首先我们以一个简单的例子开始，在这个例子中，只存在一个返回值。存储过程如下
SQL> create or replace procedure lizhe (aa out varchar2)is
begin
select password into aa from passport where id='123111';
end lizhe;
/
补充说明：要注意的是这个存储过程存在一个（aa out varchar2）这样的标识，这是一个参数，out表示这是一个输出参数，在select语句中将password的值“into”到这个参数里
然后再java端：
public static void runProcedure(){
try {
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@192.168.0.159:1521:TOPS","YAC3","YAC3");
java.sql.CallableStatement cs = con.prepareCall("{call lizhe(?)}");
cs.registerOutParameter(1, java.sql.Types.VARCHAR);
cs.execute();
System.out.print("value2:" + cs.getString(1)); //取出字符串——关键
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
补充说明：cs.registerOutParameter(1, java.sql.Types.VARCHAR);
重点只有这一句
2.多个返回值的
SQL> CREATE OR REPLACE PACKAGE TESTPACKAGE AS
TYPE Test_CURSOR IS REF CURSOR;
end TESTPACKAGE;
/
Package created
SQL> CREATE OR REPLACE PROCEDURE TESTC(p_CURSOR out TESTPACKAGE.Test_CURSOR) IS
BEGIN
OPEN p_CURSOR FOR 'SELECT * FROM TB';
END TESTC;
/
Procedure created
import java.sql.*;
import java.io.OutputStream;
import java.io.Writer;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import oracle.jdbc.driver.*;
public class TestProcedure {
public TestProcedure() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@192.168.0.159:1521:tops";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "yac3", "yac3");
CallableStatement proc = null;
proc = conn.prepareCall("{call testc(?)}");
proc.registerOutParameter(1,oracle.jdbc.OracleTypes.CURSOR);
proc.executeQuery();
rs = (ResultSet)proc.getObject(1);
while(rs.next())
{
System.out.println(rs.getString("VALUE"));
}
}
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) {
}
}
}
}
