Could someone please offer me an alternative Perl solution to the following T-SQL code. I ask because the attempted solution below does not quite work as expected. I am trying to fill the Random_region_lookup_table_TEMP table. This table offers random subsets of geographic regions (to a fixed number) and this is repeated x number of times. The value of max(x) is the total number of generations. Each generation has the same number of regions. Each region subset is pulled from the same total set. No region is represented more than once in a single generation. Regions can be represented in multiple generations. 

DECLARE @Number_of_government_regions INT  

SET @Number_of_government_regions = (SELECT 354)



if exists(select 1 from INFORMATION_SCHEMA.tables where table_name = '
+MyNumbers') DROP TABLE MyNumbers;

--MyNumbers

--===== Create and populate the Tally table on the fly 

 SELECT    TOP 1000
    IDENTITY(INT,1,1) AS Nums   
   INTO dbo.MyNumbers   
   FROM Master.dbo.SysColumns sc1, 
        Master.dbo.SysColumns sc2

--===== Add a Primary Key to maximize performance  

 ALTER TABLE dbo.MyNumbers    
    ADD CONSTRAINT PK_MyNumbers_N         
        PRIMARY KEY CLUSTERED (Nums) WITH FILLFACTOR = 100





INSERT INTO  Random_region_lookup_table_TEMP (Generation_number, Place
+_key)
SELECT n.Nums, r.Number_count
FROM MyNumbers n CROSS JOIN Region_lookup r 
WHERE n.Nums <= @Number_of_repeats
ORDER BY n.Nums, NEWID()



UPDATE Random_region_lookup_table_TEMP
SET Place_key = (Place_key)%354 + 1



INSERT INTO Random_region_lookup_table_TEMP (Generation_number, Place_
+key)
SELECT n.Nums, r.Number_count
FROM MyNumbers n CROSS JOIN Region_lookup r
ORDER BY n.Nums, NEWID()
