i am getting the count of 36605480 obs in resultant dataset, i want APC count in my dataset.

You have multiple matches for your key variable pairs in IOTC, causing a multiplication.
Do a
proc sort data=iotc out=test nodupkey;
by ins_op_code type_cov_code;
run;
and look at the log.
Try this. In your posted code, you did not reference the table APC as a.
proc sql;
create table APC_1 as
select a.*, b.PROD_NAME
from APC as a left join IOTC as b
on a.INS_OP_CODE =b.INS_OP_CODE and a.TYPE_COVERAGE_CODE=b.TYPE_COV_CODE;
quit;
sorry its typo error.
its referred as a in the code.
Ok. Can you post your log please?
