I am using SQL Server. I want to add a single column named [DateCreated] to multiple tables. Is it possible that with a single statement I could add this column to all the tables in my database?
I stumble upon an answer by Joe Steffaneli in which he suggested a query which in turn returns rows consisting Alter table statements. Query is as follows :
select 'alter table ' + quotename(s.name) + '.' + quotename(t.name) + ' add [DateModified] datetime'
from sys.columns c
inner join sys.tables t
on c.object_id = t.object_id
inner join sys.schemas s
on t.schema_id = s.schema_id
left join sys.columns c2
on t.object_id = c2.object_id
and c2.name = 'DateModified'
where c.name = 'DateCreated'
and t.type = 'U'
and c2.column_id is null /* DateModified column does not already exist */
Is there any way that I can execute returned rows? Sorry for English.
