declare @yourstring varchar(100)
set @yourstring = 'na'
select * from example1 where selection <> @yourstring

i get what you say,
but I want is to have a clause that does not allow information to be saved if i try to insert in a selection = 'na',
that if I run an insert where selection = 'na' the insert statement is not completed and continue to the next item

example

INSERT INTO example1(item , selection)
VALUES ('door', 'excellent')
INSERT INTO example1(item , selection)
VALUES ('bed', 'na')
INSERT INTO example1(item , selection)
VALUES ('bath', 'na')
INSERT INTO example1(item , selection)
VALUES ('spoon', 'good')

id like my result be this ( bath 'na' and bed 'na' dont exist , didnt be saved)

id item selection
1 door excellent
2 spoon good

thanks in advanced, you are very patient and kind

oh ok. then what you want is instead of insert trigger like this


CREATE TRIGGER InsertValidate_trigger
ON example1
INSTEAD OF INSERT
AS
BEGIN
INSERT INTO example1
SELECT columns
FROM INSERTED
WHERE selection <> 'na'
END

Depending on your goal it might make more sense to put a check constraint on that column.

what he was suggesting was something like this


ALTER TABLE example1 ADD CONSTRAINT Chk_Data CHECK( selection <> 'na')

it will also avoid addition of any data with na value in selection

I have to update a table based on a weekly excel file
how can i update the table without inserting duplicate information and updating the state if the info exist in the table and doesnt exist anymore in the excel file ??
i know , the first step is impot the excel file to a table in sql
please follow the example below

2. Please post the DDL of your tables

**principal table
CREATE TABLE [dbo].[bill](
[idbill] [int] NULL,
[name] [nchar](10) NULL,
[debt] [int] NULL,
[state] [varchar](50) NULL
) ON [PRIMARY]

GO

EXAMPLE

IN MY PRINCIPAL TABLE IVE GOT THIS

idbill name debt State
11 peter 1000 open
16 samanta 1200 open
18 nicolas 800 open
23 jhon 200 open
32 sean 5000 open

FOR EXAMPLE , IN MY WEEKLY EXCEL IMPORT TABLE , IVE GOT THIS
(check that nicolas and sean dont appear anymore, and have 3 new rows (arnold, andy , michael)
idbill name debt state
11 peter 1000 open
16 samanta 1200 open

nope. just use OPENROWSET and excel will be considered like a table
then you can use LEFT JOIN and check for NULLs to identify new data and INNER JOIN to identify existing data

[code]
insert into bill
select c.columns...
from check c
left join bill b
on b.idbill = c.idbill
where b.idbill is null

update b
set b.state='closed'
from bill b
left join check c
on c.idbill = b.idbill
where c.idbill is null
[/code]
