Just use Sql Management Studio and create a new table with the columns you need.

Did you create table having all columns you want??.. After creating table, use the following query to insert data from reg, userverify tables to userAcc table:

SQL

insert into [userAcc](username,password,etc)
select username,password,etc from reg

insert into [userAcc](secretcode,securityques,securityans)
select secretcode,securityques,securityans from userverify

You need a common cloumn in both the tables(reg & userverify) to join them. Otherwise join will be all possible combinations. In this case you can use above query or u need to create a column common to both tables.
