继承自Statement CallableStatement继承自PreparedStatement ?...默认情况下,Statement 在创建时不是可池化的,而 PreparedStatement 和 CallableStatement 在创建时是可池化的。...CallableStatement详解 CallableStatement继承自prepareStatement,实现了存储过程函数调用的方法以及对于输出的处理。...上面给出了在MYSQL中,对于存储过程和函数的调用 再回过头来看CallableStatement的API解释就很容易理解了 CallableStatement是用于执行 SQL 存储过程的接口 JDBC...CallableStatement 可以返回一个 ResultSet 对象或多个 ResultSet 对象。

大家好,又见面了,我是全栈君 CallableStatement 对象为全部的 DBMS 提供了一种以标准形式调用已储存过程的方法。已储存过程储存在数据库中。...1、创建 CallableStatement 对象 CallableStatement 对象是用 Connection 方法 prepareCall 创建的。...下例创建 CallableStatement 的实例,当中含有对已储存过程 getTestData 调用。...对象所产生的结果,然后再用 CallableStatement.getXXX 方法来检索 OUT 參数。...检索全然部的结果后,就可用 CallableStatement.getXXX 方法来检索 OUT 參数中的值。
CallableStatement:执行数据库存储过程。...; //传递多参数 pstmt.setString(1, "a"); pstmt.setString(2, "b"); 处理存储过程语句接口:CallableStatement 创建 CallableStatement...对象 CallableStatement 对象是用 Connection 类中的 prepareCall() 方法创建。...将输入参数传给 CallableStatement 对象是通过 setXXX() 方法完成的。...如果存储过程返回的是输出参数,则在执行 CallableStatement 对象钱必须先注册每个输出参数的 JDBC 类型。

一旦通过 DriverManager 建立了连接,您就可以创建 Statement、PreparedStatement 或 CallableStatement 对象来执行 SQL 语句。...CallableStatement 接口用于执行存储过程或函数的调用。...; CallableStatement callableStatement = connection.prepareCall(callProcedure);...// 设置输入参数 callableStatement.setInt(1, 1001); // 注册输出参数 callableStatement.registerOutParameter...Salary: " + salary); // 关闭连接和 callableStatement callableStatement.close();
A、 JDBC提供了Statement、PreparedStatement 和 CallableStatement三种方式来执行查询语句,其中 Statement 用于通用查询, PreparedStatement...用于执行参数化查询,而 CallableStatement则是用于存储过程 B 、对于PreparedStatement来说,数据库可以使用已经编译过及定义好的执行计划,由于 PreparedStatement...2.Statement继承自Wrapper、PreparedStatement继承自Statement、CallableStatement继承自PreparedStatement。...3.Statement接口提供了执行语句和获取结果的基本方法; PreparedStatement接口添加了处理 IN 参数的方法; CallableStatement接口添加了处理 OUT 参数的方法...支持批量更新,批量删除; b.PreparedStatement: 可变参数的SQL,编译一次,执行多次,效率高; 安全性好,有效防止Sql注入等问题; 支持批量更新,批量删除; c.CallableStatement
