Question

我需要在文本中间附加文本。

1 EX：现有文字为："Monoclonal Anti-FLAG, Clone 6F7"

结果："<HIDE>Monoclonal Anti-<HIDE>FLAG, Clone 6F7"。

2 EX：现有文字为："Anti-100-KD subunit"

结果："<HIDE> Anti-</HIDE>100-KD subunit"

我想将<HIDE>标签附加到Anti和Monoclonal术语即将来临的地方。

select * from table where regexp_like(colnanme, '^(Monoclonal Anti|Anti)')

你能建议我该如何写这个。选择我有书面查询。

Answer 1

你可以使用替换和喜欢

 select replace(colname, 'Anti', '"<HIDE> Anti-</HIDE> ) 
 from table where colname like '%Anti%'
 and colname not like 'Monoclonal Anti%';

对于组合情况，您可以使用何时进行铅替换

  select case when  colname like '%Monoclonal Anti%'  
                then replace(colname, 'Monoclonal Anti', '"<HIDE> Monoclonal Anti-</HIDE> ) 
              when  colname like '%Anti%'  
                 then replace(colname, 'Anti', '"<HIDE> Anti-</HIDE> ) 
               else colname
              end 
 from table where colname like '%Anti%';

Answer 2

预测的某些正则表达式解决方案。

-- Start test data
with test_data as
    (select 'Monoclonal Anti-FLAG, Clone 6F7' as test_string from dual union all
     select 'Anti-100-KD subunit' from dual)
-- End test data     
select test_string,
       REGEXP_REPLACE(test_string,'(Monoclonal Anti-|Anti-)','<HIDE>\1</HIDE>')
from   test_data;


"TEST_STRING"                     "Result"
"Monoclonal Anti-FLAG, Clone 6F7" "<HIDE>Monoclonal Anti-</HIDE>FLAG, Clone 6F7"
"Anti-100-KD subunit"             "<HIDE>Anti-</HIDE>100-KD subunit"
