Question

I Want to Copy some Data between two Data Bases, so I use an Insert query like the following:

INSERT INTO [NewDB].[MyTable]
(
[FirstName],
[LastName],
[Number]
)
(
SELECT [ST].[FirstName], [ST].[LastName], **SequentialNumber**
FROM [SourceDB].[SourceTable] AS [ST]
);
GO

But the new table have a new unique int not null column named Number as you see, so how can I insert sequential numbers (actually 10 digits number) with use the following script, Some thing like 1234567891, 1234567892, … , Does any one have any idea?

You can use ROW_NUMBER() function, e.g.:

INSERT INTO [NewDB].[MyTable]
(
    [FirstName],
    [LastName],
    [Number]
)

SELECT [ST].[FirstName], [ST].[LastName], ROW_NUMBER() OVER(ORDER BY [ST].[FirstName])
FROM [SourceDB].[SourceTable] AS [ST]
