----------------------------------------------------------

The JDBC objects implement enough methods to allow [Squirrel SQL|http://squirrel-sql.sourceforge.net/]
to be used to query data from a DBF file.

*1)* Open Squirrel SQL, and declare a Driver for DBase 3 using _"create a new Driver"_ button
in the Drivers tab.

*2)* Create an alias to the database you want to query, by the _"create a new Alias"_ button
in the Aliases tab

and connect to it :
!SIS184_connect_to_database.png!
(no need to use a user/password)


*3)* Query the table :
At the time this comment is put the table name checking is in progress : you can put the name
you want : a _SELECT * FROM <the only table contained in DBF>_ will always be executed.

*4)* You may also get table metadata :

> Following the SIS-180 (select * from DBF) this improvment will add the ability to :
> * Obtain field values from Integer and Double fields.
> * Add a simple WHERE clause with = , >, <, >=, <=, <> operators.
> Relational operators (AND, OR) _might be_ implemented too, depending on the ability of
parsing the query easily or not. Else, this feature will come in another JIRA.
