HI chinkey,

you can use this alternative for your requirements.

IF EXISTS
( SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE Column_Name = N’NameofColumn’ and Table_name = ‘NameOfTable’)

Yes sir, i have faced similar sitaution.when our development team produce new vesion release for exe or application,they have also changed for database. so for that we have to make single alter db script which can execute without fail.if column or table or any objects exists in production server then script will give error.for prevent this error and non technical person also can executes this script.

We can check using view INFORMATION_SCHEMA.COLUMNS.
IF EXISTS
( SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE Column_Name = N’NameofColumn’)
