to connect to a database in fjyswan use the syntax"MAKECONNECT URL $url UNAME $username PWORD $password;"example:MAKECONNECT URL jdbc:oracle:thin:@rising-sun.microlab.cs.utexas.edu:1521:orcl UNAME CS347_RICK PWORD CS347_RICK;

this puts a Connection node on the AST which sets a variable in the visitor when called that is passed to all SQL tuple constructors.

SQL statements passed to a tuple are parsed into SPARQL using jsqlparser.

currently supported are the creation of tablesex : CREATE TABLE NEWTESTER (VAL1 NUMBER, VAL2 NUMBER, VAL3 NUMBER);

addition of elements into tablesex : INSERT INTO NEWTESTER (VAL1, VAL2, VAL3) VALUES (1, 2, 3);

select statements including equality where clausesex : SELECT * FROM NEWTESTER;ex : SELECT VAL2 FROM NEWTESTER;ex : SELECT VAL1, VAL2 FROM NEWTESTER WHERE VAL1 = 1;

tests/demo.py demonstrates these capabilities and tests/astdemo.py displays the abstract syntax tree after a connection statement.
