Question

I’m trying to load a table, create an index, collect statistics, grant select permissions on a table in teradata using SAS to complete the work. SAS is the only piece of software I have to choose from.

The following script successfully deletes the table, load the table, creates the indexes but doesn’t collect statistics or grant select. Is there another way of doing this, or am I doing this incorrectly?

libname ias teradata server=<server> USER=&tduser. schema=<dbname> password=&tdpass.;

proc datasets library=ias;
   delete <tablename>;
run;

data ias.<tablename> (bulkload=yes sleep=10 tenacity=4 dbcommit=80000);
  set WORK.<data set name>;
run;

proc sql;
    connect to teradata as td (user=&tduser.  password=&tdpass. tdpid="<server>" schema="<dbname>");
    execute(create index <indexname> (<columnname>) on <dbname>.<tablename>) by td;
    execute(commit) by td;
    execute(collect statistics on <dbname>.<tablename> index (<columnname>);
    execute(commit) by td;
    execute(grant select on <dbname>.<tablename> to <list of users>) by td;
    execute(commit) by td;
disconnect from td;
run;

Everything looks fine to me. How do you know the COLLECT and GRANT commands did not work? Did you get an error message?

A couple notes:

In your PROC SQL CONNECT statement, I suggest that you add the option MODE=TERADATA; that will put the connection in “Teradata” rather than “ANSI” mode, one benefit of which is that commands are “committed” automatically; you do not need those “commit” steps.

Also in your PROC SQL CONNECT statement, you are specifying the SCHEMA option; I don’t think that has any effect. Everything in the EXECUTE block must be pure Teradata syntax, so fully qualify all table references.

Be sure that your COLLECT STATISTICS statement is on “index ()” not “index().

Finally, I strongly suggest that you explicitly define the tables primary index and data type using the DBCREATE_TABLE_OPTS and DBTYPE data set options when you create the table, something like:

data ias.<tablename>
     (bulkload-yes sleep=10 tenacity=4
      dbcreate_table_opts='primary index(<columnname>)'
      dbtype=(  <columnname>='<teradata column definiton>'
              , <anothercolumn>='<teradata column definition>'
             ));
       set WORK.<data set name>;
run;

If you do not name the index explicitly, the first variable in your SAS data set will be selected for the index (which may or may not be correct), and the data type might not be appropriate.

If you still have problems, post back with any error messages; and please use an exact example (don’t hide column and table names with bracketed references).
