Create table in mysql

I try to create a new table using MYSQL command in asterisk.
This is what i write:
Query resultid ${connid} CREATE TABLE IF NOT EXISTS “conference_600” (“id” int(11) NOT NULL auto_increment, “channel_id” varchar(40), “number_in_line” int(2), PRIMARY KEY(“id”)")
and this is the warning that i get in the cli:
app_addon_sql_mysql.c:383 aMYSQL_query: aMYSQL_query: mysql_query failed. Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘“conference_600” (“id” int(11) NOT NULL auto_increment, “channel_id” varchar(40)’ at line 1

What is the problem do you think?
Do I in the direction or have a completely different way to do this?
