Question

我有一些使用MAMP从MySQL数据库导出的blob十六进制值。我试图将这些值添加到H2数据库，但我不断收到错误：

    org.h2.jdbc.JdbcSQLException: Hexadecimal string with odd number of characters: "80273753912952185238922745508880797601482513992540829416944108482201678079823009423240796439787688076562876906583780517704249256776629049440054030707230103901187860416530898080584543691951511619479802824069658267005899514817053628822676904964354186008390099680162497341280836375590099576180828248580706583256766125057680523862652582731318422096302127828322568212884418137380647350895148022669223845592468192584084729728626393575544"; SQL statement:

相同的INSERT行适用于MySQL。我在其他一些主题上看到，当H2的多线程模式启用时，可能会发生这种情况。我想尝试一下，但我不知道如何使用Play设置该参数！ 1.2.x的。

编辑：尝试了MULTI_THREADED但仍然遇到同样的错误。 EDIT2：忘记发布我使用的十六进制数字：

Answer 1

H2数据库将0x00aced0...解释为数字（Java BigDecimal），然后尝试将toString（）表示（十进制数）转换为十六进制编码二进制。

这当然不是你想要的，大约50％的情况都失败了。

因此，您需要使用0x00aced0...（引用）

而不是'00aced0...'

无法将blob从MySQL传输到H2
