Answer 1

Few problems here:

• After Create database Destination you need to use that database before you do the select * into TabDestination... as you will create TabDestination in some other DB.
• The Go in the middle of the begin...end block won’t work.
• To specify your database for the inserts to TabDesitination you’d be better to use the fully qualified name of the table than calling Use, eg Insert Destiation.dbo.TabDestination...
• You need to use If Exists (select... for the second if statement.
• Because your Database may not exists when the script compiles, a lot of the sql needs to be exec’d dynamically.

So your script could be re-written as:

if db_id('Destination')is null
begin
    Create database Destination    
    exec ('select * into Destination.dbo.TabDestination from [Source].[dbo].[TabSource]')
end 
else
begin

    if exists (select name from Destination.sys.objects where name = 'TabDestination' and type = 'u')
    insert into Destination.dbo.TabDestination select * from [Source].[dbo].[TabSource]

end
