you should perform an update normally

UPDATE Table1 SET CompanyId = YourNewCompanyId

e.g

UPDATE Table1 SET CompanyId = 56


if you only want to change certain records, you can use a WHERE clause with that

e.g

UPDATE Table1 SET CompanyId = 56 WHERE CompanyId  = 99

Hi,

If your intention is to add the same data for another company then do the following

DECLARE @NewCompanyID AS INT
SET @NewCompanyID = 2 --or whatever is your new company id
INSERT INTO Table1
SELECT @NewCompanyID,
            Col2,
            Col3,
            .
            .
            .
            Coln
FROM   Table1
WHERE  CompanyId = 1 --provided that 1 is the company id that it is already in that table

Open in new window
