[HRS]

Hi

Please help me to find solutions  bellow matter

Recently  our library had  a problem of  issuing a few books to  wrong
patrons' name by  a staff member in circulation counter (  nearly  15
staff member work in the desk in   time to time /month as we have
roster based duties in the counter)

In looking SQL queries for

1. Who has issued  the given barcoded book? and when?
2. What  are the books issued by staff-ID( with time) ?
