Hema_12 — Wed, 01 May 2019 00:23:34 GMT

Hi All,

query;- i need to delete the rows which are older than 10 days and set id=1 with auto increment value.

database is teradata;

please suggest possible solutions.

Thanks in advance.

i have written this piece of code

------------------------------------------

options mprint mlogic symbolgen;
%macro clean;
data one;
set work.process_cleanup;
today= today();
/*max_date=max(start_datetime);*/
max_date_1=datepart(start_datetime);
/*seven_date=intnx('day',today,-7);*/
format today date10. max_date_1 date10. /*seven_date date10.*/;

/*%if max_date_1<today %then %do;*/
/*output out_t;*/
proc sql;
delete from work.one where max_date_1< (today()-10);
/*select id from work.one where id=max(id);*/
update work.one
set id=(select max(id)-(max(id)-1) from work.process_cleanup);
quit;
/*%end;*/
/*%else;*/
/*output two;*/
run;
%mend clean;
%clean;

1. Use the {i} icon or the running man to post log or code.

This avoids issues like smileys.

2. Are you updating Teradata or a WORK data set?

3. What variable do you increment and why and when?
There is no where condition on your SET statement

4. Since you seem to be driving the process from a data step,
call execute() might be better suited than macros.

5. You can use the exist() function to test that a table exists and avoid error messages

6. Changing the thread title to something more relevant than "sas eg"

7. Loaded not loeaded 🙂
