java mysql编写的声明

Question

我正在尝试使用java进行数据库的简单插入，并告诉我我的sql语法已关闭。但是当我复制我打印出的字符串并将其放入phpmyadmin的sql命令时，它正确地执行命令，我似乎无法弄清楚java中的字符串查询是否有错误。

java.sql.PreparedStatement statement;

String physicanInsertQuery = "INSERT INTO physician_phi VALUES(?,?,?,?,?,?,?,?)";
statement = ddp.getConnect().prepareStatement(physicanInsertQuery);

statement.setString(1, "id");
statement.setString(2, "first");
statement.setString(3, "last");
statement.setString(4, "middle");
statement.setString(5, "male");
statement.setString(6, "8179999999");
statement.setString(7, "test@gmail.com");
statement.setString(8, "1991-5-15");
System.out.println(statement.toString());
statement.executeUpdate(physicanInsertQuery);
statement.close();

这是在我执行之前打印出来的查询。

INSERT INTO physician_phi VALUES('FML123','FirstName','LastName','MiddleName','Male','8179999999','john@server.department.company.com','1991-2-7')

这是它在控制台中显示的错误

....

这是db中的表。

Answer 1

您正在调用基本Statement.executeUpdate(String)方法，该方法与PreparedStatement无关，只是执行原始SQL字符串。

您需要在没有参数的情况下调用statement.executeUpdate()来使用派生方法n PreparedStatement。

Answer 2

你不需要终止;在你的SQL语句上。此外，您应该查看JPA，它将执行所有此数据库查询本身
