Question

我的表格中包含以下值

docid dcname doctitle 
1      **aa   **aaa01-01 
2      aa**   aafddg-02**
3      a**a   asds***90-05
4      abcd   abcd-06.

现在在这个表中我想过滤以**

开头和结尾的“Doctitles”值

我的结果应该是

dcid docname doctitle
3    a**a    asds***90-05
4    abcd    abcd-06

我正在使用以下查询，但获得的结果只是Doctitles，其中**位于中间

SELECT *
  FROM table1
 WHERE     doctitle NOT LIKE '**%'
       AND doctitle NOT LIKE '%**'
       AND doctitle LIKE '%**%'

这只给出了我的结果 dcid docname doctitle 3 a * a asds ** 90-05

需要帮助。

Answer 1

在没有and doctitle like '%**%'的情况下尝试您的查询应该是select * from table1 where doctitle not like '**%' and doctitle not like '%**'

另一种解决方案：

SELECT * FROM table1 WHERE LEFT(doctitle,2) != '**' AND RIGHT(doctitle,2) != '**'

Answer 2

尝试以下选项

select * from table1 where doctitle like '**%' and doctitle like '%**'

或

select * from table1 where doctitle like '**%'
UNION
select * from table1 where doctitle like '%**'

Answer 3

我尝试了它并且它有效 -

select * from 
(
select 
1    docid ,  '**aa' dcname  ,  '**aaa01-01' doctitle 
from dual
union all  
select 
2,      'aa**',   'aafddg-02**'
from dual
union all
select 
3 ,     'a**a' ,  'asds***90-05'
from dual
union all
select 
4  ,    'abcd'  , 'abcd-06.'
from dual
)
where doctitle not like '**%' and doctitle not like '%**'

Answer 4

假设您的意思是不希望doctitle以**开头或结尾，您只需要省略最后一个条件：

SELECT *
FROM   table1
WHERE  doctitle NOT LIKE '**%'
  AND  doctitle NOT LIKE '%**'

Answer 5

试试这个..

SELECT  *
FROM    table1
WHERE   doctitle LIKE '%**%'
AND     docid  NOT IN (SELECT docid  FROM tabel1 WHERE doctitle NOT LIKE '**%' )
AND     docid  NOT IN (SELECT docid  FROM tabel1 WHERE doctitle NOT LIKE '%**' )

Answer 6

SELECT * FROM table1 doct不是'％' 或者doctitle不喜欢'％'
