JAVA通過呼叫資料庫函式呼叫儲存過程

package com.ljq.test; import java.sql.CallableStatement; import java.sql.Connection; import java.sql.SQLException; import java.sql.Types; publicclass ProceTest { publicstaticvoid main(String[] args) throws Exception { Connection conn =null; CallableStatement statement =null;
//?表示函式return的值, stu_proc是資料庫函式名 //儲存過程的out和in都是以引數傳進,這就是函式和儲存過程的區別之一 String sql ="{?=call stu_proc(?)}"; try { conn = ConnUtils.getConnection(); statement = conn.prepareCall(sql); statement.registerOutParameter(1, Types.VARCHAR); statement.setInt(
2, 36); statement.execute(); //具體值或資料未找到 String msg=statement.getString(1); System.out.println(msg); } catch (SQLException e) { e.printStackTrace(); } finally { ConnUtils.free(null, statement, conn); } } }
