Oracle 索引的定义与约束相同

Question

我在使用 Oracle SQL Developer 时遇到问题，每当我转到表 TLCASENOTE 的索引部分时，它都会告诉我索引“索引 PK_TBLCASENOTE 的定义与约束 PK_TLCASENOTES 相同”。

我发现了这个 Oracle 表单帖子 但似乎没有人有解决方案。 这是用于制作表格的 DDL。

问题是因为如果不存在索引，Oracle 会自动为主键创建索引。冲突是因为尝试在同一列上创建索引，尽管名称略有不同。

我的最后一个地方是与表创建分开设置约束，这意味着您将使用以下步骤：

1. 创建表（无约束，包括主键）
2. 创建索引
3. 应用约束
