Feb 24, 2003CPSC 203 by Jie Gao Plan for Labs  This lab  Basic operation in Access: create table, alter table, input data, append or insert data, sort records, …  Following labs  Advanced operation in Access: forms, queries, filters, …  Assignment requirements

Feb 24, 2003CPSC 203 by Jie Gao Creating A Table  Design table structure  Add fields  Select data type for fields  Set input mask for fields  Set primary key  Give the table a name

Feb 24, 2003CPSC 203 by Jie Gao Alter A Table  Change in design view  Everything could be changed  If delete a field, the data in that field will be deleted

Feb 24, 2003CPSC 203 by Jie Gao Edit Data  Input data in datasheet view  The format should conform to the mask  Move insert point among records using the navigator at the bottom of the datasheet view
