Hi All I am using Drupal 6.20. I have constructured below query. str = *SELECT name, id, lft, rgt FROM resubmt_skill_ids AS node WHERE ( node.name LIKE "%sip%") ORDER BY node.lft* Then I call db_query() API. It did not return the expected records. On debugging, looks the query went as *SELECT name, id, lft, rgt FROM resubmt_skill_ids AS node WHERE ( node.nameLIKE "ip%") ORDER BY node.lft * Probably db_query API , considered %s as a string placeholder and removed from query string. Then I changed the query to *SELECT name, id, lft, rgt FROM resubmt_skill_ids AS node WHERE ( node.nameLIKE " %%sip%") ORDER BY node.lft* Above query returns expected records. My question is , when a token starts with "s", we will be facing above issue. What is the best way to resolve it. Can I follow the mechanism, where tokens starting with "s", will be changed to "%s" , so that in query the token will look like "%%s". Or do yo see any issues with this approach. Regards Austin
