Question

我正在尝试在一个sql文件中运行一些语句，但它不起作用。

declare 
  new_sequence INTEGER;
begin 
  select LAST_NUMBER + 1 
    into new_sequence 
    from user_sequences 
   where SEQUENCE_NAME = 'MLTS_SEQUENCE';

  execute immediate 'Create sequence Table_SEQ start with '
      || new_sequence ||' increment by 1';
end;

如果我在eclipse数据库插件中运行带有'execute as one statement'选项的块，它可以工作。

我如何将sqlscript标记为将这些块作为一个语句运行，稍后使用sqlplus或不同于eclipse的内容执行脚本？

我在前面和/或最后尝试了GO，但这也没有用。

Answer 1

只要它在自己的行上并且左对齐，它在sql * plus中应该没问题：

SQL> create sequence MLTS_SEQUENCE start with 1 cache 20;

Sequence created.

SQL> select MLTS_SEQUENCE.nextval from dual;

   NEXTVAL
----------
         1

SQL> declare
  2    new_sequence INTEGER;
  3  begin
  4    select LAST_NUMBER + 1
  5      into new_sequence
  6      from user_sequences
  7     where SEQUENCE_NAME = 'MLTS_SEQUENCE';
  8
  9    execute immediate 'Create sequence Table_SEQ start with '
 10        || new_sequence ||' increment by 1';
 11  end;
 12  /

PL/SQL procedure successfully completed.

SQL> select Table_SEQ.nextval from dual;

   NEXTVAL
----------
        22

Answer 2

sqlplus的正确格式如下：

declare
  ...
begin
  ...
end;
