Question

我正在尝试将这个简单的代码用于在DDL SQL脚本中创建序列：

CREATE SEQUENCE seq START WITH 1 INCREMENT BY 1;
INSERT INTO MyTable (id, perc, tablex_id, tabley_id) SELECT NEXT VALUE FOR seq, 0, t.id, cb.id FROM tablex t, tabley cb;

但是我收到了这个错误：

为什么Hqdlb找不到序列seq？我正在使用Hsqldb 2.4.0。

Answer 1

您需要逐个执行这些SQL语句。

当多个SQL语句作为一个语句提交给数据库时，HSQLDB会在逐个执行语句之前解析并编译完整的文本。编译第二个语句时，第一个语句尚未执行，此时序列不存在。

Hsqldb找不到我刚创建的序列
