Question

我有一个像'from+google+world'

这样的字符串

我需要在任何地方搜索整个三个关键字的文本对于我们正在使用的单个查询，

select * from tabl name 
where desc like '%from%' 
and desc like '%google%' 
and desc like '%world%'

如何拆分字符串并将其与上述查询一起使用。 @p1+@p2+@p3

select * from tabl name 
where desc like '%@p1%' 
and desc like '%@p2%' 
and desc like '%@p3%'

Radu Gheorghiu：这个命令有50％的帮助它只是用De-Limiter分割字符串我必须得到有3个分裂字的列，例如我们必须得到描述'所有@p3的东西是@ p1去@ p2罚款'和desc不喜欢'所有@p3的东西都是@ p1正常'

Answer 1

这是您需要的代码here is a SQLFiddle

with test as 
    (select 'from+google+world' str from dual  
    )  
    select regexp_substr (str, '[^+]+', 1, rownum) split  
    from test  
    connect by level <= length (regexp_replace (str, '[^+]+'))  + 1

Answer 2

你的意思是这个输出吗？

from
google
world

WITH t AS (SELECT 'from+google+world' word FROM dual)
SELECT regexp_substr(word, '[[:alpha:]]+', 1, LEVEL) FROM T
CONNECT BY regexp_substr(word, '[[:alpha:]]+', 1, level) is not null;

你的意思是这个输出吗？

from
google
world

WITH t AS (SELECT 'from+google+world' word FROM dual)
SELECT regexp_substr(word, '[[:alpha:]]+', 1, LEVEL) FROM T
CONNECT BY regexp_substr(word, '[[:alpha:]]+', 1, level) is not null;

或者如果您在包含任何这些单词的表格内搜索，你可以CONTAINS从索引的oracle中运行：

Answer 3

SELECT * FROM tablename WHERE desc IN (
    SELECT regexp_substr('from+google+world','[^+]+', 1, level) FROM dual
    CONNECT BY regexp_substr('from+google+world', '[^+]+', 1, level)
    is not null
);

拆分字符串并在Like Command中使用
