Random Selection From Table Variable In Subquery As A Column In Select Statement

Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?




SET NOCOUNT ON


Declare @RandomRecordCount as int, @Counter as int
Select @RandomRecordCount = 1000

Declare @Type table (Name nvarchar(200) NOT NULL)
Declare @Source table (Name nvarchar(200) NOT NULL)
Declare @Users table (Name nvarchar(200) NOT NULL)
Declare @NumericBase table (Number int not null)

Set @Counter = 0

while @Counter < @RandomRecordCount
begin
Insert into @NumericBase(Number)Values(@Counter)
set @Counter = @Counter + 1
end


Insert into @Type(Name)
Select 'Type: Buick' UNION ALL
Select 'Type: Cadillac' UNION ALL
Select 'Type: Chevrolet' UNION ALL
Select 'Type: GMC'

Insert into @Source(Name)
Select 'Source: Japan' UNION ALL
Select 'Source: China' UNION ALL
Select 'Source: Spain' UNION ALL
Select 'Source: India' UNION ALL
Select 'Source: USA'

Insert into @Users(Name)
Select 'keith' UNION ALL
Select 'kevin' UNION ALL
Select 'chris' UNION ALL
Select 'chad' UNION ALL
Select 'brian'


select
1 ProviderId, -- static value
'' Identifier,
'' ClassificationCode,
(select TOP 1 Name from @Source order by newid()) Source,
(select TOP 1 Name from @Type order by newid()) Type

from @NumericBase
