ESCAPE With LIKE Operator

ESCAPE With LIKE Operator

select ename from scott.emp where ename like '%_%';

But you will be surprised to see the results:

ENAME

Will dispaly all Data in the Table

it is because _ is a wild card character. That is _ stands for any character. So the query yielded all the rows.

modified query to get the desired output as below:


select ename from scott.emp where ename like '%#_%' escape '#';

ENAME
------------
