator: $op"
puts $fid "------------------------------------------------"
foreach top $ops {
set connected [OMBRETRIEVE MAPPING '$mapname' HAS CONNECTION FROM OPERATOR '$op' TO OPERATOR '$top']
if {$connected == 1} {
puts $fid " $op -> $top"
set grps [OMBRETRIEVE MAPPING '$mapname' OPERATOR '$op' GET GROUPS CONNECTED TO OPERATOR '$top']
puts $fid " Attribute Mappings"
puts $fid " ------------------"
set tgrps [OMBRETRIEVE MAPPING '$mapname' OPERATOR '$top' GET GROUPS]
foreach grp $grps {
set atts [OMBRETRIEVE MAPPING '$mapname' OPERATOR '$op' GROUP '$grp' GET ATTRIBUTES]
foreach att $atts {
foreach tgrp $tgrps {
set tatts [OMBRETRIEVE MAPPING '$mapname' OPERATOR '$top' GROUP '$tgrp' GET ATTRIBUTES CONNECTED FROM ATTRIBUTE '$att' OF GROUP '$grp' OF OPERATOR '$op']
foreach tatt $tatts {
puts $fid " $grp.$att -> $tgrp.$tatt"
close $fid
