This sample lets the user insert a DB_BOOK object in your database using EiffelStore insertion facilities.

Compiling

To compile the example:

  • Launch EiffelStudio.
  • Click Add project
  • Browse to $ISE_EIFFEL\examples\store\insert\.
  • Clicking open loads the selected project
  • Choose inserter.ecf
  • Select the target according to the installed DBMS
  • Choose the location where the project will be compiled, by default the same directory containing the configuration file.
  • Click OK.

Running

This sample lets you interact with your database through a console.

First you have to enter the database connection information:

  • For ODBC:

Database user authentication: Data Source Name: handson Name: smith Password: mypass

Note: Name and Password are not required with ODBC. If you don't need Name and Password, you can simply hit Return when prompted .

  • For Oracle:

Database user authentication: Name: smith@HANDSON Password: mypass

Note: You must specify the Oracle User Name and Net Service Name with the syntax <user>@<service> where <user> stands for the User Name and <service> stands for the Net Service Name.

Then you can insert a book in the database, for instance: What new book should I create? Author? John Smith Title? My book Quantity? 1 Price? 50 Year? 2001 Double value? 12.675 Object inserted

Note: If your database does not contain a DB_BOOK table, this example will create it.

==Under the Hood== This sample showcases the use of the DB_STORE class to perform database insertions where the SQL language is totally abstracted. The whole sample code is contained in the root class: * INSERTER for Oracle. * INSERTER_ODBC for ODBC.
