java - 实体表错误 13037 : Illegal DOUBLE PREC constant

Question

尝试使用 Java JDBC 代码将记录添加到 SolidDB 时，出现以下错误。

下面是抛出异常的方法:

    public void addData(User data) {
    Connection conn = null;
    try {
        conn = dataSource.getConnection();
        if (conn == null || conn.isClosed()) {
            throw new RuntimeException("Could not open connection");
        }
        String query="INSERT INTO USER "
                + "(ID, NAME, PASSWORD, ENABLED, REQUIRE_RESET)"
                + "VALUES (?, ?, ?, ?, ?);";

        PreparedStatement ps = conn.prepareStatement(query);
        // "ID" column is INTEGER, and partition field in UserData is int.
        ps.setString(1, data.getId());
        ps.setString(2, data.getName());
        ps.setString(3, data.getPassword());
        // "ENABLED" column is INTEGER, and enabled field in UserData is boolean.
        ps.setInt(4, data.isEnabled()? 1:0); 
        ps.setString(5, data.isRequireReset()?"Y":"N");
        if (ps.executeUpdate() < 1) {
            throw new RuntimeException("Could not save User, executeUpdate() returned a value < 1");
        }

    } Catch (SQLException e) {
        throw new DataLayerException("Could not save the User Data.", e);
    } finally {
        if (conn != null) {
            try {
                conn.close();
            } catch (SQLException e) {
            }
        }
    }
}

我尝试过直接硬编码这些值，但仍然失败。如果我从插入语句中删除“ID”和“ENABLED”列，插入就会成功。

提前致谢。

PreparedStatement 索引为 1-based (另见setXX javadoc)。因为您使用 0，并且驱动程序不会警告您，所以所有内容都被“转移”，从而导致了问题。

修复:

ps.setString(1, data.getId());
ps.setString(2, data.getName());
ps.setString(3, data.getPassword());
ps.setInt(4, data.isEnabled()? 1:0); 
ps.setString(5, data.isRequireReset()?"Y":"N");
