Caché/Ensemble/IRIS 中的 Global 通常在 SQL 访问中是不可见的
本示例将展示如何克服此限制。
Global 将呈现为一个表，其中包含它们的下标和存储的内容。
要查看的 global 通过一个静态 WHERE 条件传递给 SQL，
该条件需要 3 个参数:
- 名称 (必需)
- 开始下标 (可选)
- 结束下标 (可选)
只提供 global 名称将获得整个 global 的导出数据。
还可以为 global 提供扩展引用，并且由于这是 SQL 表，因此各种附加条件都适用。
小心， 在 SQL 和 Caché/Ensemble/IRIS 之间进行正确引用可能是一个挑战。
