I have two SKU's, example:
LEN=7: 7956616
LEN=6: 795661
OR
LEN=11: 13827502064
LEN=10: 1382750206
So I need to be able to search to find numbers that match their first x amount of numbers...
Something like this:
SELECT *FROM MyTableWHERE Mycolumn LIKE '%[0-9][0-9][0-9][0-9][0-9][0-9]%'
I need this to work to insert pricing too..so if I SKU of LEN=7 has a price, I need to be able to update that same price in the LEN=6 of a SKU with the first same 6 digits.
Thank you for any nudge.

Is this along the lines of what you're looking for?
DECLARE @Sku VARCHAR(7), @NewPrice DECIMAL(8,2); --Set your parameter values

UPDATE Product SET Price = @NewPrice WHERE SKU = @Sku OR (SKU = LEFT(@Sku, Len(@Sku-1)) AND LEN(Sku) = len(@Sku) - 1);

Excuse my typos and sometimes awful grammar. My fingers work faster than my brain does.

Slightly different method
😎

USE TEEST; GO SET NOCOUNT ON;

DECLARE @NUMLIST TABLE ( NM_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,SKU BIGINT NOT NULL ); INSERT INTO @NUMLIST(SKU) VALUES (7856614),(7956615),(7956616),(7756616),(795661);

DECLARE @NUMDIG INT = 6;

SELECT NL.NM_ID ,NL.SKU ,NL.SKU / POWER(10,CEILING(LOG10(NL.SKU)) - @NUMDIG) AS MATCH_DIGIT ,DENSE_RANK() OVER ( ORDER BY NL.SKU / POWER(10,CEILING(LOG10(NL.SKU)) - @NUMDIG) ) AS MATCH_GROUP FROM @NUMLIST NL;

Output
NM_ID SKU MATCH_DIGIT MATCH_GROUP ----------- -------------------- -------------------- -------------------- 4 7756616 775661 1 1 7856614 785661 2 2 7956615 795661 3 3 7956616 795661 3 5 795661 795661 3

Here are my suggestions depending on the data type.
DECLARE @NUMLIST TABLE ( NM_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,SKU BIGINT NOT NULL ); INSERT INTO @NUMLIST(SKU) VALUES (7856614),(7956615),(7956616),(7756616),(795661);

DECLARE @NUMDIG INT = 6;

SELECT long.NM_ID, long.SKU, ISNULL(short.SKU, long.SKU) AS matching FROM @NUMLIST long LEFT JOIN @NUMLIST short ON (long.SKU / 10 = short.SKU AND LEN( long.sku) = @NUMDIG + 1) GO

DECLARE @NUMLIST TABLE ( NM_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,SKU varchar(15) NOT NULL ); INSERT INTO @NUMLIST(SKU) VALUES (7856614),(7956615),(7956616),(7756616),(795661);

DECLARE @NUMDIG INT = 6;

SELECT long.NM_ID, long.SKU, ISNULL(short.SKU, long.SKU) AS matching FROM @NUMLIST long LEFT JOIN @NUMLIST short ON (long.SKU LIKE short.SKU + '_' AND LEN( long.sku) = @NUMDIG + 1)

I will only be comparing nvarchar(20) which is mainly INT data, I only care about INT's up to 12 in LEN

But I hope that you understand why did I post 2 options.

I do, but I need this to work, dynamically with any set of numbers, from 12 digits to 6 digits....out DB has 53,000 SKU's

Select * from Inventory where ItemNum ...

You have some INT hard coded....maybe I need to look it over again. ?

A quick test harness and a set based method to play around with
😎

USE TEEST; GO SET NOCOUNT ON;

DECLARE @NUM_ROWS INT = 100000;
