I have a bind in the SQL query

SELECT * FROM users WHERE name LIKE '%?%'

I tried some regexp int the textbox es:
_jon \jon\ [jon] and some others but nothing work properly.

Any ideas?

Change your query to

select * from users where name like '?'

If you want to do a wildcard match, put the wildcards as part of the string that you’re binding to the variable. If you don’t want to do a wildcard match, then don’t.

Note that like and = have the same performance except when your wildcard character is first in the string (for example, '%bob') as in that case the query optimizer can’t use indexes as well to find the row(s) that you’re looking for.
