Dropping Data from a Temp Table

[Tarquinius]

Hi,

I have a continual delivery workflow that is looking for an External signal to activate.

As part of the workflow, I pull in a List for lookups against c1.4 million rows. Not ideal but best way of circumventing an issue. 

The workflow runs and sends the emails.

However the list never seems to get dropped but holds the data in a temp table (temp:readGroup). Is there anyway of dropping this data via a JS node once the email has sent? It's putting strain on the server since the workflow never really 'ends' continually eating memory when not needed etc.

Hope that makes sense!

Hi @Tarquinius , 

If I understand correctly,  we have the OOTB functionality in the List Update activity to purge the list entirely. 

which can be used after the delivery is sent out.

Thanks,

Thanks for the response @adithyacs86 

Sorry. I may not have explained myself very well though!

The list is reused over and over each time the workflow is triggered. The problem is when the data is loaded into a temp table within the workflow, it's not getting dropped once the workflow has completed (probably because the workflow has a continual delivery and therefore never truly 'ends'). I don't want to purge the list - just the temp list load from the workflow (temp:readGroup by the looks of it).

I was hoping there might be a bit of JS code I could use in a node to simply purge the data in the table (temp:readGroup).

Thanks

Hi Again, Sorry I misread the details, thanks for clarrifying, yes I think you can use either SQL code activity or the write sql script in the JS activity after the delivery activity to delete the temp table, like "DELETE FROM vars.tableName;" this would delete the entires in the temp table.

Hello @Tarquinius ,

First open the list and get the SQL table name from the content tab.

The you can use this code in the JavaScript activity in the end of the workflow:

sqlExec("TRUNCATE TABLE TABLE_NAME_HERE");

Thanks,

Manoj

Hi @Tarquinius ,

1. Put an end block after cont. delivery block.
2. Use this in the advanced tab of end block:

sqlExec("drop TABLE "+vars.tableName);

vars.tableName with contain the temp table name that gets created in backend database. It will have name like wkf1163548174_64_1

Thanks,
