Question

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();

现在我想要写PL / SQL命令相同commad发送到数据库。

MYCUSTOMTYPE：

TYPE "MYCUSTOMTYPE" as table of varchar2(255)

我认为应该是这样的：

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

但我收到错误消息：

Invalid SQL type: sqlKind = UNINITIALIZED

我决定尝试sqlplus，结果证明是成功的：

$ sqlplus tests/tests@cdb1

我认为是DBeaver中的问题。
