关于sas 日期
各位高手
请教怎么找特定日期
Proc freq data=d2;
Table sex*year;
Where day( variable date)=30dec2012;
Run;
错误where clause operator requires compatible variables.
Would you please let me know how to fix it? Thanks.

where put(var_date,yymmdd10.)='2012-12-30'

Thanks

Thanks. It works! You have made my day! Did you get the credit? This has been solved.
