Execute Method (SqlStatement)
Executes the statement and returns result set.
Return Value
Result set returned by the statement execution.
This sample shows how to retrieve collection of statements that make up the script and execute them one by one.

"CREATE TABLE DEPT ("+
" DEPTNO INT PRIMARY KEY,"+
" DNAME VARCHAR(14),"+

"INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');"+
"INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');"+
"INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');"+
"SELECT * FROM DEPT";
