The datatype of dbc.Tabes.TableName is a CHAR(30), a comparison with "tablename = 'HI_WORLD'" results in

     "'HI_WORLD                      ' = 'HI_WORLD'"

and the shorter string is padded with blanks for comparison.

But LIKE never add pad characters, thus your comparison translates to

     "'HI_WORLD                      ' LIKE '%WORLD', which is FALSE.

Add a TRIM(TableName) or switch to dbc.TablesV which defines TableName as VARCHAR.
