dropsql

㈠ 如何在oracle中使用存储过程创建表,如果存在就先删除

没有权限?具体点 或者贴图!
不过应该是没有create table和drop table的权限吧,你试试赋下给此用户看看

㈡ 由于dm-0的存在而无法创建存储怎么办

如果是没有权限的话,照这下面做就OK了:
grant sysdba, dba, create session, create any table , create any view , create any index , create any procere ,
alter any table , alter any procere , drop any table , drop any view , drop any index , drop any procere ,
select any table , insert any table , update any table , delete any table
to test_data(数据库用户名);
首先我觉得你的逻辑有问题,既然数据库里面存在了表你就删除,但是你却把创建表的执行代码写在了else 条件里面;那意思如果数据库存在了你要创建的这张表,你的逻辑只是把它删除,但是却没有创建。
下面是我整理的代码你看看:

create or replace procere createtable(
tname varchar2
)
is
v_createsql varchar2(400);
v_dropsql varchar2(100);
v_count number(9);
begin

v_createsql:='create table '||tname||'(
a number(8) primary key,
b varchar2(20))';
v_dropsql:='drop table '||tname||' cascade constraints';
select count(*) into v_count from user_tables where table_name=upper('java7');
if v_count>0 then
execute immediate v_dropsql;
commit;
end if;

execute immediate v_createsql;
commit;
end;

begin
createtable('java7');
end;

-- select * from java7

㈢ SQL2005中怎样批量删除表

declare @Sql nvarchar(100); declare @dropSql nvarchar(100); declare my_cursor cursor for select name from sysobjects where name like 'R%' Open my_cursor fetch my_cursor into @Sql while @@fetch_status=0 begin set @dropSql='drop table'+' '+@Sql; EXECUTE sp_executesql @dropSql; end close my_cursor deallocate my_cursor return go 补充: 不好意思少写一个 declare @Sql nvarchar(100); declare @dropSql nvarchar(100); declare my_cursor cursor for select name from sysobjects where name like 'R%' Open my_cursor fetch my_cursor into @Sql while @@fetch_status=0 begin set @dropSql='drop table'+' '+@Sql; EXECUTE sp_executesql @dropSql; fetch my_cursor into @Sql end close my_cursor deallocate my_cursor return go 追问: 还是不行啊,报错,我搞不懂了! 消息3705,级别 16,状态 1,第 1 行 无法将 DROP TABLE 用于 'rsSetSignByGrade',因为 'rsSetSignByGrade' 是 过程。请使用 DROP PROCEDURE。 消息3705,级别 16,状态 1,第 1 行 无法将 DROP TABLE 用于 'rsCaculateTotalByGrade',因为 'rsCaculateTotalByGrade' 是 过程。请使用 DROP PROCEDURE。 消息3705,级别 16,状态 1,第 1 行 无法将 DROP TABLE 用于 'rsAddB20ToTables',因为 'rsAddB20ToTables' 是 过程。请使用 DROP PROCEDURE。

TEARDROPS IN THE RAIN
C.N.BLUE
NOW OR NEVER
qlseven制作
no one ever sees
no one feels the pain
teardrops in the rain
i wish upon a star i wonder where you are
i wish you're coming back to me again
and everything's the same like it used to be
...
i see the days go by and still i wonder why
i wonder why it has to be this way
why can't i have you here just like it used to be
i don't know which way to choose
how can i find a way to go on
i don't know if i can go on without you oh
......
even if my heart's still beating just for you
i really know you are not feeling like i do
and even if the sun is shining over me
how come i still freeze?
no one ever sees no one feels the pain
i shed teardrops in the rain
i wish i could fly i wonder what you say
i wish you're flying back to me again
hope everything's same like it used to be
i don't know which way to choose
how can i find a way to go on
i don't know if i can go on without you oh
even if my heart's still beating just for you
i really know you are not feeling like i do
and even if the sun is shining over me
how come i still freeze?
no one ever sees no one feels the pain
i shed teardrops in the rain
i shed teardrops in the rain
teardrops in the rain
even if my heart's still beating just for you
i really know you are not feeling like i do
and even if the sun is shining over me
how come i still freeze?
no one ever sees no one feels the pain
i shed teardrops in the rain
teardrops in the rain
teardrops in the rain
teardrops in the rain

㈥ 帮忙看一下这个存储过程,sqlserver200的,执行的时候报错

其实你可以把报错信息也贴上来,这样也省大家时间;

内容没细看,看起来应该是
Exec(@SQLString)
出错了;

这种最容易出现的是引号不匹配,多一个少一个,或者字串长度不够被截了,或者字符串中出现了全角字符~

不管怎样,建议在Exec之前,先Print 一下~
直接看Print出来的语句,我想你应该就不用求助别人了~
这个方法很好用,我一直用~

㈦ oracle下面如何使用'create table create table

想问什么??
