将自定义类型传递给 Oracle 过程

【中文标题】将自定义类型传递给 Oracle 过程

【英文标题】：Pass custom type to Oracle procedure

【问题描述】：

我有使用#include <occi.h>的C++代码：

std::vector< std::string > arr"qw", "er", "ty";
stmt = conn->createStatement(
  "BEGIN Clear_labels(:p_list1); END;");
setVector(stmt,1,arr,"MYCUSTOMTYPE");
stmt->execute();

现在我想编写 PL/SQL 命令将相同的命令发送到 DB。

MYCUSTOMTYPE：

TYPE "MYCUSTOMTYPE" as table of varchar2(255)

我觉得应该是这样的：

DECLARE list MYCUSTOMTYPE := MYCUSTOMTYPE("qw", "er", "ty")
BEGIN Clear_labels(list); END;
/

但我得到错误：

Invalid SQL type: sqlKind = UNINITIALIZED

【问题讨论】：

告诉我们MYCUSTOMTYPE和Clean_labels的定义

MYCUSTOMTYPE 在哪里定义？以及“它不起作用”是什么意思

我更新了帖子。

Potentially related，但请显示导致该错误的实际代码。

我添加了更多信息

【参考方案1】：

我决定试试sqlplus，结果成功了：

$ sqlplus tests/tests@cdb1

  6  /

我认为问题出在DBeaver。
