# 3406 LIKE Operator Not Working Properly with Leading Wildcards

It appears a bug was introduced in DBISAM build 4.30 Build 3 in that the like operator only functions with the wildcard at the end of the search value, e.g.

Where the wildcard is used at the first position or at both ends of the search string all records are returned.

select * from t801 where ds_class like 'REAGENT%' order by ds_class

Comments

This was caused by a change to the LIKE functionality to improve the handling of MBCS operations.

Resolution

Fixed Problem on 3/20/2011 in version 4.30 build 4
