Hello
I am using the following SQL statement to update the records in our database with a website address.
However, doing it this way would mean that I have to insert a new address_number each time that I want to add the website to a new record, and then run the query again.
I have managed to output a .csv file containg the address_number records, and I was wondering if I could amend my script to read this .csv file and insert the website address into every record where the address_number is shown in the .csv file?
Many thanks for your help.
Jon
declare @ComNum int
set @ComNum = (select max(communication_number)+1 from communications)
insert into [communications]
(address_number, contact_number, device, ex_directory, dialling_code, std_code, number, extension, notes, amended_by,
amended_on, cli_number, communication_number)
VALUES (127, NULL, 'WW', 'N', NULL, 'WW', 'W', NULL, 'www.abc.co.uk', 'Jon', 2007-11-29, NULL, @ComNum);

Hi Jon,

Not sure I folllow what you are trying to do.

If you need to load a csv I would use DTS or SSIS.

Hi Allen

Thanks for your reply. I'm not 100% sure that I need to use a .csv file but thought it might be one way around my problem.

I am trying to achieve this.... The first VALUE (i.e. address_number = 127) is just one of many address_number VALUES that I need to INSERT the website address for. So, the next address_number might be 128 then 129 then 130 and so on. I don't want to have to run the script x number of times and change the address_number each time to get what I want.

Is there a way in SQL to say update all address_numbers from the communications table with the other values shown in the statement (i.e. the website address etc), where the address_number is ('128','129', '130') and so on?

Thanks

Jon

Is value of the address_number column unique on the table?

jonclay_london SSC Journeyman Points: 91 More actions · Answer 4

Yes, each address has a different address_number so it is unique to that particular record.

Thanks,

Jon

This sounds like the address_number is your primary key on the table. Using an IDENTITY column would do away with the neeed for you to update the column manually.

Thanks Allen.

If this means that I have to insert a column into the database then I won't be able to do this. We receive frequent upgrades from the database supplier and any changes to the original structure of the tables/columns causes problems.

Is there any other way to get around this issue do you think?

Thanks for all your help so far.

I just know I'm not understanding the problem but to answer your question above...

Air code

UPDATE

communications

SET

MyField = @MyValue...

WHERE

address_number IN (101,102,103)

Thanks Allen. I'm sorry if I'm explaining things really badly. I'll just try once more (maybe it's not even possible in SQL, I'm not sure).

To do what I want to do I would have to do e.g.

declare @ComNum int

set @ComNum = (select max(communication_number)+1 from communications)

insert into [communications]

(address_number, contact_number, device, ex_directory, dialling_code, std_code, number, extension, notes, amended_by,

amended_on, cli_number, communication_number)

VALUES (127, NULL, 'WW', 'N', NULL, 'WW', 'W', NULL, 'www.abc.co.uk', 'Jon', 2007-11-29, NULL, @ComNum);

then clear the query and do...

declare @ComNum int

set @ComNum = (select max(communication_number)+1 from communications)

insert into [communications]

(address_number, contact_number, device, ex_directory, dialling_code, std_code, number, extension, notes, amended_by,

amended_on, cli_number, communication_number)

VALUES (128, NULL, 'WW', 'N', NULL, 'WW', 'W', NULL, 'www.abc.co.uk', 'Jon', 2007-11-29, NULL, @ComNum);

then clear the query and do...

declare @ComNum int

set @ComNum = (select max(communication_number)+1 from communications)

insert into [communications]

(address_number, contact_number, device, ex_directory, dialling_code, std_code, number, extension, notes, amended_by,

amended_on, cli_number, communication_number)

VALUES (129, NULL, 'WW', 'N', NULL, 'WW', 'W', NULL, 'www.abc.co.uk', 'Jon', 2007-11-29, NULL, @ComNum);

.... so basically the address_number VALUE changes each time.

What I want to do is get a script that avoids me having to run the above script 400 or so times with each different address_number number... if you get my drift!

Thanks so much and apologies once again!

Jon

Ok I'm following slowly. Where do the values other than address_number come from. Please tell me they are not hard coded into your script!

jonclay_london SSC Journeyman Points: 91 More actions · Answer 10

Thanks. The other values are the same for every record so I've done a select * for the communications table and copied over the values for the other records that are already in there - only the address_number needs to change. Is this what you mean?

allen davidson SSCertifiable Points: 7042 More actions · Answer 11

So the address_number changes _and_ the communication_number (otherwise we would not be having this discussion).

How about

SELECT TOP 400

IDENTITY(INT,1,1) AS Number

INTO

#Number

FROM

master.dbo.SysColumns sc1 CROSS JOIN master.dbo.SysColumns sc2 -- 12 million +

CREATE TABLE

communications -- simplified

(address_number INT NOT NULL,

notes VARCHAR(255) NOT NULL,

communications_number INT NOT NULL)

INSERT INTO

communications

(address_number,

-- other columns

notes,

communications_number)

SELECT

n1.Number,

-- other values

'www.abc.co.uk',

n1.Number + 200 -- 200 is an offset make it whatever you just to get this no different to address_number

FROM

#Number n1 WHERE n1.Number <= 100 -- however many you want

Hi Allen

Thanks for all your help. I'm due in a meeting now but will try the script tomorrow.

Cheers and best wishes,

Jon
