BEGIN TRY
--------------------------------------------------------------------
-- Add New columns into product
--------------------------------------------------------------------
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N' [product]]') AND type in (N'U'))
BEGIN
----------------------------------------------------------------
-- Add New columns into product
--------------------------------------------------------------------
BEGIN TRANSACTION
ALTER TABLE product
ADD Type varchar(25) NULL
ALTER TABLE product
ADD ToDisplay bit NULL
--BEGIN TRANSACTION
INSERT INTO product VALUES
(6,'Not Started',NULL,NULL,0,'Clinical',0)
INSERT INTO product VALUES
(7,'In Progress',NULL,NULL,0,'Clinical',1)
INSERT INTO product VALUES
(8,'Complete - Resolved',NULL,NULL,0,'Clinical',1)
INSERT INTO product VALUES
(9,'Complete - Unresolved',NULL,NULL,0,'Clinical',1)

TYPE is a keyword, so you'll need to put it in brackets:

ALTER TABLE product

ALTER COLUMN [TYPE] VARCHAR(25) NOT NULL

well, i don't have a products table, to alter, and it was not included in your sample script, so here's mny best guesses:

you don't have GO statements after your ALTER TABLE statements. put one after your ALTER>

it looks like the table might have had, say 4 columns, and you added two columns, but then inserted into the table without explicitly naming columns; i'd think the inserts would fail.

regardless of where the [TYPE] column is being used, whether in the ALTER, INSERT, or SELECT, because it's a reserved word, it should be quoted [TYPE]

ALTER TABLE product ADD [Type] varchar(25) NULL;

ALTER TABLE product ADD ToDisplay bit NULL;

GO

INSERT INTO product(ColumnList)

--do more stuff

i am getting error at update statement

can you please post the actual error...

WHile the error you post in your post is about invalid column name type...

As it is reserve word so you have to put in brackets like [Type]

if i put go , it gives me error ,

i have everything in begin and commit transaction

do i need to refresh manually table after i add column and then i can update table

well, you are mixing up DML and DDL, and they should be completely seperate steps...first alter the tables if needed, then do your transaction.

something like this, and note i explicitly put a placeholder for the column names to be inserted into products; that's a best practice.

-- Add New columns into product

--------------------------------------------------------------------

IF EXISTS (SELECT * FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(N'product') AND TYPE IN (N'U'))

BEGIN

IF NOT EXISTS(SELECT 1 FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'product' AND name = 'Type')

ALTER TABLE product ADD TYPE VARCHAR(25) NULL;

IF NOT EXISTS(SELECT 1 FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'product' AND name = 'ToDisplay ')

ALTER TABLE product ADD ToDisplay BIT NULL;

END;

GO

BEGIN TRY

BEGIN TRANSACTION

IF EXISTS (SELECT * FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(N'product') AND TYPE IN (N'U'))

BEGIN
