GUI To Create a DB Table

CS346Fall 2010

1

Methods to create a table

• At your local server and/or remote server– Use MySQL Console and create it interactively– Use a batch SQL script

• Use HTML and PHP scripts with goals:– Let user interactively define the fields– Identical development environment on local and

remote servers

2

Establish an identical environment

• Create a user on local server with the same <username> and <password> as your own on remote server (cs346)

• Create a database called <username> • See create_user_student.txt

3

Your Music collection

• Suppose you want to create a database table my_music with 8 attributes (columns)

• id• format• title• fname of artist• lname of artist• rec_label• my_notes• date_acq

4

Interaction of 3 scripts

• 12-1show_createtable.html to prompt for – Name of table– Number of attributes (columns)– Then call 12-1show_fielddef.php

• 12-1do_show_fielddef.php– Display a form for user to specify field names,

types, and length• 12-1do_createtable.php– Do the actual create table

Before running the scripts, list the tables in the database student by running http://127.0.0.1/student/m11/11-3db_listtables.php

Check if the table my_music has been really created in the database studentby running http://127.0.0.1/student/m11/11-3db_listtables.php

Hmm! The message is not quite correct. Intention is to show that the table is being added to the database ‘student’.Correction: remove the quotes around “DB_NAME”. But at this point, I need to drop the table and create it again. Let us fix the script, upload it to cs346 latgerand test again.
