ruby/sequel/mysql problem
 

newbie here.

have ruby/sequel/sqlite and windows 2003 server working smooth.

but have problem with mysql

"gem install mysql"

run a basic ruby test script, got error popop

"this application has failed to start because LIBMYSQL.dll was not
found. Re-installing the application may fix the problem."

Then copy LIBMYSQL.dll from my sql/bin to ruby/bin

this fixed the problem. Basic ruby / sql connection passed.

Then try to use sequel model with my sql code as following,

DB = Sequel.mysql(db_name, db_user, db_password, db_host, db_port)
class Test < Sequel::Model(:test)
end
tt = DB["test"].filter(:key => 'key').first

got error:

connection looks ok but error on the filter().first same code works
for sqlite.
