If you are using SQL 2005+ then use the following :

SQL

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?'

I think this will not work for tables which are being referenced by foreign key

-- disable all constraints
EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

-- delete data in all tables
EXEC sp_MSForEachTable "DELETE FROM ?"

-- enable all constraints
EXEC sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

--some of the tables have identity columns we may want to reseed them
EXEC sp_MSforeachtable "DBCC CHECKIDENT ( '?', RESEED, 0)"

Try this:

SQL

declare @tblname int 
declare tbl_cursor cursor for
select name from sys.tables 
open tbl_cursor
fetch next from tbl_cursor into @tblname
while @@FETCH_STATUS = 0
begin
	EXECUTE ('truncate table '+ @tblname) <-- this is where i get an error
	fetch next from tbl_cursor into @tblname
end 
close tbl_cursor
deallocate tbl_cursor

In the case of dependency, this won't truncate the table. It'll throw the error at runtime. First truncate all the dependent table and then try this.
