Qlikview Lookup Function

This post demonstrates the use of the Qlikview Lookup Function.  For my use case, I am connecting to SQL Server Express 2014, using the AdventureWorks2012 database.  I connect and pull in the “all_objects” system table, then build a second table using the LOAD Resident technique.

Qlikview Version:  Personal Edition 12.0.20100.0 SR2 64-bit Edition (x64)

OS:  Windows 10

Database:  SQL Server Express 2014

Setup – Qlikview Lookup Function:

First, open and save a new Qlikview QVW file, then connect to SQL Server and pull in the all_objects table, using the following LOAD SCRIPT:

Next, add a table box object like the following:

At this point, notice the field “parent_object_id” above.  It would be nice to see the object name and type for this parent_object_id.  Here is where the Qlikview Lookup Function comes into play!

Here is how to accomplish this next step.  Add the following to your LOAD SCRIPT:

Here, we added two additional tables to the script:

  • ObjectHierarchy – created by taking the “object_id” and “parent_object_id” out of all_objects table, and using Resident LOAD to build the new table
  • ParentObject – created again by taking the “parent_object_id” out of the all_objects table, and adding two additional columns using the Qlikview Lookup Function

Qlikview Lookup Function:

  • ParentObjectName – This field was created by Lookup(‘name’, ‘object_id’, parent_object_id, ‘all_objects’)
    • Parameter 1:  ‘name’ – This is the field we are looking up
    • Parameter 2:  ‘object_id’ – This is the field in the lookup table (all_objects) we want to lookup, against a value in our source table (ParentObject)
    • Parameter 3:  parent_object_id – This is the field in our source table (all_objects) we are using to lookup against key field in lookup table (object_id in all_objects table)
    • Parameter 4:  ‘all_objects’ – This is the lookup table we are searching for the desired value (‘name’)
  • ParentOjbectType – Using the same Lookup function as above, pulling in the ‘type_desc’ field from the lookup table
    • Lookup(‘type_desc’, ‘object_id’, parent_object_id, ‘all_objects’)


Now, Reload the QVW, and you will then have a data model that looks like the following:

Qlikview Lookup Function

Now, back in your QVW file, add another table box object to display the ParentObject contents:

Finally, bringing it all together, if you select a “parent_object_id” in the table box for all_objects table, you will then see the second table box (ParentObject) update to display the object name and object type of the actual “parent_object_id”:

That should do it!  Please modify to suit your needs.
