Question

我遇到了Oracle SQL Developer的问题，每当我进入表TBLCASENOTE的索引部分时，它一直告诉我索引“索引PK_TBLCASENOTE的定义与约束PK_TBLCASENOTES相同”。

我发现了这个Oracle form post，但似乎没有人有解决方案。 This is the DDL制作表格。

Answer 1

问题是因为如果没有索引，Oracle会自动为主键创建索引。碰撞是因为尝试在同一列上创建索引，但名称略有不同。

我的上一个地方与表创建分开设置约束，这意味着您将使用以下步骤：

创建表格（无约束，包括主键）
创建索引
应用约束

Oracle索引的定义与约束相同
