SET BULKLOAD OPTIONS (POSTGRES ENGINE) TO SCD2 TRANSFORMATION IN DIS

Egrodrigues2014 — Sun, 30 Oct 2022 19:49:47 GMT

Hi everyone,

When I set BULK LOAD option as active, SCD2 transformation create the following code (for ETLS_CLOSE as example):

      proc append base = EXT_VI."W6B3BTSM"n
         (
            BULKLOAD=YES
         )
         data = work."ETLS_CLOSE"n force; 
      run;

But this code doesn't work. I need to set "bl_psql_path='/PATH' " and "bl_delete_datafile=no" dataset option to BULKLOAD works properly.

I aware that I can change the automatic generated code to add these options.

Is there a way to configure these options at the transformation level? Or a way that I can add these options without change the code manually?

Thanks in advance.

Unsure if you can do this using standard options in the transformation.

But I am wondering if you have a good use case here.

S in SCD stands for Slowly, so you shouldn't have millions of records that needs closing out.

If not done so already, you could try the SQL Pass through option, it might speed up the process depending on the performance of your RDBMS.

Hi @LinusH ,

We need to load the historical records and this data volume will be only in the first iteration.

As you can see, we change the option "Upload library before targe table update" to EXT_VI library. But the "etls" tables still in work library.

/* Delete the work tables  */ 
      proc datasets lib=EXT_VI nolist nowarn memtype = (data view);
         delete "W6B3TJ5F"n;
         delete "W6B3TIUB"n;
         delete "W6B3TIOR"n;
      quit;   
     
         proc datasets lib=work nolist nowarn memtype = (data view);
            delete etls_newrcds;
            delete etls_match;
            delete etls_close;
         quit;

To load data from work to postgres tables, we need to set bulkload.

Is there a way so that these tables are also generated in the "EXT_VI" (postgres) library ? Thus, passthrough can be performed without the need for BULKLOAD.

We set "Libref to copy temporary work tables to" SCD option to EXT_VI, but it does not work.

Thanks in advance.
