tMap to join two Pandas tables

Anonymous — Sat, 16 Nov 2024 06:44:00 GMT

I created two python codes to run in tSystem which should put the tables into a variable and forward it to tMap.

The readout in the console works well, but how can I see the columns in tMap to join them to one table?

Thanks.

Hi,

If you are able to send the data to console, a good idea is to send them to tHashOutput components as the first stage.

Once you retrieve the data from both tSystem components to tHashOutput, then read the data from these Hash using tHashInput components and process them with tMap.

While reading back from tHashInput components, please don't forget to select the clear Hash after reading check box.

If you are not seeing these Hash Components in Palette, you can add them from below area.

File -> Edit Project Properties -> Designer ->Palette Settings -> Technical Components

Warm Regards,
