重写SqlMembershipProvider的CreateUser方法,帮我看看这个查询语句
我想要在客户注册后自动加入一个我指定的用户组,所以重写了CreateUser,加入用户组的代码如下:
StringBuilder sb = new StringBuilder();
sb.Append( "DECLARE @RoleId UniqueIdentifier; ");
sb.Append( "DECLARE @UserId UniqueIdentifier; ");
sb.Append( "SELECT @RoleId=RoleId FROM aspnet_Roles WHERE LoweredRoleName=LOWER(@RoleName); ");
sb.Append( "SELECT @UserId=UserId FROM aspnet_Users WHERE LoweredUserName=LOWER(@UserName); ");
sb.Append( "IF @RoleId IS NOT NULL AND @UserId IS NOT NULL ");
sb.Append( "INSERT INTO aspnet_UsersInRoles(UserId,RoleId) VALUES(@UserId,@RoleId) ");
command.CommandText = sb.ToString();
command.Parameters.Add( "@UserName ", SqlDbType.NVarChar, 256).Value = username;
command.Parameters.Add( "@RoleName ", SqlDbType.NVarChar, 256).Value = this.DefaultUserRole;
command.ExecuteNonQuery();
执行完后aspnet_UsersInRoles表没有变化,是不是我的sql语句有问题?
[解决办法]
为什么不调试一下看看呢?就知道sql那里写错了阿
