Delete all content from all tables

I have a relational data structure where I need to delete all data from all
tables. However, constraints are defined on the tables, so I need to delete
from bottom to top to avoid referential constraints.
Do you guys have an idea of how to accomplish this?
Thanks,
:o)

Who if not you shloud know the database structure
Take a look at OJ's script
create procedure usp_findreferences
@.tbname sysname=null
as
set nocount on
Print 'Referenced:'
select c1.table_name,
c1.column_name,
fkey=r.constraint_name,
referenced_parent_table=c2.table_name,
c2.column_name
from information_schema.constraint_column_usage c1 join
information_schema.referential_constraints r on
c1.constraint_name=r.constraint_name
join information_schema.constraint_column_usage c2 on
r.unique_constraint_name=c2.constraint_name
where c1.table_name=coalesce(@.tbname,c1.table_name)
order by case when @.tbname is null then c1.table_name else c2.table_name end
print ''
print 'Referencing:'
select c1.table_name,
c1.column_name,
fkey=r.constraint_name,
referencing_child_table=c2.table_name,
c2.column_name
from information_schema.constraint_column_usage c1 join
information_schema.referential_constraints r on
c1.constraint_name=r.unique_constraint_name
join information_schema.constraint_column_usage c2 on
r.constraint_name=c2.constraint_name
where c1.table_name=coalesce(@.tbname,c1.table_name)
order by case when @.tbname is null then c1.table_name else c2.table_name end
go
--test run
exec usp_findreferences 'Orders'
drop proc usp_findreferences

Why don't you simply create the DDL scripts, drop the database, and create a
fresh one using the scripts? BTW, don't forget to bavkup the db first!

The reason is that I don't really need to delete all data in the tables -
just the data related to a specific id - that is used in all tables.
The id is a job id and this id is a part of all tables relating to this
job.

How about setting up your FK's as FK's ON DELETE CASCADE?
Would this not solve your problem?

It would - if I needed to delete all data for a specific job. But this is
not what I need - I "just" need to delete the content in a number for
tables for a specific job. I do not want to delete the job entirely.
