多个 Teradata DDL 查询以及使用 Java 的选择

Question

有人可以帮我吗？

我正在尝试使用 Java（Teradata JDBC 驱动程序）执行以下查询：

连接字符串：jdbc:teradata:/xxx.xx.xx.xx/database=XXX,tmode=TERA,charset=UTF8

JDBC驱动：com.teradata.jdbc.TeraDriver

BT;
create MULTISET VOLATILE table A as (
   select ...
) WITH DATA  primary index (xxx, xxx) on commit preserve rows;

create MULTISET VOLATILE table B as (
   select ...
) WITH DATA  primary index (xxx, xxx) on commit preserve rows;

create MULTISET VOLATILE table C as (
   select ...
) WITH DATA  primary index (xxx, xxx) on commit preserve rows;

select x.A, x.B, x.C from join A, B, C
ET;

但我收到以下错误消息：

Exception in thread "main" java.sql.SQLException: [Teradata Database] [TeraJDBC 15.10.00.05] [Error 3932] [SQLState 25000] **Only an ET or null statement is legal after a DDL Statement.**

有什么想法吗？

谢谢

在 Teradata 中，每个 DDL 语句都必须提交，无法在同一个事务中运行多个 CREATE TABLE。

您必须删除BT/ET。
