Hi All,
I have to two DDL statements followed by a SELECT stmt which is ofcourse is not working 🙂
/*********************************
alter table foo add col2 int
create index idx on foo(col2)
select * from foo where col2 is null
**********************************/
Msg 207, Level 16, State 1, Line 5
Invalid column name 'col2'.
I can't use GO as batch separator because I have lots of variables declared that I'll be using again in the code.
Any workaround ideas greatly appreciated?

This works for me. Don't know if it still qualifies as single batch for you.

declare @sql nvarchar(max)

set @sql = '

alter table foo add col2 int;

create index idx on foo(col2);'

exec sp_executesql @sql;

set @sql = '

select * from foo where col2 is null ;'

exec sp_executesql @sql;

You need a semicolon or "go" statement between the different lines.

If some sort of statement delimiter is not between the statements SQL Server tries to resolve it as a single batch, and as the new field does not exist while it is trying to devise a query plan (and it's only a single query plan that is devised if there's only one batch) then the statement fails.

Thank you very much:) I tried earlier in dynamic sql but the only mistake I made was that I didn't execute my select statment i.e the second stmt after ALTER n CREATE INDEX.

Wonderful:) Work 100%
