oracle替换clob里面的某个特定的字符串

关键字：replace，dbms_lob.instr

第一步：判断clob里面是有包含某个特定的字符串：假如是说“/admin/ewebeditor/uploadfile/“

关键字：dbms_lob.instr

Code：

[sql] 
select st.id,st.content  
from t_d_strategy st where   dbms_lob.instr(st.content,'/admin/ewebeditor/uploadfile/') > 0;

第二步：用replace先替换下看是否是自己想要的结果

关键字：replace

Code：

[sql] 
select st.id,replace(st.content,'/admin/ewebeditor/uploadfile/','E:/resource/images/uploadfile/')   
from t_d_strategy st where  st.id = 553 and dbms_lob.instr(st.content,'/admin/ewebeditor/uploadfile/') > 0;

第三步：替换，前面的两步ok，肯定错不了的

关键字：update set

Code：

[sql] 
update t_d_strategy st set st.content = replace(st.content,'/admin/ewebeditor/uploadfile/','E:/resource/images/uploadfile/')   
where  st.id = 553 and dbms_lob.instr(st.content,'/admin/ewebeditor/uploadfile/') > 0;
