由于前边有写java代码调用数据库,感觉应该把java调用存储过程也写一下,所以笔者补充该篇!
package testSpring;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleTypes;
public class Test1 {
public static void main(String[] args) {
Connection con=null;
PreparedStatement pre=null;
ResultSet res=null;
CallableStatement call=null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url="jdbc:oracle:thin:@192.168.224.87:1523:orcl";
String userName="gb_report";
String passWord="gb_report123$";
System.out.println("连接数据库成功!");
con=DriverManager.getConnection(url,userName,passWord);
call=con.prepareCall("{call P_COMMON.QUERY_PROVINCE_PAGE(?,?,?,?,?,?,?,?,?,?,?)}");//P_COMMON为包名,QUERY_PROVINCE_PAGE为存储过程名,?代表参数
call.registerOutParameter(4, OracleTypes.NUMBER);//参数下标为4及返回值的类型
call.registerOutParameter(5, OracleTypes.NUMBER);
call.registerOutParameter(7, OracleTypes.NUMBER);
call.registerOutParameter(8, OracleTypes.INTEGER);
call.registerOutParameter(9, OracleTypes.VARCHAR);
call.registerOutParameter(10,OracleTypes.VARCHAR);
call.registerOutParameter(11,OracleTypes.CURSOR);//注意这里返回值类型为游标
call.setString(1, "");//参数下标为1,输入参数类型为varchar(java对应string)
call.setString(2, "");
call.setString(3, "");
call.setString(6, "");
//执行
call.execute();
res = (ResultSet)call.getObject(11);//接受参数下标为11的返回值为游标类型,用ResultSet
while(res.next()){
System.out.println("行政ID:"+res.getString("ITEMID")+";省份名称:"+res.getString("ITEMNAME")+";");
}
} catch (Exception e) {
e.printStackTrace();
}finally{
try {
if(res!=null){
res.close();
}else if(pre!=null){
pre.close();
}else if (con!=null) {
con.close();
}
System.out.println("关闭连接!");
} catch (Exception e2) {
e2.printStackTrace();
}
}
}
}
