Question

如何使用行映射器将数据插入表中？

我正在尝试这个 -

Employee user1 = jtemplate.queryForObject("INSERT INTO employee(id, name,salary) VALUES(10,'ABC',12333);",new BeanPropertyRowMapper<Employee>(Employee.class));

它给我带来了错误的sql语法错误。

但是查询可以在sql developer中使用。我做错了什么？

Exception in thread "main" org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [INSERT INTO employee(id, name,salary) VALUES(99,'ABC',12333)]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement

Answer 1

试试这个：

dt = datetime.now()

Answer 2

删除语句末尾的半冒号应该解决问题，像这样使用它。当使用jdbc模板时，在sql语句结尾处使用分号是不合适的

Employee user1 = jtemplate.queryForObject("INSERT INTO employee(id, name,salary) VALUES(10,'ABC',12333)",new BeanPropertyRowMapper<Employee>(Employee.class));

尝试使用它

    jtemplate.update("INSERT INTO Employee(ID, NAME, Salary) VALUES (?, ?, ?)",
     new Object[] { employee.getId(), employee.getName(), employee.getSalary() });

我使用它并且它正常工作并且没有显示错误

NamedParameterJdbcTemplate做您想要做的事情：

namedParameterJdbcTemplate.update(
    "INSERT INTO employee(id, name, salary) VALUES (:id, :name, :salary)",
    new BeanPropertySqlParameterSource(Employee.class));

使用RowMapper将记录插入表中
