Do you really mean "truncate"? Truncate typically means that you trim
extra blank space from the ends of character strings. It doesn't sound
like that is what you want to do.
Do you mean "delete"? If so, you have to tell us whether you want to
delete all rows in all tables (leaving the database table structure
intact, but with no data), or you want to drop all tables from the
database, leaving the database empty, without tables or data. The
correct term for the first is "delete" (rows of data), while the
correct term for the second is "drop" (tables).
So... what is it you want to do?

The truncate statement works as follows:
truncate table TableName
So all you need to do is run it for each of the tables in your database.
You'd probably put this in a stored procedure to make it easier to run
subsequently.
However there are caveats -- you can't use it to on tables that are
replicating, for instance

Or on tables that are the target of foreign keys in other tables - even if
those other tables are empty!

Actually that is not a C# question.
Why not try: microsoft.publi c.sqlserver.new users?

I am trying to get some information to compare and contrast the
Truncate Table function and the Drop Table function. I know that
using Truncate Table is faster and saves the structure of the table
while the Drop Table will delete the table totally (data and
structure). My question is whether using one function over the other
will use up more capacity on the server?

Hi,
We have a heavily used production server and a table which logs every

clear it down as efficiently as possible. We would like to issue a
truncate table statement, but with millions of rows we are a bit wary
of how this will affect server performance. The alternative is to
delete is stages using rowcount but of course this will generate a
large amount of logging....

Once the transaction log has been invalidated, it can't be backed up
