commit in a data step

Hi,

 

Can I do a commit in a data step similar to sql commits?

 

data tab2;

set tab2;

....

run;

 

For example, every 1000 rows.

 

Thanks

You may need to provide specific details on what your are attempting.

The OUTPUT statement is executeable and can be conditional so if you do something like:

 

Data tab3;

   set tab2;

   if mod(_n_,1000)=0 then output;

run;

you can get get every 1000 record. _n_ is an automatic variable indicating the record read, MOD is a function doing modular arithmetic.

 

BTW be very carefule using the Data table; Set table;  construct. Logic errors may mean that you destroyed the data you needed at a later step.
