我有一个问题，我的查询我不知道如何处理甲骨文，但是当我尝试相同的代码的SQL它的工作，但它显示我上面的错误编译我认为问题是在查询中，请有人帮助，如果知道如何处理这个。 感谢SQL状态[null];错误代码[17004];无效的列类型;嵌套的异常是java.sql.SQLException：无效列类型

如果您认为问题与查询有关，那么实际包含它可能是一个好主意......包含表定义也是一个好主意（一个或多个）查询正在击中的表格。 – JonK

@JonK谢谢兄弟，我想包括我的整个Java类，但由于一些奇怪的原因不工作..查询是返回jdbc.update（“INSERT INTO offers”+“（id，name，email，text）”+“VALUES”+“ （：id，：name，：email，：text）“，params）== 1; – Faisal
