如何在不使用SQL沙箱的情况下使用SAS数据集创建易失表inn Teradata

Question

I have a SAS dataset and I need to create a volatile table in Teradata using the SAS dataset. But, I do not have a sandbox to store the table on Teradata server. Is there a way that I can create a Teradata volatile table from a SAS dataset without SQL Sandbox.

Answer 1

It is pretty simple to create a volatile table in Teradata, just use the dbmstemp=yes option on your libname statement.

libname TDWORK teradata connection=global dbmstemp=yes .... ;
data tdwork.test1 ;
  set sashelp.class ;
run;

Make sure to use the connection=global option on all of your LIBNAME and CONNECT statements so that all of the connections to Teradata use the same session so you can see your volatile table. Keep at least one of the libref's open so that the connection persists.

Then you could also use passthru SQL to create a volatile table.

proc sql ;
  connect to teradata (connection=global .... );
  execute (
    create volatile table test2 as (
      select * from test1
    ) with data on commit preserve rows 
  ) by teradata;
quit;

Or to reference the volatile tables in pass thru SQL code.

So if you wanted to pull out of Teradata all the records from MYDB.MYTABLE where NAME was in the list of names you uploaded into the volatile table TEST1 you made with the first data step above you could use code like this:

proc sql ;
  connect to teradata (connection=global .... );
  create table mytest as select * from connection to teradata 
  ( select * from mydb.mytable 
    where name in (select name from test1)
  );
quit;
