我创建一个test.sql文件，并放入其中:

I create a test.sql file and inside I put:

begin alter table table1 enable row movement; alter table table1 shrink space; end; /

这是不允许的吗?因为出现错误:

Is this not allowed? Because I get error:

Encountered the symbol "ALTER" when expecting one of the following: begin case declare exit for goto if loop mod null pragma raise return select update while with <an identifier> <a double-quoted delimited-identifier> <a bind variable> << close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe

推荐答案

您不能在PL/SQL块中将DDL作为静态SQL发布.如果要将这些命令放在PL/SQL块中，则需要使用动态SQL，即

You cannot issue DDL as static SQL in a PL/SQL block. If you want to put those commands in a PL/SQL block, you'd need to use dynamic SQL, i.e.

BEGIN EXECUTE IMMEDIATE 'alter table table1 enable row movement'; EXECUTE IMMEDIATE 'alter table table1 shrink space cascade'; END; /

但是，仅发出连续的SQL语句而不是发出单个PL/SQL块可能更容易.

It may be easier, however, to just issue consecutive SQL statements rather than issuing a single PL/SQL block.
