Question

有人可以帮助我吗？

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驱动程序：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;

但是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.**

任何想法？

感谢

在Teradata中，必须提交每个DDL语句，无法在同一事务中运行多个CREATE TABLE。

您必须删除BT / ET。

多个Teradata DDL查询以及使用Java的选择
