Issues when uploading to an existing Teradata table which contains the previous data

[wg]

Hi, how can I upload data to append to an existing Teradata table in SAS?

Thank you

[Tom]

libname td teradata server= ..... ;

proc append base=td.existing  data=new_data ; run;

[wg]

Hi Tom... Thank you very much ... But I have 9,000,000 obs to upload. You method may take very very long time to load...

[Tom]

Why do you think it will take a long time?

You can use the FASTLOAD option, but that requires an empty table.  So load to an empty table then use passthrough code to insert it into the target table.

Fastload can only be done for appending data to an empty table. But I kept history data there. So I cannot use Fastload...

Load into an empty table and the copy on the TD side.

proc sql ;

  connect to teradata (....);

  execute (insert ..... ) by teradata ;

quit;
