package com.t4b.jdbc.mysql.test; import java.sql.CallableStatement; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class TestMain { static { try { Class.forName("com.mysql.jdbc.Driver").newInstance(); } catch (Exception ex) { ex.printStackTrace(); } } public static void main(String[] args) { String name = "Python"; String publisher = "Wil"; Connection con = null; CallableStatement cstmt = null; try { con = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/library", "root", "pass123"); cstmt = con.prepareCall("{call book_update_publisher_proc(?,?)}"); cstmt.setString(1, name); cstmt.setString(2, publisher); cstmt.executeUpdate(); } catch (SQLException e) { e.printStackTrace(); } finally { if (con != null) { try { con.close(); } catch (SQLException e) { e.printStackTrace(); } } if (cstmt != null) { try { cstmt.close(); } catch (SQLException e) { e.printStackTrace(); } } } } }
