like and regexp_like


Tag: sql,regex,oracle,oracle11g,regexp-like

For like we have %. for ex: if we give ad% it ll fetch all the records which starts with ad but i should use regexp_like. for regexp_like what can be used so that it acts as % for like. i cant use ^ad because from UI we ll give something like ad* to fetch.

Before query:select * from employee where fname like 'pr%';

Present query:select * from employee where fname regexp_like 'pr+';

for present query i m getting the values which contains pr but i want to get values which starts with pr.

Testdata: if pr* is given then i should get program etc i.e the value which starts with pr.


Try this one:

FROM employee 
WHERE REGEXP_LIKE (fname, '^pr(*)');


This one also seems to work as far as I can tell:

FROM employee 
WHERE REGEXP_LIKE (fname, '^pr.');

Or another one that works:

FROM employee
WHERE regexp_like(fname,'^pr');
