TR_ENABLE_INTERRUPT=YES | NO

Syntax Description

YES: allows interruption of long-running SQL processes that are involved in creating the result set or spool file.

NO: disables the interrupt processing code path.

Details

When set to YES, here is how you can use this option:

to interrupt any SELECT SQL statement that was submitted by using the SELECT * FROM CONNECTION as a pass-through statement
by using the Interrupt/Attention button to interrupt a query that you submitted through a DATA STEP, through PROC SQL implicit pass-through, or through explicit pass-through

Once the result set or spool file forms on the Teradata server and SAS is fetching the results, it is likely that the interrupt might no longer be available and you must wait until all results are fetched. The interrupt works in only one of these cases:

when the Teradata server is building the result set or spool file.
if the Teradata server is in a wait state before building the result set or spool file because of locking.

Example

libname x teradata user=sasias pass=sasias
  TR_ENABLE_INTERRUPT=YES server=tera2650;

data _NULL_; set x.paul_test; run;

proc datasets lib=x; quit;

proc sql;
create table work.a as select * from x.td_cancel, x.td_cancel;
quit;

proc sql; connect to teradata (user=sasias pass=sasias
  TR_ENABLE_INTERRUPT=YES server=tera2650);
select * from connection to teradata 
  ( select * From td_cancel a , td_cancel b );
quit;
