Hi
I need help for an SSIS problem
I Have a table with some fields like title, price , name and so on
The data of this table is
title, price , name
mars,10,john
mars,10,john
space ,12,alex
I want to add an id (using SSIS or any other idea) in front of title but for the same title should be the same id like
Id,title, price , name
111111,mars,10,john
111111,mars,10,john
234567, space ,12,alex
How can I do it

Since the table already exists you'd need to create another table and add the id column then load it with the data from the old table, delete the old table, and rename the new table to the original old tables name.

??. but I want the numbers of the id to be written automatically and not manualy. lets assume i have a table with 10,000 rows its not possible to do it mannually.

i want a process to add the id in the field automatically (and as i said it should be the same id when the title is same)

probably something like Generate an Auto Incremental Number in a SSIS Package but with the restriction that for the same tile i need the same number (id)

Set the column to be an Identity(1,1). Means that the first row will have id value of 1 and the next will be 2, and on and on.

i do not want to generate an increment but when there is same title should be the same id

Wait a sec, just reread your original post. You want the same id for common titles. Seems like you should have a lookup table. You could select distinct title into another table with an Identity(1,1) id column. then you could run an update joining the two tables on the title updating the id column sort of like below:

Update A

set id = b.id

from TableA as A inner join TableB as B

On A.title = B.title

a row_number() in a view might be a solution, since he wants a repeating value.

i think i would just a dd a calculated column that does the checksum; that would work.

/*

IDtitlepricename

599888mars10john

11098002space12alex

*/

;WITH MyCTE([title],[price],[name])

AS

(

SELECT 'mars','10','john' UNION ALL

SELECT 'space','12','alex'

)

SELECT CHECKSUM(title) As ID,* FROM MyCTE;

--ALTER TABLE MyTable ADD [ID] AS CHECKSUM(title) PERSISTED

Or you could use a lookup task and using a select distinct title along with row_number() to create the id to get the lookup data and then join on title
