How is incrementing done in SAS proc sql?

edit

In SAS proc sql, incrementing can be done using the following ways:

1. Using the "INTO" clause to increment a variable value:

proc sql;
    select max(id)+1 into :new_id from my_table;
quit;

1. Using the "CALCULATED" keyword to increment a computed column value:

proc sql;
    select id, calculated id+1 as new_id
    from my_table;
quit;

1. Using the "DATA" step to create a new variable and assign it an incremented value:

data my_table;
    set my_table;
    new_id = id + 1;
run;

Note: The above examples assume the variable being incremented is called "id".
