[FONT=Century Gothic]Hi Friends,
I need your help regarding data input to a query.
For example, I have 1000 records (student_name) in an excel file, I have to query the "students" table for getting the details of these 1000 student records.
how will I pass these 1000 records in the query as input /FONT]

[I]select * from students
where student_id in (' ', ' ',..... ' '_;[/I]
