Id love to try it out!ThanksGSun, 03 Jul 2011 23:16:35 GMTGary Slaterhttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxGlad I could help, brian.Thu, 23 Dec 2010 16:10:50 GMTRBarryYounghttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxI'm not the one who asked for the code, but I used it anyway :-)Worked great.

' '2008-05-07 BYoung Created. ' 'NOTE: untested. Dim SourceCol As Smo.Column = SourceTable.Columns(ColName) Dim TargetCol As New Smo.Column(TargetTable, ColName) 'set the target column's properties using a Shallow Copy: With SourceCol TargetCol.DataType = .DataType TargetCol.Collation = .Collation If .Computed Then TargetCol.Computed = .Computed TargetCol.ComputedText = .ComputedText TargetCol.IsPersisted = .IsPersisted End If TargetCol.Default = .Default TargetCol.DefaultSchema = .DefaultSchema For Each xp As Smo.ExtendedProperty In .ExtendedProperties TargetCol.ExtendedProperties.Add( _ New Smo.ExtendedProperty(TargetCol, xp.Name, xp.Value)) Next If .Identity Then TargetCol.Identity = .Identity TargetCol.IdentityIncrement = .IdentityIncrement TargetCol.IdentitySeed = .IdentitySeed End If TargetCol.NotForReplication = .NotForReplication TargetCol.Nullable = .Nullable TargetCol.RowGuidCol = .RowGuidCol TargetCol.Rule = .Rule TargetCol.RuleSchema = .RuleSchema End With 'Find the column's position Dim ord As Integer = 0 While SourceTable.Columns.Item(ord) IsNot SourceCol ord += 1 End While TargetTable.Columns.Add(TargetCol, ord) TargetTable.Alter() End SubEnd Module[/code]You will have to test this yourself.Fri, 07 Nov 2008 08:08:49 GMTRBarryYounghttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxYou can search information_schema.columns in both systems, order by name, and the compare to see which columns are in the tables, or which ones aren't.Then you can use an ALTER TABLE command (or the SMO equivalent) to change the table.I'm not sure why you would put this in an application. Are you changing schema very often or is this just an exercise? The issues are that there could be defaults, rules, constraints, etc. imposed on a column. It's a simple process, but it has a lot of moving parts and it's easy to make mistakes. That's why a tool from someone like Apex or Red Gate is worth a few hundred dollars.Fri, 07 Nov 2008 06:46:39 GMTSteve Jones - SSC Editorhttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxSorry for not answering straight.I'm using SMO and vb.net (Even c# can do). I want to loop through the objects of a table then add the column to the other table if it doesn't exist in the other table.Fri, 07 Nov 2008 06:10:31 GMTthulani.moyanahttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxOK, since you did not say "Yes" to SMO, I am going to assume that SQL script is OK.Is the column at the end or in the middle of the column list? And is it involved in any indexes or keys?Fri, 07 Nov 2008 06:01:47 GMTRBarryYounghttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxThanx for the response.Yes, I have an application already but I need to take the exact copy of the column from one database to the other. If I have to set scripting options which options.The resulting databases should be identical schematically.This must be like cloning the column but somehow change the table to which it belongs and add it to that table and capture the Alter table script to run on the database you want to update.Thu, 06 Nov 2008 22:55:46 GMTthulani.moyanahttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxAre you asking in this forum because you wanted to know how to do this with client code using SMO?Thu, 06 Nov 2008 11:49:17 GMTRBarryYounghttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxThe best idea is to get RedGate SQLCompare or Apex SQL's product I think it is SQLDiff.Thu, 06 Nov 2008 10:52:16 GMT Jack Corbetthttp://www.sqlservercentral.com/Forums/Topic597928-22-1.aspxI need to compare two databases and update one of them. Suppose a table "Table A" is available in both databases but some columns are missing in the other table and I want to create an update sql script to update one database.I can add columns to the database to update and capture script by changing the execution mode, but the question is:How can I clone the column from one table to the other. I need to add the column as is with all constraints(i.e.) the exact copy of the other column.Any method of scripting the differences such that the resulting script with update the other table or all objects in the other database thus resulting in exactly the same databases.Any help will be appreciated.Thu, 06 Nov 2008 00:48:04 GMTthulani.moyana
