I want to add SEQNUM variable in below dataset and I want numbering to get re-started from 1 as soon as EMPID changes....means for first 8 record SEQNUM should have normal....1, 2, 3...8 but for 9th record EMPID changed then it should have again 1, 2, etc. Like this for entire table.

Any easy way to do this.

I want to use proc sql only.

Can we do this same operation in proc sql step, without using data step?

Basically, no. SQL has no concept of sequence. There are methods to trick SQL into doing this, but they often rely on the use of undocumented (and therefore unreliable and dangerous) features. Apart from being (much) less performant than a data step.
