Hi.
I have a lot of independence queries. And I want to execute all of them in single script. Queries looks like below:
ALTER TABLE Table1
ADD
[Field1] nvarchar(4),
[Field2] nvarchar(2)
ALTER TABLE Table2
ADD CONSTRAINT Foo PRIMARY KEY ([ID])
ALTER TABLE Table3
ADD [Field1] nvarchar(50)
Look at second query. If we already have a primary key with name 'Foo' it throw error, and 3th query don't execute.
I want if one or more queries have problem they don't halt process and let remaining queries execute.
Thank you for help.

you could place GO statements between each command, but you still have to manually ignore the errors...makes it hard to determine which are "ignorable" errors and which are real.

instead, consider checking for the object before you create it:

IF NOT EXISTS(select 1 from sys.columns where name='Field1' and object_name(object_id) = 'Table1')

ALTER TABLE Table1 ADD [Field1] nvarchar(4);

IF NOT EXISTS(select 1 from sys.columns where name='Field2' and object_name(object_id) = 'Table1')

ALTER TABLE Table1 ADD [Field2] nvarchar(2);

IF NOT EXISTS(select * from sys.objects where name='Foo' and type_desc = 'PRIMARY_KEY_CONSTRAINT' and object_name(parent_object_id) = 'Table2')

ALTER TABLE Table2 ADD CONSTRAINT Foo PRIMARY KEY ([ID])

IF NOT EXISTS(select 1 from sys.columns where name='Field1' and object_name(object_id) = 'Table3')

ALTER TABLE Table1 ADD [Field1] nvarchar(50);
