Copying Views

Is there an easy way to copy all views from one database to another? Using
the import/export wizard tries to copy the data in a View to a Table in the
destination table. I don't want to create new tables just copy the view
object over (the databases are equivalent, one production, one for testing).
I use Views for pre-defined queries often used in the production
applications to give the end-user views of the data that makes more sense.
Am I using Views wrong?
By the way I have found a work around by right clicking on the view and go
to Script As -> CREATE TO -> New Query. Then change the first line from:
USE [SourceDatabaseName]
to
USE [DestinationDatabaseName]
This process is unyieldy though because I have to repeat the multi-step
process for every view I want to copy.
Thanks,
RyanRyan
You can use SQLDMO object library to script out all views and then run it on
destination server
Sub ScriptDB(strLogin As String, strPwd As String, _
strDataBase As String, StrFilePath As String)
Dim sql As Object
Dim db As Object
Dim objTrigger As Object
Dim intOptions As Long
Dim genObj
Set sql = CreateObject("SQLDMO.SQLServer")
Set db = CreateObject("SQLDMO.Database")
Set objTrigger = CreateObject("SQLDMO.Trigger")
Const sDrops As Integer = 1
Const sIncludeHeaders As Long = 131072
Const sDefault As Integer = 4
Const sAppendToFile As Integer = 256
Const sBindings As Integer = 128
Const SQLDMOScript2_NoCollation As Long = 8388608
' Set scripting options. Because you need to specify multiple behaviors
' for the ScriptType argument, you use "Or" to combine these.
intOptions = sDrops Or sIncludeHeaders Or _
sDefault Or sAppendToFile Or sBindings Or SQLDMOScript2_NoCollation
' Connect to local server
sql.Connect "(local)", strLogin, strPwd
Set db = sql.Databases(strDataBase, "dbo")
' Script Views, ignoring system views and informational schemas
For Each genObj In db.Views
If genObj.SystemObject = False Then
genObj.Script intOptions, StrFilePath
End If
Next
MsgBox "Finished generating SQL scripts."
End Sub
--usage
Call ScriptDB("UserName","Password","DatabaseName","C:\MyResults.SQL")

I wouldn't say you're "using" them wrong, I'd say you're "creating" them
wrong. The scripting method that you discovered is not a workaround,
it's the accepted method of working with database objects. You should
be creating your views with a script, and archiving that script in a
version control system, like Visual SourceSafe or Perforce. This allows
you to track the revision history of your objects, gives you a
"rollback" method for undo-ing changes, AND it makes your objects more
portable. To "copy" and object to a new location, you simply run the
CREATE script again, in the new location.

needing to create a non-production (test) database off of the production
database so I thought there would be a way to simply copy the entire
database (including objects such as views, stored procedures, etc) in one
fell swoop. I guess another option would be to detach the production
database and make a copy of the db files before reattaching it. The only
downside to this is downtime on the production side. Thanks for the info.

Why not just do a backup of the production DB, and restore that onto
your Dev server?
Tracy McKibben

restore doesn't the database structure have to already exist? At least I
couldn't find a way to do it otherwise. I just did a detach, copy file,
reattach to both the dev and production server. This seems to be the
easiest solution.

Nope, definately not true. You can restore a backup, give it a new
database name, and it will create the database "on the fly".

solutions.
