日期格式错误java.sql.SQLException:无效的列类型 [英] Date Format Error java.sql.SQLException: Invalid column type

问题描述

我正在使用pattern="dd-MMM-yyyy"在JSF中显示日期.

I am displaying date in JSF using pattern="dd-MMM-yyyy".

当我尝试将日期值插入/更新到oracle数据库时，我得到

When I am trying to insert/update date values into my oracle DB, I am getting

java.sql.SQLException: Invalid column type

因为我插入或更新之前的日期格式是这种格式

because my date format before insert or update is in this format

如何正确地将日期值插入或更新到Oracle Db，什么是最好的方法?

How can I correctly insert or update my date values to Oracle Db and what is the best approach for doing this?

更新1

我的数据库插入代码.

private void editSchedule(Schedule schedule)
        Object[] values = { schedule.getStartDate(),
                schedule.getVacationId() };             
        Connection connection = null;       
        PreparedStatement preparedStatement = null; 
        try {                           
            connection = datacon.getConnection();               
            preparedStatement = prepareStatement(connection, SQL_EDIT, values);         
            preparedStatement.executeUpdate();          

        } catch (Exception e) {
            logger.info("errro "+e.getMessage());
            e.printStackTrace();
        } finally {
            // TODO: handle exception
            close(connection, preparedStatement);
        }

    }

PreparedStaement代码部分

PreparedStaement code part

public static PreparedStatement prepareStatement
        (Connection connection, String sql, Object... values)
            throws SQLException
    {
        PreparedStatement preparedStatement = connection.prepareStatement(sql
            );
        setValues(preparedStatement, values);
        return preparedStatement;
    }

    public static void setValues(PreparedStatement preparedStatement, Object... values)
        throws SQLException
    {
        for (int i = 0; i < values.length; i++) {
            preparedStatement.setObject(i + 1, values[i]);
            logger.info("sql  "+Arrays.asList(values));
        }
    }

推荐答案

听起来，您在插入/更新时试图将数据作为 text 包含在内.不要这样做-在PreparedStatement中使用java.sql.Date.引入不必要的字符串转换是一个非常糟糕的主意-它使您的代码非常脆弱，并使代码更加混乱:尽可能将数据保留在适当的数据类型中.

It sounds like you're trying to include the data as text when you're inserting/updating. Don't do that - use a java.sql.Date in a PreparedStatement. Introducing unnecessary string conversions is a really bad idea - it makes your code very brittle, and makes the code more confusijng: keep your data in an appropriate data type as long as you possibly can.
