is it possible to store many name in a database column and the retrive
all the names? can a SQL INSERT statement do tat? as i know SQL
INSERT statement can insert a new row of datas into the database.
what is the SQL statement for inserting names into xyz in the
database table.
xyz is a pri key of a data.
as i know that if i use a SQL UPDATE statement, the information store
in the database eariler will be replaced with the new information.
i want the database to add on my data without replacing my orgainal
data.
i am using MS Access to do my database.
