| Threaded Reads |
When Threaded Reads Do Not Occur
Threading does not occur under the following circumstances:
-
when a BY statement is used in a PROC or DATA step
-
when the OBS or the FIRSTOBS option is in a PROC or DATA step
-
when the KEY or the DBKEY option is used PROC or DATA step
-
if no column in the table exists to which SAS can apply the MOD function. For more information, see Autopartitioning Techniques in SAS/ACCESS.
-
if all columns within a table to which SAS can apply the MOD function are in WHERE clauses. For more information, see Autopartitioning Techniques in SAS/ACCESS.
-
if the NOTHREADS system option is set
-
if DBSLICEPARM=NONE
