在java里调用时用下面的代码：

 

package com.hyq.src;
public class TestProcedureTWO {
public TestProcedureTWO() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl， " hyq "， " hyq ");
CallableStatement proc = null;
proc = conn.prepareCall("{ call HYQ.TESTB(?，?) }");
proc.setString(1， "100");
proc.registerOutParameter(2， Types.VARCHAR);
proc.execute();
String testPrint = proc.getString(2);
System.out.println("=testPrint=is="+testPrint);
}
catch (SQLException ex2) {
ex2.printStackTrace();
}
catch (Exception ex2) {
ex2.printStackTrace();
}
finally{
try {
if(rs != null){
rs.close();
if(stmt!=null){
stmt.close();
}
if(conn!=null){
conn.close();
}
}
}
catch (SQLException ex1) {
}
}
}
}
}
