Does anyone know of a system procedure or have a stored procedure that would read the definition of a table on DATABASE1, create a script so that i could then CREATE the table on DATABASE2.
Or if you have any other ideas they would be appreciated.

ApexSQL and Redgate both sell products that will do that for you. It's not a simple process.

do you want all the tables to be copied.
else do the following.
@sql = 'Select * ' + ' INTO ' + @TargetDb+'.'+@Schema+'.'+ @TableName + ' From '+ @TableName ' + 'Where 1 = 2 '
exec @sql
so that should work out to copy the table.
but note this will not copy the indexes and other details but this should get you up and running.
Else let me know i should be able to put together some script to get this out of the door for you.

Here a little snippet of a script I will publish in next weeks:
Since now this only scripts the tables. The indexes and constraints are not included.

Thanks Flo. I always love your posts as they are very informative and easy to understand.
I am assuming I can read the system tables to find the constraints, indexes and such, then do alter table to apply.
The thing I was going to try was to set up an SSIS package that would import the tables. This would bring over the indexes and constraints, correct?

Thanks for that. Especially because I thought since now the statement is quiet ugly to understand because of no comments... :hehe:

Yes you can. All information are stored within the system tables. It's sometimes a bit tricky to find the right one but it exists.

Sorry, I don't know very much about SSIS since now. I don't know if SSIS does bring all the indexes, ...

As requested, I have another idea! Buy SQL Compare from Redgate (I have no connection with them but use the tool).
It will do the job you require but more importantly will sychronise any database you have with any other.
Frankly I have got more value out of this tool than nearly any other I ever bought!

Will that create all the tables from one database to another? I need to do a bunch of test scripts and bring in the new data using new packages that I create into a different test database. Obviously I can manually create each table from the old database and server into the new database and server but if I can avoid it, I'd rather do. So the issue - many tables in database and server to be copied (structure only, not data) to new database on new server. Thanks!

It does that and a lot more. You can try a fully functional version for 14 days, so there is no risk really.

There are other tools availabel, but I can vouch for this one.

Great. Will let you know how it works out. Thanks!

I do have this old script kicking around that I used for scripting Indexes and Constraints that may be of use alongside Flo's excellent post. It was only a scratch script so will not be 100% optimised and may be a little buggy, although it always worked for what I needed!

Of course, you could stick with the Redgate offering that I've used too and that's excellent for syncing
