This procedure deletes allrecords from all tables in the specified database
* (except schema 'sys'and databases master, model, tempdb and msdb)
* At first all constraints are disabled, afterwards all records are deleted
* (truncate would not work due to foreign keys) and
* finally all constraints are enabled
This is the updated version of the procedure:
- now it works without cursors
- it changes recover mode to Simple before cleaning the DB and resotores it after the job is finished
- it accepts a parameter (wich is default set to 1 = true) indicating whether the identities should be reseeded
