I am sorry for my poor English.

I use SQL SERVER 7 and MDAC 2.6.

I have a DB named Manage, and there are three table, userinfo, resource and product, in it.

How to use SQL query statement to add a user into the DB, and grant the user in the userinfo, resource and product table?

For example, I want to add a user Jerry to the DB, and grant Jerry to the tree table with selecting, updating and deleting.

Thanks

1)
First, you have to check whether the login exists in the server. If not, use the following to add.

exec sp_addlogin jerry, password, defaultdatabase

Ex: sp_addlogin jerry, password, manage

2) Then logon to the SQLServer and execute the following commands to add him as a user in the database.

use manage
go
exec sp_adduser jerry, jerry
go

3) Grant access to the specific tables

grant all on userinfo to jerry
grant all on resource to jerry
grant all on product to jerry
go

NOTE: You can also define groups and grant access to the group level so that you do not have to grant access to each user.

1) Add a group:

exec sp_addgroup Usergroup1
go

2) The following command adds a user to particular group.

exec sp_adduser jerry, jerry, Usergroup1
go

3) Grant at the group level

grant select on table to Usergroup1

The coolthing about it is, you can add as many number users under the group and they all will have the same access level as you have granted to the group.

Drop a group:

exec sp_dropgroup  groupname


Drop a user:

exec sp_dropuser   username

If they own any objects in the database, you will not be able to drop the user.
