Dear All,

While using

TO_NUMBER(TO_CHAR(START_DATE,'YYYY'))) < :V_ACC_YEAR)


it is causing a full table scan, resulting in slow performance.

CAn you please let me know, how it can be eliminated or what is the alternative?

I have an index on start_date.

Regards,

Jay.

TO_NUMBER(TO_CHAR(START_DATE,'YYYY'))) < :V_ACC_YEAR)

start_date < to_date('0101'|| :v_acc_year,'ddmmyyyy')
